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 ...
Bile acid bearing poly (vinyl chloride) nanofibers by combination of CuAAC click chemistry and electrospinning process
(Elsevier, 2020)
This study aims to deposit most common bile acids such as lithocholic acid (LCA) and chenodeoxycholic acid (CDCA) bearing poly (vinyl chloride) nanofiber (PVC-LCA and PVC-CDCA) coatings on glass slides surface using a ...
Electrospinning of Poly(1,4-Cyclohexanedimethylene Acetylene Dicarboxylate): Study on the Morphology, Wettability, Thermal and Biodegradation Behaviors
(Wiley-V C H Verlag Gmbh, 2020)
This study is conducted to evaluate the biodegradation and thermal features of poly(1,4-cyclohexanedimethylene acetylene dicarboxylate) (PCA) based films and fibers. The PCA is characterized by Fourier transform infrared ...
Synthesis and characterization of bile acid, poly (epsilon-caprolactone) and (L)-lysine diisocyanate ethyl ester based polyurethanes and investigation of their biodegradability properties
(Pergamon-Elsevier Science Ltd, 2021)
A series of environmentally friendly polyurethane (PU) films are successfully synthesized. For this purpose, ringopening polymerization (ROP) of epsilon-caprolactone (epsilon-CL) in the presence of cholic acid (CA) initiator, ...
