摘要

摘要采用开环聚合和原子转移自由基聚合相结合的方法合成了四臂星形聚(ε-己内酯)-b-聚(2-羟乙基甲基丙烯酸酯)。所得共聚物的结构通过傅里叶变换红外光谱、1H和13C核磁共振光谱进行了表征。采用静电纺丝技术制备了四臂星形聚(ε-己内酯)-聚(2-甲基丙烯酸羟乙酯)共聚物与聚苯胺共混的均匀电活性纳米纤维。采用循环伏安法对制备的纳米纤维的电活性进行了研究。用扫描电镜研究了四臂星形聚(ε-己内酯)-b-聚(2-羟乙基甲基丙烯酸酯)及其与聚苯胺共混物制备的静电纺丝纳米纤维的形貌。聚苯胺的存在使粘丝明显减少。图形抽象

Preparation of Electrospun Electroactive Nanofibers of Four Arm Star-Shaped Poly(ε-Caprolactone)-b-Poly(2-Hydroxyethyl Methacrylate) and Its Blends with Polyaniline

ABSTRACT A combination of ring-opening polymerization and atom-transfer radical polymerization was used to synthesize a four-arm star-shaped poly(ε-caprolactone)-b-poly(2-hydroxyethyl methacrylate). The structure of obtained copolymer was determined by Fourier transform infrared, 1H and 13C NMR spectroscopies. The uniform electroactive nanofibers consisting blend of four-arm star-shaped poly(ε-caprolactone)-b-poly(2-hydroxyethyl methacrylate) copolymer and polyaniline were produced using electrospinning technique. The electroactivity of prepared nanofibers was investigated using cyclic voltammetry measurement. The morphologies of electrospun nanofibers produced from four-arm star-shaped poly(ε-caprolactone)-b-poly(2-hydroxyethyl methacrylate) and their blends with polyaniline were investigated by the scanning electron microscopy. The presence of polyaniline resulted in significant decrease of sticking fibers. GRAPHICAL ABSTRACT
