So it has great application prospect in many aspects of advanced polymer materials, coatings, cosmetics, cultural relic protection, which has aroused great concern. However, the vast majority of rutile TiO2 nanoparticles preparation cannot do without high temperature, high temperature and hard agglomeration often caused by nano particles, which required for the subsequent use of the process of dispersing inconvenience. In the literature reported that the reported synthesis method of rutile nano crystal at room temperature only a few, but they consume a lot of alcohol or acid [2 ~ 4] [5], sometimes it takes a long time aging [6]. High resolution transmission electron microscopy has a very important application in the research of nano [7] crystal structure, interface structure, defects and [8] motion [9] and conversion of amorphous and nanocrystalline [10]. At present it has been reported that the morphology of [11] anatase nanocrystals were studied by HRTEM, but the structure of rutile nanocrystals and the interface has not been reported
使它在高级涂料、化妆品、高分子材料、文物保护等诸多方面有巨大的应用前景,因而引起了人们的极大关注。然而迄今为止,绝大多数纳米金红石型TiO2的制备都离不开高温过程,而高温往往会造成纳米颗粒的硬团聚,这为后续使用过程所需的分散带来了不便。在有文献的报道中,仅有几种室温下合成金红石型纳米晶体的方法报道,但都消耗了大量的酸[2～4]或乙醇[5],有时还需要较长的时间陈化[6]。 高分辨率透射电镜在研究纳米晶体结构[7]、界面结构[8]、缺 陷及其运动[9]以及非晶与纳米晶体的转换[10] 中有着非常重要的应用。目前已有文献报道用HRTEM研究了锐钛矿纳米晶体的形貌[11],但对于金红石型纳米晶的结构以及界面情况还未见报道
