In order to replace the conventional tin palladium activation method, which is expensive and causes significant pollution when used to prepare conductive polyester fabric, silane coupling agents (SCAs) KH550 and KH792 are used to form self-assembly film on the surface of polyester fabric. A catalytic active center is created to initiate electroless plating after silver ions are adsorbed and reduced by formaldehyde. Finally, the conductive polyester fabric is prepared by electroless copper plating. The amount of SCAs grafted on polyester is preliminarily calculated by the reaction of ninhydrin with amino group. The copper coating with 25 % mass fraction of SCAs grows better than 20 %. Meanwhile, KH792 has a better copper plating effect than KH550 and the highest conductivity of copper-coated fabric is 1065 S/cm.

硅烷偶联剂接枝改性化学镀制备导电涤纶织物
为了替代传统的锡钯活化法制备导电涤纶织物时价格昂贵且污染严重,采用硅烷偶联剂(SCA)KH550和KH792在涤纶织物表面形成自组装膜。创建催化活性中心以在银离子后引发化学镀被甲醛吸附并还原。最后,通过化学镀铜制备导电聚酯织物。通过茚三酮与氨基的反应初步计算出接枝到聚酯上的SCA的量。SCA质量分数为25%的铜镀层生长优于20%。同时,KH792比KH550具有更好的镀铜效果,镀铜织物最高电导率达到1065S/cm。
