摘　　要：以正硅酸乙酯(TEOS)、十六烷基三甲氧基硅烷(HDTMS)为前驱体,采用一步St?ber法在纤维表面负载疏水性纳米SiO_2。通过调控TEOS、HDTMS和氨水用量以及反应时间,在涤纶织物表面构筑微纳双阶粗糙结构,结合HDTMS的疏水化作用,获得具有超疏水和防水透气性的多功能织物。测定了织物的耐水压性能、表面形貌、表面润湿性,以及超疏水的稳定性等。结果表明:改性后织物表面的水滴接触角为162°,可承受8 044 Pa的静水压,并且具有优异的耐紫外光稳定性和耐酸碱稳定性。The hydrophobic nano-SiO2 is loaded on the surface of the fiber by one step Stober method using tetraethoxysilane （TEOS） and hexadecyltrimethoxysilane （HDTMS） as the precursor. The micro-nano double-order rough structure on the surface of polyester fabric is constructed by adjusting the dosage of TEOS, HDTMS and ammonia, as well as the reaction time. Super hydrophobic and breathable functional fabric is obtained with the hydrophobic effect of HDTMS. The permeability of the fabric is tested by hydrostatic pressure tester. The surface morphology of the fabric is observed by scanning electron microscopy. The wettability of the fabric is measured by video optical contact angle instrument. The water proof and super hydrophobic stability are studied. The results show that the modified fabric features 162° of the water contact angle, 8 044 Pa of hydrostatic pressure, and has excellent UV stability and acid- and alkali- stability.
