长链烷基化合物对聚苯胺电导率影响的研究

摘要

Mixing polyanline ,Dodecylbenzenesulfonate (referred DBSA) form ion-doped polyaniline poly‐aniline (referred PADB) .In emulsion polymerization resulting product PADB because it contains an exces‐sive amount of DBSA .Before and after cleaning ,we found (pole /di-pole) maximum absorption wave‐length shift is not the same .Acetoneλmax PADB were around 775 and 878nm .Excess of the long -chain alkyl compound is disadvantageous for PADB stretch ,thereby reducing the degree of conductivity ,when the amount of PSS (Polystyrene sulfonate) is less than 10% ,we find (pole /di -pole) transfer of the maximum absorption wavelength red shift ,blue shift when the amount was higher than 10% PSS .%十二烷基苯磺酸（简称DBSA）掺杂聚苯胺形成离子性聚苯胺（简称PADB）。以乳化聚合所得的产物PADB因含有过量的 DBSA 。在清洗前后，发现（极子／双极子）转移的最大吸收波长并不一样。丙酮清洗 PADB前后的λmax 分别为775 nm及878 nm 。过量的长链烷基化合物对 PADB 的伸展是不利的，因而降低电导率数，当PSS（聚苯乙烯磺酸）的量低于10％，发现（极子／双极子）转移的最大吸收波长为红移，当PSS的量高于10％时则为蓝移。
