摘要: Two-, four-, and six-armed branched copolymers with electroactive biodegradable properties were synthesized by coupling reactions between poly(l-lactides) (PLLAs) different architecture carboxyl-capped aniline trimer (CCAT). The oligomer CCAT was prepared from amino-capped succinic anhydride. FT-IR, NMR, SEC analyses confirmed the structure of copolymers. UV−vis spectra cyclic voltammetry copolymer solution showed good properties, similar to those polyaniline. water contact angle PLLAs highest, followed undoped doped values four-armed 54−63°. Thermal polymers studied DSC TGA. had better thermal stability than pure PLLAs, Tg 48−58 °C Tm 146−177 lower PLLA counterparts. This kind biodegradab...
