【摘要】 以玻璃纤维为基体,钛酸丁酯为原料,采用溶胶-凝胶和水热处理技术,在玻璃纤维表面制备了TiO₂多级结构,并利用XRD和SEM研究了水热处理不同时间的玻璃纤维表面TiO₂微纳米结构形态,结果表明随着水热处理时间的延长,金红石相TiO₂棒状簇晶可以完全覆盖在玻璃纤维表面,并形成由微米和纳米级TiO₂棒晶交错构筑的微纳米多级结构。更多还原

【Abstract】 TiO₂ micro/nano architecture was prepared on the surface of glass fibers via a sol-gel and hydrothermal process using tetrabutyl titanate as raw materials.The phase and morphology of the products were characterized by XRD and SEM.The results indicated that rutile TiO₂ rod crystals in form of radial clusters could cover the surface of glass fibers completely with the prolonged treated time under hydrothermal conditions.The micro and nano TiO₂ rod crystals in the crystal clusters intersect each other to form the micro/nano architecture on the surface of glass fibers.更多还原
