摘　　要：以亚麻和棉织物为基底材料,利用原位吸附聚合法和吸附胶团聚合法制备聚吡咯(PPy)/纤维素导电复合织物。采用SEM、FTIR、XRD和XPS研究并对比分析了两种方法制得的复合织物的表面形貌、界面结合、组织结构和元素原子数分数,并测定了表面电阻率。结果发现原位吸附聚合法在织物表面沉积的聚吡咯有一部分松散地分布于表层上,牢度较差;而添加了聚乙烯醇(PVA)的吸附胶团聚合法在织物表面沉积的聚吡咯则非常均匀、致密;两种方法制备的导电织物均为PPy与纤维素织物的复合产物,界面结合无明显差异。在复合的过程中,基底织物中的纤维素的化学结构和结晶状态未发生改变;吸附胶团聚合法中,PVA起到了模板的作用;添加PVA的吸附胶团聚合法比原位吸附聚合法所制得的复合织物的表面电阻率低,是较好的制备导电织物的方法。Conductive PPy/cellulose composite fabrics were prepared with flax and cotton as substrates using in-situ absorption polymerization （ISAP） and admicellar polymerization （AP）. Surface morphology, interface bond, structure, and element content of the composite fabrics prepared by the two methods were analyzed by SEM, FT-IR, XRD, and XPS. And the surface resistivity was measured. Results show that some PPy deposited on fabrics by ISAP disperses loosely on the surface layer. The fastness is bad. However, the PPy deposited by AP added with PVA is very uniform and compact. The conductive fabrics prepared by the two methods are all composite of PPy and cellulosic fabric and have no obvious difference in interface state. Chemical and crystalline structures of the substrate were unchanged in the course of polymerization. PVA was used as a moulding board in AP method. The surface resistivity of the composite fabric by AP is lower than that by ISAP. AP is a better method for the preparation of conductive fabrics.
