研究了以聚(3,4-乙烯二氧噻吩)-聚苯乙烯磺酸和壳聚糖进行静电层层自组装整理,得到具有防紫外、导电功能的棉织物. 采用聚( 3 ,4-乙烯二氧噻吩) -聚苯乙烯磺酸( PE-DOT:PSS)和壳聚糖( CS)通过静电层层自组装技术对棉织物进行表面改性,并研究其导电、防紫外线性能. 采用扫描电子显微镜(SEM)、傅里叶红外分析光谱(FTIR)及表面染色色深(K/S值)分析改性棉织物的表观形态结构;采用紫外线防护系数( UPF)评估防紫外线性能,采用两探针法测量织物表面导电性能并得到相应的IV曲线. 研究表明:经石墨烯改性后的棉织物展现出超强的紫外线防护性,其导电性能也有相应的提高. 组装5次,改性织物的UPF值达到92.39 ,远高于未处理棉织物( UPF=9.37 ). 另外,仅组装5次,改性棉织物的表面电阻率由未处理棉织物的7.19 ×10 7 Ω· m降到4.4 ×10 2 Ω· m.%PEDOT:PSS and Chitosan ( CS) were utilized as functional agent to modify the surface of cotton fabric via a facile electrostatic layer-by-layer self-assembly method and the ultraviolet blocking and conductive properties of the treated fabrics were studied .The surface pattern structure of modified cotton fabric was analyzed by SEM, FTIR and K/S value;ultraviolet blocking property was assessed by adopting UPF and conductive prop-erty was measured on the surface of fabric by adopting two-probe method and IV curve was got .The studied showed that the fabric modified by graphene had excellent ultraviolet blocking property and its conductive property also increased .With 5 times assemblies , the UPF value of treated fabric was up to 92 .39 , while that of the un-treated one was just 9.37.And the electrical resistivity of the treated fabric decreased from 7.19 ×107 Ω· m to 4.4 ×102 Ω· m.
