Effect of polyvinyl alcohol/chitosan blend ratios on morphological, optical, and thermal properties of electrospun nanofibers
(2019)
In this study, the electrospinning method was used to prepare polyvinyl alcohol (PVA)/chitosan (CS) blend nanofibers from their solutions. The effect of blend ratios (PVA/CS: 1%, 3%, 5%, and 7% (w/w)), applied voltage, and ...
Soybean Oil Modified Bio-based Poly(vinyl alcohol)s via Ring-Opening Polymerization
(Springer, 2019)
In this paper, a simple method to modify the poly(vinyl alcohol) (PVA) through ring-opening reaction of epoxidized soybean oil (ESBO), catalyzed by hydrochloric acid is reported. The effect of ESBO loading ratio, in terms ...
Design of Colloidally Stable and Non-Toxic Petox-Based Polymersomes for Cargo Molecule Encapsulation
(Wiley-V C H Verlag Gmbh, 2019)
Polymersomes are vesicular constructs formed by the self-assembly of polymer amphiphiles. Here we report the fabrication of PEtOx-b-PLA polymersomes at physiological pH/salt concentration and the determination of a f(PEtOx) ...
Polypropylene microfibers via solution electrospinning under ambient conditions
(Wiley, 2019)
Uniform beadless fibers of chlorinated polypropylene (PP-Cl) are prepared by electrospinning of PP-Cl solutions in tetrahydrofuran at different concentrations, feed rates, applied voltages, and tip-to-collector distances ...
The emerging applications of click chemistry reactions in the modification of industrial polymers
(Royal Soc Chemistry, 2019)
Polymer modification has been practiced since the very early technological development of human kind by transforming natural resources into value-added commodities. Ever since the middle of the last century in which ...
Polymeric fluorescent film sensor based on poly(azomethine-urethane): Ion sensing and surface properties
(Elsevier Science Bv, 2019)
A polymeric film sensor containing poly(azomethine-urethane) was easily fabricated using the dip-coating technique and ion sensing property of this film toward different metal cations investigated. Fluorescence measurements ...
Poly(azomethine-urethane) and zeolite-based composite: Fluorescent biosensor for DNA detection
(Pergamon-Elsevier Science Ltd, 2019)
In the present paper, a highly selective and sensitive fluorescent biosensor based on poly(azomethine-urethane) and zeolite for the determination of DNA molecules was developed. Zeolite was chosen to enhance with anionic ...
Synthesis and characterization of biodegradable polyurethanes made from cholic acid and L-lysine diisocyanate ethyl ester
(Elsevier Sci Ltd, 2019)
In this work, a series of biodegradable polyurethanes (PURs) based on cholic acid (CA) and L-lysine diisocyanate ethyl ester (L-LDI) that are renewable difunctional building blocks is synthesized by step growth polymerization. ...
Effect of flow rate on wetting and optical properties of electrospun poly(vinyl acetate) micro-fibers
(Springer, 2019)
In this work, extremely hydrophobic micro-fibers from polyvinyl acetate (PVAc) were obtained by changing the flow rate of the solution in electrospinning process. Surface morphologies and wettability of the fiber surfaces ...
