1、工藝制備的復(fù)合導(dǎo)電織物的K／S值較大，說明聚苯胺吸附量較高；復(fù)合導(dǎo)電織物的力學(xué)性能改變不大；經(jīng)超聲洗滌5次后，表面電阻率仍可穩(wěn)定在0．89KQ；具有一定的電磁屏蔽效能。關(guān)鍵詞：低溫等離子；聚苯胺；原位聚合；導(dǎo)電織物PreparationandPropertyStudy0fPolyaniline／PolyesterCompositeConductiveFabricAbstractPolyanilineshowsattractiveprospectsinmanyrespects，easytoprepare，cheaprawmaterial，hi．gllconductivity，e
