    • The present invention provides a process for producing a metal nanoparticle composite film, which is capable of independently controlling the particle diameter and the volume filling ratio of metal nanoparticles in the metal nanoparticle composite film. The process comprises the steps of (a) treating a polyimide resin film with an alkali aqueous solution to thereby introduce a carboxyl group, (b) bringing the resin film into contact with a solution containing metal ions, to thereby dope the metal ions in the resin film, and (c) performing thermal reduction treatment in a reducing gas, thereby producing the metal nanoparticle composite film containing the metal nanoparticles dispersed in the polyimide resin film, wherein the volume filling ratio of the metal nanoparticles in the composite film is controlled by regulating the thickness of a nanoparticle dispersed layer formed in the polyimide resin film with the thermal reduction treatment in the reducing gas in the step (c).
    • 本发明提供一种能够独立地控制金属纳米粒子复合膜中的金属纳米粒子的粒径和体积填充率的金属纳米粒子复合膜的制造方法。 该方法包括以下步骤:(a)用碱水溶液处理聚酰亚胺树脂膜,从而引入羧基,(b)使树脂膜与含有金属离子的溶液接触,从而将金属离子掺入 树脂膜,(c)在还原气体中进行热还原处理,由此制造含有分散在聚酰亚胺树脂膜中的金属纳米粒子的金属纳米粒子复合膜,其中复合膜中的金属纳米粒子的体积填充率由 通过步骤(c)中的还原气体中的热还原处理来调节在聚酰亚胺树脂膜中形成的纳米粒子分散层的厚度。
