摘要
在无任何外加添加剂的情况下,于盐酸介质中,通过苯胺(AN)与二苯胺磺酸(DPS)的化学氧化聚合制备了纳米结构导电磺化苯胺共聚物(PANDPS)。研究了聚合条件对共聚物粒径和形貌的影响。结果表明,共聚物颗粒的大小和形貌随聚合条件的变化而变化,在AN/DPS摩尔比为50/50、单体浓度为0.2 mol/L、过硫酸铵/单体摩尔比为1/4、1.0 mol/L盐酸水溶液中25℃反应24 h,可以获得平均粒径为33 nm的共聚物纳米颗粒;而当单体浓度为0.1 mol/L,聚合反应72 h,其它聚合条件相同时则得到直径为130 nm^140 nm、长440 nm^1.35μm的共聚物纳米棒。
Nanostructural electroconductive poly（aniline-eo-diphenylamine4-sulfonate） （PANDPS） nanoparticles with good self-stability were synthesized by chemical oxidative polymerization of aniline （AN） with diphenylamine4-sulfonate （DPS） in HCl aqueous medium without any external additive. The variation of the structure of the copolymers was studied by changing the monomer ratio, oxidant/ monomer molar ratio and polymerization time. It is found that the particle size and structure of the copolymers varies with the polymerization conditions. The PANDPS（50/50） copolymer nanoparticles with the average diameter of 33nm were synthesized with a monomer concentration of 0.2 mol/L, （NH4）2S2Os/monomer ratio of 1/4 in 1.0 mol/L HC1 at 25 ℃ for 24 h, whereas copolymer nanorods （130 nm～140 nm in diameter and 440 nm～1.35 μm in length） were obtained during the polymerization with a monomer concentration of 0.1 mol/L, （NH4）2S2O8/monomer molar ratio of 1/4 in 1.0 mol/L HCl at 25 ℃ for 72 h.
