摘　　要：采用浸渍法以纳米TiO2和月桂酸对棉纤维进行表面改性,制备抗紫外线自清洁超疏水棉布,其水接触角高达156°。改性后的超疏水棉布残余量是原始棉布残余量的2.5倍,并可抵挡96.4%以上的紫外线。改性后的棉布采用砂纸进行500次摩擦试验后,其表面水接触角仍高达151°。在高温、强腐蚀等苛刻环境下,超疏水棉布表面水接触角保持在138°以上。With the development of functional cotton fabrics and wearable devices,the preparation of superhydrophobic,self-cleaning,UV-blocking and robust cotton fabric is attracted great attention by researchers. The research adopts the dipping method with nanometer TiO 2 and lauric acid which were coated on the cotton fiber surface. The water contact angle of superhydrophobic cotton fabric was up to 156°. The superhydrophobic cotton fabric was characterized by TGA,the weight-loss ratio value of the modified cotton fabric was 2.5 times that of the original cotton fabric. The superhydrophobic cotton fabric was characterized by UV,compared with the original cotton fabric can withstand more than 96.4% of the ultraviolet radiation. The water contact angle of modified cotton fabric surface was still as high as 151° after 500 times friction test by sandpaper. In addition,the water contact angle of modified cotton fabric surface was still as high as 138° under high temperature,strong corrosion and other harsh environment.
