| 摘 要： | 以氯离子为掺杂阴离子,采用化学氧化法合成了聚苯胺(PAn).将PAn作为导电固定相填充到多孔陶瓷管中以制备PAn电极柱,并以此电极柱作为三电极体系中的工作电极.在电极柱上施加0.6V的负电位使PAn呈还原态,PAn中掺杂的氯离子发生脱掺杂,从而在PAn骨架上留下在三维空间上与氯离子完全匹配的空穴,即形成了“离子印迹”P...

| Abstract: | Polyaniline(PAn) was synthesized by chemical oxidation using Cl-as the doping anions,and then it was packed into a porous ceramic tube as conductive stationary phase to fabricate an electrode column which was used as the working electrode of a three-electrode system.A potential of-0.6 V was applied on the electrode column to make PAn in its reduction state,and thus Cl-was de-doped from the PAn backbone.Cavities complementary to Cl-in three dimensional space were left in PAn to form ion imprinted PAn electro... |
