以机械活化固相法制备的醋酸丁酸纤维素(CAB)为基底,充分溶解后与苯胺均匀混合,以过硫酸铵为氧化剂,盐酸为掺杂剂,采用原位聚合法制得聚苯胺(PANI)/CAB(PANI/CAB)导电复合膜。探讨苯胺加入量、过硫酸铵与苯胺摩尔配合比、盐酸浓度以及反应时间对导电复合膜导电性能的影响,研究结果表明:CAB用量0.5g,苯胺单体加入量1.25g,过硫酸铵与苯胺摩尔配合比为1∶1,盐酸浓度1.5mol/L,反应时间11h条件下,制得的PANI/CAB导电复合膜的导电性最好,电导率达到0.255S/cm。
Cellulose acetate butyrate (CAB) prepared by mechanical activation-assisted solid phase synthesis was used as substrate,which was dissolved in acetone and uniformly mixed with aniline,and then polyaniline (PANI)/CAB (PANI/CAB) conductive composite films were prepared by in-situ polymerization with ammonium persulphate (APS) as oxidizing agent and HCl as doping agent.The effects of aniline dosage,molar ratio of APS and aniline,HCl concentration,and reaction time on the conductivity of PANI/CAB were investigated.The results showed that under the conditions of fixed CAB dosage 0.5g,aniline dosage 1.25g,molar ratio of APS and aniline 1∶1,HCl concentration 1.5mol/L,reaction time 11h,the electroconductivity of PANI/CAB was best,with the conductivity of 0.255S/cm.
