摘要:

在水热条件下, 采用不同的钛源, 通过控制溶液碱度和冷却温度等反应条件, 利用无模板自组装技术, 在钛酸盐薄膜表面及溶液相中制备了鸟巢状和绒球状钛酸盐纳米带自组装聚集体以及海胆状钛酸盐纳米管自组装聚集体. 通过引入碳酸钠模板, 制备出形貌新颖的钛酸钠-碳酸钠香蒲状自组装聚集体复合材料. 初步研究了纳米自组装聚集体的形成机理, 认为其形成经历了一维纳米结构(纳米带或纳米管)的生长和一维纳米结构的自组装2个过程.

Abstract:

Bird's nest-like self-assembly titanate nanoribbon aggregates, fluff sphere-like self-assembly titanate nanoribbon aggregates and urchin-like self-assembly titanate nanotube aggregates were prepared without template from Ti flake(or TiO2 powder, P25) under hydrothermal conditions by adjusting NaOH concentration and cooling temperature. Cattail-like self-assembly titanate-sodium carbonate self-assembly complex aggregates were prepared with sodium carbonat as template. A possible two-stage growth mechanism involving the initial formation of primary 1D nanostructures that subsequently self-assemble was proposed. This method will provide a promising approach that the function materials are assembled into highly ordered structure in the ideal way and lend itself to the research on microdevice.

Key words: Titanate, Hydrothermal preparation, Self-assembled aggregate
