研究了聚苯胺与（苯乙烯-丁二烯）三嵌段共聚物或氯磺化聚乙烯的复合物在间甲酚二次掺杂前后电导率的变化（提高2个数量级），根据二次掺杂使聚苯胺复合物增强永久形变和断面形貌脆断结果，认为二次掺杂使卷曲的聚苯胺链展开并通过分子链间的弱相互作用而自行组成导电通路．复合物二次掺杂前后的抗张强度和伸长率变化不大，说明其主链间的弱相互作用对应力无贡献．此外，还研究了二次掺杂对复合物在中性和酸性介质中电致变色活性的影响，
The change of conductivity (increase 2 orders of magnitude) before and after secondary doping of m-cresol was studied by the complex of polyaniline with (styrene-butadiene) triblock copolymer or chlorosulfonated polyethylene. Doping makes the polyaniline composite enhance the permanent deformation and brittle fracture morphology. It is considered that the secondary doping expands the curly polyaniline chain and forms the conductive path by the weak interaction between the molecular chains. The tensile strength and elongation of the composite did not change much before and after the second doping, indicating that the weak interaction between the main chains did not contribute to the stress. In addition, the effect of secondary doping on the electrochromic activity of the composite in neutral and acidic media was also investigated.
