Subject:
cell adhesion; contact angle; extracellular matrix; hydrophilicity; mixing; stem cells; tensile strength; tissue engineering
Abstract:
... For skin tissue engineering, an ideal scaffold should mimic the natural extracellular matrix of the native skin. In this study, we reported a novel elastic sub-micron fiber scaffold blending poly (ε-caprolactone-co-lactide) (PLCL) and Pluronic at different ratios by electrospinning. PLCL and Pluronic were co-electrospun with the ratio of 100/0, 99/1, 95/5, 90/10, 85/15, and 75/25. These scaffolds ...

Abstract:
... While polyethersulfone (PES) represents outstanding oxidative, thermal and hydrolytic stability as well as good mechanical and film-forming properties, the hemocompatibility of PES membrane must be dramatically enhanced to reduce injections of anticoagulants during hemodialysis. In this study, a comblike amphiphilic block copolymer poly (vinyl pyrrolidone)-block-poly (acrylate-graft-poly (methyl m ...

Abstract:
... Comb-like amphiphilic copolymers (CLACs) consisting of functional chains of poly(vinyl pyrrolidone) and polyethersulfone-based hydrophobic chains were firstly synthesized by reversible addition–fragmentation chain transfer polymerization. The CLAC can be used as an additive to blend with polyethersulfone (PES) at any ratio due to the excellent miscibility, and then a surface segregation layer with ...
