摘　　要：通过溶胶-凝胶法制备纳米TiO2粉末,产品用XRD和TEM进行表征;用3种改性方法对所制备的纳米TiO2粉末进行改性,对改性后的产品进行红外光谱测试和接触角的测试,分析比较3种改性方法的效果,并用改性后的纳米TiO2粉末与氟碳乳液配制成涂料,观察涂膜的微观结构,分析比较3种改性产品的实际应用效果。The title nano TiO_2 has been prepared by use of sol-geo technology, which is further modified by use of three approaches and characterized by XRD and TEM. The modified products are measured using infrared spectrum and contact angle test. The three different modification approaches are evaluated. The modified nano TiO_2 is formulated with fluorocarbon emulsion into coatings. The microstructures of the coatings film are viewed. The practical application effects for the three modified products in coatings are compared and evaluated.
