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

使它在高級涂料、化妝品、高分子材料、文物保護等諸多方面有巨大的應用前景,因而引起了人們的極大關注。然而迄今為止,絕大多數納米金紅石型TiO2的制備都離不開高溫過程,而高溫往往會造成納米顆粒的硬團聚,這為后續使用過程所需的分散帶來了不便。在有文獻的報道中,僅有幾種室溫下合成金紅石型納米晶體的方法報道,但都消耗了 的酸[2~4]或乙醇[5],有時還需要較長的時間陳化[6]。 高分辨率透射電鏡在研究納米晶體結構[7]、界面結構[8]、缺 陷及其運動[9]以及非晶與納米晶體的轉換[10] 中有著非常重要的應用。目前已有文獻報道用HRTEM研究了銳鈦礦納米晶體的形貌[11],但對于金紅石型納米晶的結構以及界面情況還未見報道
