Hydrophobic silica ( SiO_2) aerogels were prepared from cheap water glass, directly modified with surface modifier of hexamethyldisiloxane/ trimethylchlorosilane ( HMDSO/ TMCS) without solvent exchange and via ambient drying. 以价廉的水玻璃为原料,通过六甲基二硅氧烷和三甲基氯硅烷混合改性剂对制备的SiO2水凝胶进行表面改性,避免了溶剂交换,并常压干燥得到疏水的SiO2气凝胶。
The processing parameters, such as the ICP input power, the working pressure, the rate of Ar and HMDSO and deposition time, remarkably affect the chemical structures and properties. 2. 沉积的工艺参数对薄膜结构和性能有一定的影响,如ICP源输入功率、工作气压、Ar与单体的流量比、沉积时间等。
