摘要
以过硫酸铵(APS)和FeCl3为复合氧化剂,采用原位化学氧化聚合法合成了导电聚3,4-乙烯二氧噻吩/聚苯胺(PEDOT/PANI)复合材料,研究了苯胺浓度及加入时间、复合氧化剂配比和复合乳化剂配比对复合材料性能的影响,并对复合材料进行了分析.结果表明,PEDOT/PANI复合材料合成的较佳工艺条件为:3,4-乙烯二氧噻(EDOT)0.6mol/L、复合氧化剂0.6mol/L(FeCl3:APS=1:2,mol)、复合乳化剂0.4mol/L(SDBS:CTAB=2:3,mol)、复合掺杂剂1.2mol/L(H2SO4:SSA=4:1,mol)及苯胺0.8mol/L,EDOT聚合2h后加入苯胺溶液继续反应8h.复合材料的导电性、结晶性和热稳定性比纯导电聚合物好.
Conductive poly(3,4-ethylene dioxythiophene)/polyaniline(PEDOT/PANI) composite was synthesized by chemical oxidative polymerization with ammonium persulfate and ferric chloride as oxidant.Its properties were studied on the effects of addition time aniline,molar ratios of FeCl3 to APS in composite oxidant and SDBS to CTAB in composite emulsifier and aniline concentration.The results show that the optimal synthesis conditions of PEDOT/PANI are:EDOT 0.6 mol/L,composite oxidant 0.6 mol/L(FeCl3:APS=1:2,mol),composite emulsifier 0.4 mol/L(SDBS:CTAB=2:3,mol),concentration of composite doping agent 1.2 mol/L(H2SO4:SSA=4:1,mol),and aniline 0.8 mol/L.After 2 h,aniline solution is added and continued to react for 8 h.PEDOT/PANI composite has better conductivity,crystalline and thermal stability than that of pure PEDOT and PANI.
