AB  - Hemp fibers with different amount of hemicelluloses and lignin were subjected to atmospheric pressure dielectric barrier discharge under different conditions (40 W and 80 W power of discharge, const. time 120 s) in order to study influence of plasma treatment on their structure and sorption properties. Wettability of plasma treated samples, compared with precursors, increased due to the changes in hemp fiber surface chemistry confirmed by ATR FTIR spectroscopy and increased roughness as a consequence of intensive surface etching, observed by SEM. After plasma treatment, wettability was the highest for hemp fibers with lower content of hemicelluloses (increase up to 9 times), while wettability of raw hemp fibers and fibers with lower content of lignin increased about 5 and 2 times, respectively. This investigation shows that plasma can be successfully used for improvement of raw hemp fibers wettability, even to substitute the chemical treatment for some applications of hemp.

AB  - Cellulose fabrics (viscose and cotton) were treated with atmospheric pressure dielectric barrier discharge (DBD) in air. After DBD treatment, samples were characterized and volume electrical resistance was measured under different relative humidity conditions (phi=40-55 %). Results have shown that DBD treatment increases wettability and polar surface functional groups content, which consequently causes a decrease of volume electrical resistivity of cellulose fabrics in measured relative humidity range (phi=40-55 %). Metal ions (silver, copper, and zinc) were incorporated in untreated and plasma treated samples through sorption from aqueous solutions and incorporation of metal ions into plasma treated cellulose samples decreased electrical resistivity even further. Resistivity of cotton and viscose fabrics with incorporated metal ions followed the order Zn2+  gt  Cu2+  gt  Ag+. The most pronounced decrease, for entire order of a magnitude, was obtained by modification of cotton fabric with DBD and silver ions, where value of resistivity dropped from G Omega to a several dozens of M Omega.

AB  - In this work, a possibility to use atmospheric pressure plasma treatment to clean cotton fibers surface was investigated. Dielectric barrier discharge (DBD) operating in air was used as plasma source. After plasma treatment, cotton fibers were characterized using several surface techniques: SEM, XPS, ATR-FTIR and zeta potential measurement; also wettability was evaluated using capillary height measurement. Results of investigation showed that plasma treatment primarily affects cuticle and primary wall of cotton which provides cleaning of the fibers surface. This caused increase of polar groups accessibility and better wettability of cotton samples. An attempt has been made to locate influence of plasma treatment on different structural layers of cotton fibers using different surface techniques. In addition, surface charge was investigated through measuring streaming potential and a connection was established between zeta potential and plasma treatment time. Furthermore, it was shown that measuring of zeta potential could be used as an additional technique to track changes and elucidate mechanisms of plasma treatment influence on cotton fibers.

AB  - Plasma treatment of viscose cellulose fabric was performed using the atmospheric pressure dielectric barrier discharge (DBD) in nitrogen. Samples were treated using nonthermal plasma, and change of sorption properties with plasma energy density was investigated. It was found that using low energy of discharge, modified viscose samples become less hydrophilic and their wettability is significantly reduced. The observed hydrophobic effect was investigated and confirmed throughout series of experiments, by measuring a change in wetting time and in the level of aqueous liquid repellency. Structural changes were monitored using SEM, AFM, and XPS. It was established that increase of roughness combined with removal of hydrophilic polar groups from the surface of cellulose using plasma represents a novel approach to impart hydrophobicity onto hydrophilic textile. An additional binding of copper ions to nitrogen DBD treated cellulose produces a cross-linking effect, i.e., an occupation of remaining hydrophilic groups on the fabric surface and provides so called "petal effect'' where drops of water stick to the fabric surface when the fabric is tilted for 1808. This novel procedure for obtaining hydrophobic cellulose could be used for a preparation of special protective textile materials with cost and time effective methods and chemicals.

AB  - Multi-walled carbon nanotubes (MWCNTs) and graphene nanoplatelets (GNPs) have been functionalized by dielectric barrier discharge (DBD) in air. The extent of functionalization of MWCNTs and GNPs reaches a maximum at the delivered discharge energy of 720 and 240J mg(-1), respectively. Further exposure to plasma leads to reduction of functional groups from the surface of the treated nanomaterials. It has also been demonstrated that DBD plasma does not produce dramatic structural changes in MWCNTs, while flakes of the treated GNPs become thinner and smaller in the lateral size. Conductive thin films, obtained by drop casting a solution of the treated nanomaterials in N-methyl-1-pyrrolidone on poly(methyl methacrylate) substrate, show significantly lower sheet resistance.

