在导电聚合物中,掺杂概念的进一步发展是基于以下的事实:樟脑磺酸(CSA)掺杂的聚苯胺(PAn)用间甲酚做溶剂比用氯仿所得膜的电导率高10~3倍,并观察到聚苯胺的首次金属行为,在178K至室温电导率随温度的升高而下降,σ_(178K)/σ_(RT)=1.1.Heeger和MacDiarmid两研究小组最近的研究表明:间甲酚可使PAn-CSA卷曲的分子链展开,并使单极化子从定域转变为离城.PAn-CSA氯仿溶液所得膜用间甲酚气氛或涂间甲酚的方法同样可改善其导电性.MacDiarmid命名此现象为2次掺杂,以区别于原掺杂的概念,其主要特征是2次掺杂过程对导电高分子主链的排列和构象产生影响,而不是以掺杂剂的存在作为提高导电性的必要条件.但至今未见对导电复合物的2次掺杂现象的进一步研究.本文成功地用现场乳液聚合方法制得导电态聚苯胺与氯磺化聚乙烯(CSPE)复合物的基础上,研究2次掺杂对其导电
A further development of the concept of doping in conducting polymers is based on the fact that CSA-doped polyaniline (PAn) has a conductivity of 10 to 3 higher than that obtained with chloroform using m-cresol as a solvent Times and the first metal behavior of polyaniline was observed and the conductivity decreased with increasing temperature from 178 K to room temperature with σ 178K / σ RT = 1.1. Recent studies by two research groups, Heeger and MacDiarmid, Cresol can unroll the curly molecular chain of PAn-CSA and make the monopole change from localized to out-of-town.The method of using m-cresol or m-cresol in the membrane of PAn-CSA chloroform can also improve its Conductivity .MacDiarmid named this phenomenon for the second doping, in order to distinguish the concept of the original doping, the main feature is the second doping process on the arrangement and the conformation of the conductive polymer backbone impact, rather than the dopant As the necessary conditions to improve the conductivity, but so far no further study on the phenomenon of secondary doping of the conductive composite has been carried out.In this paper, the conductive polyaniline and chlorosulfonated polyethylene (CSPE ) Complex based on the study of the second doping of their conduct
