摘　　要：采用羧基改性纤维素纳米晶(CNC)与纳米氧化锌(ZnO)制备CNC/ZnO复合材料,并将其与聚二甲基硅氧烷(PDMS)一起用于棉织物整理,制备具有超疏水防紫外线功能的棉织物(CNC/ZnO/PDMS@棉织物)。测试了整理棉织物的结构、形貌及超疏水防紫外线性能。结果表明:CNC/ZnO复合材料已成功整理至棉织物上,并构建了微观粗糙结构,其整理棉织物的水滴接触角为154°,对常见液滴如水滴、可乐、果汁、牛奶等实现了优异的拒水防污性能,同时其紫外线防护系数(UPF)大于40,UVA及UVB透过率均小于5%,实现了超疏水防紫外线效果。整理棉织物还具有一定的耐摩擦性和耐紫外光照射稳定性。CNC/ZnO composites are prepared by compositing carboxylic cellulose nanocrystals(CNC)with na⁃no-zinc oxide(ZnO).CNC/ZnO/PDMS@cotton fabrics with superhydrophobicity and UV protection are pre⁃pared by coating CNC/ZnO and polydimethylsiloxane(PDMS).The structure,morphology,superhydrophobic property and UV protection performance of CNC/ZnO/PDMS@cotton fabrics are determined.The results show that CNC/ZnO composite are successfully coated onto cotton fabrics and constructed microscopic rough struc⁃ture.The water contact angle of the treated cotton fabrics is 154°.The ultraviolet protection factor(UPF)of treated cotton fabric is over 40,and the UVA and UVB transmittances are less than 5%.Excellent water repel⁃lent and anti-fouling performance have been achieved for common liquid droplets such as water,cola,juice,milk,etc.The obtained CNC/ZnO/PDMS@cotton fabrics have excellent superhydrophobic and UV-blocking property,as well as good resistance to rubbing and UV irradiation.
