采用静态聚合法,以过硫酸铵为氧化剂,使苯胺与吡咯进行共聚,制备了高产率(88%)的纳米结构苯胺/吡咯(PANPY)共聚物。研究结果发现,苯胺/吡咯摩尔比和聚合介质对共聚物的形貌有重大影响。以1.0 mol/L盐酸溶液为介质,苯胺/吡咯摩尔比为90/10时,可制得直径为70 nm～90 nm、长为1.3μm的共聚物纳米纤维;苯胺/吡咯摩尔比为50/50时,得到平均粒径约为400 nm的杨梅球状共聚物颗粒,透射电子显微镜的结果表明这些杨梅球状共聚物颗粒是由直径为5nm,长25nm的共聚物微小纳米纤维自组装而成。而以0.1 mol/L NaOH水溶液为反应介质,则可以得到外直径为1.8μm～2.6μm的自组装共聚物微球。
Ammonia and pyrrole were copolymerized with ammonium persulfate as oxidant by static polymerization method to prepare nano-structured aniline / pyrrole (PANPY) copolymer with high yield (88%). The results showed that the aniline / pyrrole molar ratio and the polymerization medium had a significant effect on the morphology of the copolymer. When the molar ratio of aniline / pyrrole was 90/10, the copolymer nanofibers with diameter of 70 nm-90 nm and length of 1.3 μm could be obtained by using 1.0 mol / L hydrochloric acid solution as the medium. The aniline / pyrrole molar ratio was 50 / 50, the average particle size of about 400 nm Baymeat spherical copolymer particles obtained by transmission electron microscopy results show that these Bayberry spherical copolymer particles by the diameter of 5nm, 25nm length of the copolymer micro-nanofibers self-assembled. With 0.1 mol / L NaOH aqueous solution as the reaction medium, self-assembled copolymer microspheres with outer diameter of 1.8μm ~ 2.6μm can be obtained.
