以两嵌段共聚物聚氧化乙烷-b-聚丙烯酸叔丁酯(PEO-b-Pt BA)及其水解产物聚氧化乙烷-b-聚丙烯酸(PEO-b-PAA)为模板制备了亚微米至纳米级棒状聚联苯胺(PBz)颗粒。利用红外光谱、核磁共振、透射电镜及循环伏安和交流阻抗等测试了PBz的结构、形貌和电化学性能。结果表明,嵌段共聚物为模板合成的PBz呈现棒状分布,颗粒直径均小于200 nm且部分在100 nm以内。PBz颗粒形貌均匀,尺寸均一,使用有机溶剂溶解嵌段共聚物模板未对PBz颗粒形貌产生影响。不同模板合成的PBz均具有一定的电化学活性,以PEO-b-PAA为模板得到的各样品电化学性能优于PEO-b-Pt BA为模板的情况。在电流密度为1 A/g时,材料比电容最高达到了263 F/g。
Poly (ethylene oxide) -b-poly (t-butyl acrylate) (PEO-b-Pt BA) and its hydrolyzate polyoxyethylene -b-polyacrylic acid (PEO-b-PAA) Submicron to nanometer scale rod polybenzidine (PBz) particles. The structure, morphology and electrochemical properties of PBz were tested by infrared spectroscopy, nuclear magnetic resonance, transmission electron microscopy, cyclic voltammetry and AC impedance. The results showed that the PBz synthesized by the block copolymers exhibited rod-like distribution with particle diameters less than 200 nm and partially within 100 nm. The morphology of PBz particles is uniform and the size is uniform. The use of organic solvent to dissolve the block copolymer template did not affect the morphology of PBz particles. The PBz synthesized by different templates has certain electrochemical activity. The electrochemical performance of each sample obtained with PEO-b-PAA is better than that of PEO-b-Pt BA. At a current density of 1 A / g, the highest specific capacitance of the material reached 263 F / g.
