摘要
为研究多孔复合材料协同硅烷偶联剂改性棉织物的性能,采用溶液-溶胶法制备了活性炭负载TiO_(2)复合凝胶。通过简单的一步浸渍法将复合粒子和无氟防水剂十六烷基三甲氧基硅烷整理到棉织物表面,测试了棉织物整理前后的表面微观形貌、水接触角、表面元素组成、红外光谱、自清洁性、防污性和透气性。结果表明:改性后的棉织物表面变得粗糙,水接触角达到157°;其表面的碳、硅元素含量大幅度提升,氧元素含量减少较多,同时出现了新的元素钛;红外光谱中出现疏水性基团的强振动峰,其在水洗循环5次后水接触角仍能保持在140°。认为:改性后的棉织物达到了超疏水效果,同时具有优异的防污性和自清洁性。
In order to study properties of cotton fabric modified by porous composite material and silane coupling agent,TiO_(2) composite gel supported on activated carbon was prepared by solution-sol method.By a simple one-step impregnation process,composite particles and the fluorine-free water-repellent cetyl trimethoxysilane were treated onto the surface of the cotton fabric.Surface morphology,water contact angle,surface element composition,infrared spectrum,self-cleaning,stain resistance and air permeability of cotton fabric before and after finishing were tested. The results showed that the surface of modified cotton fabric became rough. The water contact angle was reached 157°. Carbon and silicon content on the surface of modified cotton fabric were greatly increased. Oxygen element content was greatly decreased. And a new element of Titanium was appeared at the same time. Strong vibration peaks of hydrophobic groups were seen in the FTIR spectrum.The water contact angle was remained 140°after five times washing. It is considered that the modified cotton fabric achieves superhydrophobic effect and has excellent stain resistance and self-cleaning property.
