摘　　要：以乙烯基三甲氧基硅烷(VTMS)和二乙烯基苯(DVB)为原料,通过溶剂热合成有机框架P(DVB-VTMS)对棉织物进行表面接枝改性,以实现棉织物的超疏水功能化。采用接触角、SEM、UV、XPS和FTIR测试研究溶剂配比对织物表面浸润性能、微观形貌与化学成分的影响。结果表明,VTMS∶DVB质量比为1∶4时,改性织物的接触角为169.32°,滚动角为5°,经过500次磨损和24 h酸碱腐蚀后仍可维持织物的超疏水性能;接枝改性处理对棉织物的透气性、拉伸断裂性能无明显影响。Using vinyltrimethoxysilane(VTMS)and divinylbenzene(DVB)as raw materials,the surface of cotton fabric is grafted and modified by solvothermal copolymerization of covalent organic framework P(DVB-VTMS)to realize superhydrophobic functionalization.The influence of sis studied.The results show that when the optimum mass ratio of VTMS∶DVB is 1∶4,the contact angle of the modified fabric is 169.32°,meanwhile the rolling angle is 5°.After 500 times abrasion and 24 hours acid-base corrosion,the graft modification treatment has no obvious effect on the air permeability and tensile fracture performance of the cotton fabric.