AB  - In this work, the effect of dielectric barrier discharge (DBD) in ambient air on preparation of antimicrobial viscose fabric was studied. DBD plasma treatment was applied under constant discharge power and different exposure times. Vertical wicking test was used to evaluate optimal conditions for plasma treatment of viscose in order to increase fabrics' wettability and consequently improve sorption properties. Investigation of aging effect of plasma treatment revealed that there was no significant change in wettability of viscose samples 21 days after plasma treatment, which suggests good durability of treatment. After DBD plasma treatment, fabrics were modified with silver and copper ions in order to impart antimicrobial properties on viscose fabric. Viscose samples, modified with Ag (I) and Cu (II) ions immediately and 1, 7, 14 and 21 days after DBD treatment were tested in vitro against microorganisms S. aureus, E. coli and C. albicans using agar diffusion test. Obtained results showed that modification with DBD, prior to sorption of Ag (I) and Cu (II) ions, leads to improvement of antimicrobial activity of viscose samples, with a possibility to provide specific activity against different microorganisms by altering the days after DBD treatment prior ions sorption.

AB  - Dielectric barrier discharge (DBD) pretreatments in air, nitrogen and oxygen plasma of viscose and cotton fabrics with subsequent immobilization of silver were studied. Surface activation of treated fibers was evaluated through subsequent sorption of silver from aqueous AgNO3 solution, after which changes in the surface morphology were monitored and quantity of silver deposition on fabric was measured. The plasma treatment was done in volume DBD discharge with the gap distance between electrodes of 0.5 and 2 mm. Depending on the gas used in pretreatment, significant difference in the way silver bonds to the textile surface was found. Nitrogen plasma pretreatment with gap distance of 0.5 mm led to the homogeneous fiber coating by silver nanoparticles with average size up to 300 nm estimated by SEM, while fibers treated in oxygen plasma adsorbed silver in a form of ions. The plasma pretreatment in air leads to changes that contain features of fibers treated in both nitrogen and oxygen DBD plasma. Distinct difference of used configuration of the plasma source is a use of gap distance 0.5 mm, which is in order of textile thickness. Observed results allow us to report a new way how to immobilize silver nanoparticles onto textile fibers using plasma pretreatment with subsequent sorption of silver from aqueous solution.

AB  - The aim of this study was to examine and compare the potentials of two different ambient air plasma treatments: volume dielectric barrier discharge and diffuse coplanar surface barrier discharge, for the activation of polypropylene (PP) nonwovens surface. This was done in order to enhance the deposition of gold nanoparticles (AuNPs) onto PP surface. AuNPs were attached onto PP surface from colloidal solution prepared without stabilizers. Scanning electron microscopy, atomic force microscopy, attenuated total reflection-Fourier transform infrared spectroscopy, water absorption, and AuNPs uptake were used to assess the surface changes due to the plasma treatment, and to evaluate the durability of the achieved treatment effects. Finally, as a very important aspiration of the research, antibacterial activity of AuNPs loaded PP nonwovens against pathogens Staphylococcus aureus and Escherichia coli was evaluated in vitro. The plasma modified PP nonwovens have highly improved wetting and sorption properties. The PP nonwovens loaded with 17-62 mg/kg AuNPs exhibit antibacterial activity against tested pathogens. Surprisingly, this activity was enhanced by the first sample rinsing.

AB  - The aim of this work is plasma activation of nonwoven polypropylene (PP) using two different ambient air plasma sources: volume dielectric barrier discharge (DBD) and diffuse coplanar surface barrier discharge (DCSBD) and its functionalization by silver ion deposition. To assess the surface changes on the nonwoven PP due to plasma treatment scanning electron microscopy (SEM), atomic force microscopy (AFM) and inductively coupled plasma-optical emission spectroscopy (ICP-OES), were used. Changes in sorption properties of the plasma treated nonwoven PP were evaluated by silver ion uptake. The antimicrobial activity of silver loaded nonwoven PP against the pathogens Escherichia coli, Staphylococcus aureus and Candida albicans was evaluated in vitro. The plasma treatment of PP fabrics resulted in highly improved sorption properties. The quantity of bonded silver ions was in the range from 300 to 5600 mg/kg. Obtained silver loaded nonwoven PP shows antimicrobial activity against the tested pathogens.
