受限空間內(nèi)化學(xué)被覆導(dǎo)電聚合物薄膜研究

】研究了在多孔Ta/Ta2O+陽(yáng)極微孔內(nèi)表面原位化學(xué)聚合聚3，4-乙烯二氧噻吩導(dǎo)電聚合物薄膜的制備方法，結(jié)合有機(jī)片式固體鉭電解電容器等效串聯(lián)電阻值的變化，對(duì)聚合過(guò)程在受限空間里的高分子鏈形成機(jī)理以及在弱吸附情況下微孔內(nèi)的薄膜導(dǎo)電性能的變化進(jìn)行了分析，結(jié)果表明，在受限的空間里聚合反應(yīng)生成的聚合物薄膜電導(dǎo)率會(huì)由于受限能的影響而降低，其影響程度相似于聚合溶液濃度的變化對(duì)聚合物薄膜電導(dǎo)率的影響。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.
