The methods of co-electrospinning and surface hydrolysis have been used for improving hydrophilicity of Poly(l-lactide) (PLLA), while most of them resulted in high shrinkage and changed mechanical properties of bulk polymers. In this study, we modify PLLA electrospun scaffolds by grafting chitosan by aminolysis technology. The results showed that the amount of grafted chitosan on fibrous scaffolds...
A series of conjugated copolymers (P1 and P2-CN–P4-CN) were prepared, in which two kinds of side chains were designed: one was the repeating units similar to that of P3HT, with the aim to increase the compatible with PC 61 BM and the hole mobility; another one was the acceptor groups connected with the electron-rich backbone through the conjugated 3,4-ethylenedioxythiophene bridge, in order...
