【摘要】 纳米二氧化钛在20世纪80年代开始进入人们的视线,因具有优良的性能而有着广阔的应用前景。但纳米二氧化钛的粉体粒度很小,比表面积很大,极易自发团聚,最终导致性能下降;并且纳米粉体的存储和使用也是一大问题。为了解决这些问题,制备稳定均匀的纳米二氧化钛分散液成为研究热点。本文综述了关于制备稳定的纳米二氧化钛分散液的研究进展,系统介绍了纳米二氧化钛分散液的制备方法、保持稳定的方法和表征方法,并总结了纳米二氧化钛分散液面临的主要问题,展望了其未来的发展前景。更多还原

【Abstract】 Nano-titanium dioxide began to enter people’s sights in the 1980s, and has broad application prospects because of its excellent performance. However, the nano-titanium dioxide has a small particle size and a large specific surface area, so it is easily agglomerated spontaneously, which eventually leads to the decline of performance. And the inconvenience of the nano-powder in storage and use is also a big problem. In order to solve these problems, preparation of a stable uniform nano-titanium dioxide dispersion has become a research hotspot. In this paper, the research progress of preparation of stable nanometer titanium dioxide dispersion is reviewed. The preparation method, retention stability method and characterization method of nanometer titanium dioxide dispersion are introduced systematically. Finally, the main problems faced by nano-titanium dioxide dispersion and the prospect of its future development are summarized.更多还原
