The tio2 colloidal particles are brookite nanocrystals , and the pss / ti02 films are polycrystalline films with relatively high hardness and can serve the function as reflection - enhancing coatings Pss tio _ 2薄膜为由板钛矿tio _ 2纳米晶所构成的多晶膜，硬度较高，具有增反作用。
Abstract : large quantities of spheric silver colloidal particles , which were protected by poly vinyl pyrrolidone ( pvp ) , can be converted into flake silver powders using photoinduced method 摘要：将银溶胶用适当的保护剂保护后，置于一定波长的可见光下进行辐照可以得到纳米级片状银粉。
It ' s indicated that the zeta potential and total interaction energy of the colloidal particles are both at a maximum when the nitric acid concentration is 0 . 22mol / l for the alumina sols with a mol ratio of 1 : 50 between asb and h2o , 结果表明，胶体颗粒的双电层厚度随硝酸的浓度的增加不断减小，对异丁醇铝与水的摩尔比为1 ： 50系溶胶，硝酸浓度为0 . 22mol l时胶体颗粒的zeta电位和作用位能最大。
It was found that the zeta potential and average size of the colloidal particles increase earlier and drop later with the addition of sec - buoh and both of them reach the maximal values which are 790nm and 20mv respectively when the mol ratio between sec - buoh and asb is 30 结果表明，胶体颗粒的平均粒径和zeta电位随异丁醇的增加先升高后下降，当沉积时间为1h时，异丁醇asb为40时膜的厚度最佳。
