受限空间内化学被覆导电聚合物薄膜研究

】研究了在多孔Ta/Ta2O+阳极微孔内表面原位化学聚合聚3，4-乙烯二氧噻吩导电聚合物薄膜的制备方法，结合有机片式固体钽电解电容器等效串联电阻值的变化，对聚合过程在受限空间里的高分子链形成机理以及在弱吸附情况下微孔内的薄膜导电性能的变化进行了分析，结果表明，在受限的空间里聚合反应生成的聚合物薄膜电导率会由于受限能的影响而降低，其影响程度相似于聚合溶液浓度的变化对聚合物薄膜电导率的影响。This article investigate method of preparation in situ chemistry polymeriztion of conductive polymer poly 3,4-ethylene dioxy thiophene thin film in micropore interior surface of sinter Ta/Ta2O5 anode. The formed mechanism of macromolecule chain in restriction space as well as electrical conductivity of film in micropore interior on weak adherence occasion have been analysed with performance change of organic piece solid tantalum electrolytic capacitor. The analytic results show that, the chain length of macromolecule which polymerizing in restriction space will be changed as a result of affect of restriction energy.
