Polyaniline can be made chemically or electrochemically by oxidative polymerization of the monomer aniline.The electrochemical synthesis generally yields a polyaniline film on the anode, while the chemical polymerization route can make polyaniline in bulk quantities.The classical chemical synthesis of polyaniline is carried out in solution using aniline, an oxidant, and a strong 参考资料:手翻
doping acid with either aqueous or organic solvents.By freezing the reaction bath, the polymerization can also proceed in the solid state.17,18 Since the liquid monomer aniline forms solid salts with doping acids,such as hydrochloric, sulfuric, and camphorsulfonic,
room-temperature solid-state polymerization of aniline should be possible using a solid anilinium salt as the precursor. Here, we describe a solvent-free mechanochemical route to polyaniline in which the reaction is induced by ball-milling an aniline salt and an oxidant under ambient conditions. The optical properties,molecular weight distribution, and electrical conductivity of the products are reported. The optimal molar ratio
of aniline to oxidant is determined to obtain maximum
yield. In-situ electrical resistance measurements of the
reaction mixture indicate that 1 h is sufficient for the
reaction to reach completion.

聚苯胺可以通过化学或电化学氧化聚合单体苯胺制备。
电化学合成通常在阳极产生聚苯胺膜,而化学聚合的路径可以大量制备聚苯胺。
聚苯胺的经典的化学合成可以在水溶液或者有机溶剂中进行,使用苯胺、氧化剂和掺杂强索,使用苯胺,氧化剂,和强的掺杂酸。
通过冻结反应浴,聚合也可以在固体状态下进行。17.18(可能是参考文献)
由于液态的的单体苯胺与掺杂酸,如盐酸、硫酸和樟脑磺酸,形成固态的盐,室温下固态的苯胺聚合可以用一种固态的苯胺盐(?anilinium不知道是什么意思)作为前驱体。
我们在此描述一个无溶剂的机械化学路径聚合苯胺,在环境条件下通过球磨苯胺盐和氧化剂反应。产品的光学性质、分子量分布和电导率被报道。优化苯胺和氧化物的摩尔比可以获得最大产率。
