摘　　要：多功能棉织物(CO)可以进一步扩大棉织物的应用范围。本文利用正己烷和乙酸乙酯作为聚二甲基硅氧烷(PDMS)的共溶剂,并与还原氧化石墨烯(RGO)结合,制备具有抗紫外和超疏水性能的多功能棉织物(PDMS/RGO-CO),并通过改变正己烷和乙酸乙酯混合比例、棉织物浸渍共混液次数、PDMS浓度,探究最佳的制备工艺。结果表明,正己烷和乙酸乙酯体积比为7∶3、棉织物浸渍次数为2次、PDMS为100 g/L时,PDMS/RGO-CO的超疏水能力最好,接触角(CA)达到165.9°,紫外线防护系数(UPF)达到544.46。与此同时,PDMS/RGO-CO还表现出优异的防污性能和油水分离能力。Multi-functional cotton fabric(CO)can expand the application range of cotton fabric.In this paper,a multi-functional cotton fabric(PDMS/RGO-CO)with UV resistance and super hydrophobicity was prepared for the first time by combining n-hexane and ethyl acetate as the co-solvent of polydimethylsiloxane(PDMS)and reduced graphene oxide(RGO).The optimum condition was developed by changing the mixture ratio of n-hexane and ethyl acetate,impregnation times with cotton fabric immersed in RGO dispersion and PDMS concentration.The results showed that multi-functional cotton fabric(PDMS/RGO-CO)had the best super hydrophobicity when the volume ratio of n-hexane to ethyl acetate was 7∶3,the impregnation times of cotton fabric was 2 times,the PDMS concentration was 100 g/L,the contact angle(CA)was 165.9°,and the ultraviolet protection coefficient(UPF)was 544.46.At the same time,PDMS/RGO-CO also showed excellent anti-fouling performance and oil-water separation ability.
