用户论文(2005)：玻璃表面功能薄膜的制备与性能研究

【中文摘要】 玻璃表面改性技术在工农业、医学、天文学、军事和日常生活等领域中有着非常广阔的应用前景。本研究旨在研制出玻璃表面可以同时满足隔热、保温及采光的要求又具有防雨水、自清洁或亲水、光催化和防雾等功能的薄膜。在玻璃基板上分别制备了SnO2:F+Sb、疏水、亲水薄膜,并采用喷雾热分解法与溶胶凝胶法相结合,制备了 SnO2:F+Sb/疏水(亲水)功能多层膜,对比分析了单层薄膜与多层薄膜的各种性能。进一步采用原子力显微镜、扫描电镜、X射线衍射仪和红外光谱仪、紫外-可见光光度仪等研究了薄膜制备工艺、结构、成分及各种因素对薄膜性能的影响。结论如下: (1) 采用溶胶凝胶法,制备了具有特殊表面形态的无机Al2O3薄膜,合成了低表面能的三甲基硅氧烷和氟硅烷有机物,并采用无机有机结合的方法,制备出疏水薄膜,其表面接触角最高可达156°,并通过控制薄膜制备工艺,使薄膜在保持较好疏水特性的同时具有较高的可见光透过率。 (2) 在玻璃基体上制备了TiO2/SiO2复合亲水薄膜,得到的表面接触角为0°, 可以在黑暗中维持四天,达到超亲水特性。薄膜具有较高的光催化活性,在水蒸气环境下,涂覆有TiO2/... 【英文摘要】 The surface modification of the glass holds great promise for applications in industry, agriculture, iatrology, astronomy, military affairs, ordinary life and so on. In this paper the films that can meet the desire of heat insulation, heat preservation and lighting, at the same time, it possess the function of hydrophobic, self-cleaning or hydrophilic, photocatalysis, anti-fog on glass surface were expected to be prepared. The films of SnO2:F+Sb, hydrophobic, hydrophilic were prepared on glass substrate. Th...
