摘　　要：纤维素织物在使用过程中易受到水渍的污染,甚至还会滋生细菌。为了降低污染物对织物使用性能的影响,需要对其进行抗污染改性。本文将纤维素织物依次在多巴胺、硫酸铜溶液中进行处理,通过硼氢化钠将铜离子还原成铜单质,再将处理后的织物浸渍于十六烷基三甲氧基硅烷(Hexadecyltrimethoxysilane,HDTMS)溶液中,制备具有抗污染性能的织物。结果表明,制备的抗污染织物的接触角为155°,满足超疏水表面的要求,且对大肠杆菌(Escherichia coli,E.coli)和金黄色葡萄球菌(Staphylococcus aureus,S.aureus)的抑菌率均达到了99.9%。织物经过24h的超声处理后,仍保持稳定的抗污染性能。本文所制备的抗污染织物兼具抗水性污染和可生物降解的特点,有望拓展其在医疗卫生等领域的应用。Cellulose fabric is susceptible to water contamination and can even breed bacteria in the process of using.In order to reduce the influence of pollutants on the performance of the fabric,it is necessary to modify it for anti-pollution.In this study,the cellulose fabric is treated sequentially in dopamine and copper sulfate solution,copper ions are reduced to copper element by sodium borohydride,and the treated fabric is immersed in the hexadecyltrimethoxysilane(HDTMS)solution to prepare the fabric with anti-pollution properties.The results show that the contact angle of the resultant antipollution fabric is 155°,which meets the requirements of a superhydrophobic surface,and the antibacterial rates against both E.coli and S.aureus have reached 99.9%.After 24hof ultrasonic treatment,the fabric still maintains stable antipollution performance.The anti-pollution fabric prepared in this article has both water-resistant pollution and biodegradable characteristics,and it is expected to expand its application in the medical and health field.
