Wash-dry cycle induced changes in low-ordered parts of regenerated cellulosic fibers
(Wiley-Blackwell, Hoboken, 2012)
Three regenerated cellulosic fiber types: lyocell, viscose, and modal were subjected to repetitive wetdry treatments. Simulated treatments showed reorganization of the internal fiber structure which could be determined by ...
Electrospun polycaprolactone nanofibers functionalized with Achillea millefolium extract yield biomaterial with antibacterial, antioxidant and improved mechanical properties
(John Wiley and Sons Inc., 2023)
In this study, polycaprolactone (PCL), as a biocompatible polymer was functionalized by addition of medicinal plant extract- Achillea millefolium L. (yarrow). Nanofiber mats were fabricated from PCL solutions containing ...
The effect of natural modifiers for starch hydrophobization on performance of composite based on ethylene acrylic acid copolymer
(Wiley, Hoboken, 2021)
As a renewable resource, starch is considered to be fully biodegradable and nonpolluting to the environment but the hygroscopicity of starch is the main disadvantage for wider applicability in the production of a polymer-based ...
Development and characterisation of functional cocoa (Theobroma cacao L.)-based edible films
(Wiley, Hoboken, 2020)
The aim of this study was to develop functional edible films containing cocoa (Theobroma cacao L.) powder extract using alginate, pectin and chitosan in combination with proteins (whey protein isolate, soya and hemp protein). ...
Design of halloysite modification for improvement of mechanical properties of the epoxy based nanocomposites
(Polymer Composites, 2021)
In this study, halloysite nanotubes (HNT) were modified by: 3-glycidyloxypropyltrimethoxysilane (GLYMO), 3-aminopropyltrimethoxysilane (APTES), and 2,2-Bis[4-(glycidyloxy) phenyl] propane (DGEBA), and incorporated in the ...
Mechanical properties of acrylate matrix composite reinforced with manganese-aluminum layered double hydroxide
(John Wiley and Sons Inc., 2023)
Acrylate polymers are used in several applications such as dentistry, medicine, and industry. The modification of their properties using the reinforcement is of key importance for the possible applications. Layered double ...
Effect of surface activation of alumina particles on the performances of thermosetting-based composite materials
(Sage Publications Ltd, London, 2019)
Two types of alumina particles, commercial (c-Al2O3) and iron doped (Fe-Al2O3), were functionalized with 3-(aminopropyl)trimethoxysilane (one-step) and two-step consecutive process, i.e. firstly using 3-(aminopropyl)trim ...
The Effect of Nanofibrillated Tempo-oxidized Cotton Linters on the Strength and Optical Properties of Paper
(Journal of Natural Fibers, 2022)
This study elaborates the application of composite films based on nanofibrillated cellulose obtained from cotton linters oxidized in the 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO)/NaBr/NaClO system, with the use ...
Fracture micromechanisms in overaged 7000 alloy forgings
(Journal of Alloys and Compounds, 2007)
Micromechanisms controlling the fracture damage in 7000 alloy forgings are studied for T73-type heat treatments. Insight into the fracture modes are obtained by varying the microstructural attributes associated with the ...
Reuse potential of functionalized thermoplastic waste as reinforcement for thermoset polymers: Mechanical properties and erosion resistance
(SAGE Publications Ltd., 2021)
Two types of polymer waste materials, poly(ethylene terephthalate) (PET) and polycarbonate based Colombian Resin (CR-39), were used for the designing of fully recycled composite materials. Waste PET was employed for the ...
