Abstract: As a new method of polymerization, electroless polymerization was introduced to form polyaniline film on substrate of any shape. In electroless polymerization, aniline molecules were oxidized to form Pn film by soluble oxygen on the catalytic surface of Pt or Pd substrate without the supply of electric current. Similar to the mechanism of electroless plating, electroless polymerization of aniline involves local and spontaneous electrochemical reactions on only substrate.

摘要： 提出了一种新的聚合方法——无电聚合。在没有外电流的情况下，溶液中的苯胺分子在具有催化活性的铂或钯基底表面上被溶解氧氧化为聚苯胺膜。与化学镀的原理类似，苯胺的无电聚合反应过程包含阴极半反应和阳极半反应两个电化学反应。
