Al_2O_3涂敷TiO_2纳米晶粒的制备及其抗絮凝性研究

Preparation of Al 2O 3 Coated TiO 2 Nanocrystals and Investigation of Its Antiflocculation

纳米材料特异性能的开发与利用，是当今纳米材料科学研究中的热点之一．国外新近报道了［１～３］ＴｉＯ２纳米晶粒在光学增益体系中的一种新应用．据报道，将ＴｉＯ２纳米晶粒散布到染料罗丹明过氯酸盐的甲醇溶液中，在Ｎｄ∶ＹＡＧ５３２ｎｍ激光激发下，产生出奇特的光...

The effects of temperature and pressure on the preparation of Al 2O 3 coated TiO 2 nanocrystals as well as its antiflocculation were investigated in this paper. The experimental result reveals that the coating process has greatly improved the antiflocculation of TiO 2 nanocrystals in the solvent of ethanol, however, temperature and pressure have little different effect on it.
