Poly (lactide-co-glycolide) (PLGA, LA/GA = 80/20) with different L-lactide and D-lactide molar ratio (L-LA/D-LA = 1.0∼0.5) has been synthesized, and electrospun into nanofibrous membranes. The obtained copolymers were characterized by 1HNMR, Polarimeter, GPC and DSC. The relationship between the contraction of the membranes and the L-LA/D-LA ratio of copolymers has been investigated through DSC, SEM...
Control of dimensional stability is crucial for using electrospun membranes in biomedical and tissue engineering applications. In this study, the contraction of electrospun membranes of poly(l-lactide-co-glycolide) (PLLGA) after stretch was investigated. Then, by adding PLLGA-b-polyethylene glycol (PLLGA-PEG), the contraction of the membranes was controlled. In addition, the mechanical properties...
