| 摘 要： | 以水合Al2O3为改性剂对TiO2粉体进行表面改性,并以六偏磷酸钠、硅酸钠为分散剂对纳米二氧化钛分散的最佳条件进行了摸索。同时采用分光光度法研究了乙二醇、聚丙烯酸钠在不同条件下对表面改性后的TiO2在水溶液中的分散效果。并对其分散的稳定性及抗菌性能进行了初步的探讨。结果表明:经氧化铝改性的二氧化钛在乙二醇、聚丙烯酸钠的水溶液中均具有良好的稳定性,并具有一定的抗菌性能。

| Abstract: | Hydrated Al2O3 was used as modifier for the surface - modification of TiO2 powder. The condition of the dispersing of nano - TiO2 in (NaPO3)6 and Na2SiO3 was studied. The spectrophotometry method was used to determine the effects of ethylene glycol, sodium polyacrylate on the dispersion of titanium dioxide in aqueous solution. It was studied initially that the dispersive stability of TiO2 and antibacterial capability. The results showed that ethylene glycol and sodium polyacrylate were effective dispersants for TiO2 in aqueous solution. The dispersive nanotitanium dioxide had antibacterial capability. |
