Development and characterization of thermosensitive hydrogels based on poly(N-isopropylacrylamide) and calcium alginate
(Wiley, Hoboken, 2012)
This work refers to the synthesis and characterization of thermosensitive hydrogels based on interpenetrating polymer networks (IPNs) of poly(N-isopropylacrylamide) (PNIPAAm) and calcium alginate in the form of films. The ...
Rheological Properties of Hydroxyl-Terminated and End-Capped Aliphatic Hyperbranched Polyesters
(Wiley, Hoboken, 2015)
The rheological behavior of two series of aliphatic hyperbranched (HB) polyesters, based on 2,2-bis(hydroxymethyl) propionic acid (bis-MPA) and di-trimethylol propane (Di-TMP) as a tetrafunctional core, was studied. The ...
Polymerization of Itaconic Acid Initiated by a Potassium Persulfate/N,N-Dimethylethanolamine System
(Wiley, Hoboken, 2008)
The synthesis and characterization of poly (itaconic acid) (PIA) with a novel initiator/activator system is presented. The initiator in this system was potassium persulfate, whereas the activator was N,N-dimethylethanolamine ...
High strength thermoresponsive semi-IPN hydrogels reinforced with nanoclays
(Wiley Periodicals, Inc., 2012)
Two series of nanoclay reinforced, thermoresponsive hydrogels were prepared, one based on poly(N-isopropylacrylamide) (PNIPA) and the other on semi-interpenetrating networks containing PNIPA and poly(N-vinyl pyrrolidone) ...
In Vitro Silver Ion Release Kinetics from Nanosilver/Poly(vinyl alcohol) Hydrogels Synthesized by Gamma Irradiation
(Wiley, Hoboken, 2014)
A nanosilver (nano-Ag)/poly(vinyl alcohol) (PVA) hydrogel device was synthesized with irradiation because it is a highly suitable tool for enhanced nano-Ag technologies and biocompatible controlled release formulations. ...
Hydrogels reinforced with nanoclays with improved response rate
(Wiley-Blackwell, Hoboken, 2017)
Two series of semiinterpenetrating networks (SIPN) based on linear hydrophilic poly(vinyl alcohol) (PVA) and thermoresponsive poly(N-isopropylacrylamide) (PNIPA), physically crosslinked with inorganic clay, are presented. ...
Nonisothermal melt-crystallization kinetics of hydroxyapatite-filled poly(3-hydroxybutyrate) composites
(Wiley, Hoboken, 2006)
The knowledge of biomedical implants ranging from drug delivery devices to tissue engineering and based on bioresorbable polymer composites is increasing, but the study of the crystallization kinetics of these kinds of ...
Effect of low-temperature plasma and chitosan treatment on wool dyeing with acid red 27
(John Wiley & Sons Inc, Hoboken, 2005)
This study examines in detail the influence of low-temperature plasma and biopolymer chitosan treatments on wool dyeability. Wool knitted fabrics were treated and characterized by whiteness and shrink-resistance measurements. ...
Synthesis and characterization of biodegradable aliphatic copolyesters with poly(tetramethylene oxide) soft segments
(Wiley, Hoboken, 2007)
A series of aliphatic poly(ether-ester)s based on flexible poly(tetramethylene oxide) (PTMO) and hard poly (butylene succinate) (PBS) segments were synthesized by the catalyzed two-step transesterification reaction of ...
Mathematical Model of Gentamicin Sulfate Release from a Bioactive Textile Material as a Transdermal System Under In Vitro Conditions
(John Wiley & Sons Inc, Hoboken, 2010)
A mathematical model was developed to estimate the release of gentamicin sulfate from a bioactive textile material as a transdermal system for wound dressing. The gentamicin sulfate released from the antibiotic/chitosan ...
