聚(3,4-乙烯二氧噻吩)/棉复合织物的制备及性能

Preparation and properties of poly(3,4-ethylenedioxythiophene)/cotton composite conductive fabrics

以棉布为基材、噻吩为单体,用浸渍烘干法和原位聚合法制得聚(3,4-乙烯二氧噻吩)(PEDOT)/棉复合织物。测试导电织物的表面结构、耐摩擦性能、耐洗涤性能和热稳定性,得出最佳制备工艺:20℃,过硫酸铵0.05 mol/L,三氯化铁0.1 mol/L,3,4-乙烯二氧噻吩0.1 mol/L,聚苯乙烯磺酸钠10 g/L。与浸渍烘干法相比,原位聚合法制备的复合织物中聚噻吩与棉纤维结合更牢固,导电性能良好。采用电阻率计和表面电阻仪测试织物方阻,并比较两种测试方法。结果表明:当方阻小于5.0×10^(4)Ω/sq时,两种测试方法的结果相近。

Poly(3,4-ethylenedioxythiophene)(PEDOT)/cotton conductive fabrics was prepared by dipping and drying method and in-situ polymerization method using cotton as the substrate and thiophene as monomers.The surface structure,friction resistance,washing resistance and thermal stability of the conductive fabric were tested,and the optimum preparation process of fabric preparation were obtained as follows:20℃,ammonium persulfate 0.05 mol/L,ferric chloride 0.1 mol/L,3,4-ethylenedioxythiophene 0.1 mol/L,sodium polystyrene sulfonate 10 g/L.Compared with the immersion drying method,the combination of polythiophene and cotton fiber was stronger in composite fabric prepared by in-situ polymerization,and the conductivity was good.In addition,the square resistance of the fabric was tested by resistivity meter and surface resistance meter,and the two methods were compared.The results demonstrated that when the square resistance was less than 5.0×10^(4)Ω/sq,the results of the two test methods were similar.
