说明

聚苯胺 (PAni) 祖母绿盐可以通过 PAni 祖母绿碱 (PAni-EB) 的质子化制备。 PAni-EB 在 pH>7 时形成。一项研究解释了其对抗腐蚀剂的机制。
聚苯胺(翡翠碱)(PANI)是一种导电聚合物,由连接有氮取代衍生物的环状结构组成。它具有以碱形式存在的翠绿型氧化态。可由盐酸翠绿胺和氢氧化铵去质子化制备。主要用于电化学器件的开发。

PANI 形成可用于各种半导体应用的共轭聚合物系统。它可用于制造各种设备,包括燃料电池、发光二极管、超级电容器、化学传感器和可充电电池。
制备了 PAni-EB/聚丙烯腈 (PAN) 复合纳米纤维。研究了掺杂剂和溶剂浓度对复合材料形貌、导电性和力学性能的影响。还报道了 PAni-EB/PAN 纳米网的制备。

一般描述

Polyaniline (PAni) emeraldine salt can be prepared by protonation of PAni emeraldine base (PAni-EB). PAni-EB forms at pH>7. Its mechanism against corrosive agents has been explained in a study.
Polyaniline (emeraldine base) (PANI) is a conductive polymer which consists of a ring structure attached with nitrogen substituted derivatives. It has an emeraldine type oxidation state that exists in the form of its base. It can be prepared by deprotonation of emeraldine hydrochloric acid and ammonium hydroxide. It is mainly used in the development of electrochemical devices.
 

应用

PANI forms a conjugating polymeric system that can be used for a variety of semiconducting applications. It can be used in the fabrication of a variety of devices which include fuel cells, light emitting diodes supercapacitors, chemical sensors and rechargeable batteries.
PAni-EB/Polyacrylonitrile (PAN) composite nanofibers were fabricated. The effect of the concentration of dopant and solvent on the morphology, conductivity and mechanical properties of the composites were studied. Preparation of PAni-EB/PAN nanoweb has also been reported.
