【摘要】 采用溶胶 -凝胶法制备TiO2 生态陶瓷。考察了溶胶浓度、有机添加剂以及涂层次数等因素对涂层质量的影响 ,并利用XRD、SEM及抗菌性能实验对其结构及性能进行了表征。结果表明 :在溶胶浓度为 0 .0 48mol·L-1,有机添加剂质量分数为 0 .112 % ,涂层次数为 3的条件下 ,所制备的TiO2 生态陶瓷具有良好的抗菌性能 ,其灭菌率达到 85 %更多还原

【Abstract】 TiO 2 ecological ceramics were prepared by sol-gel method. Some factors that effect on the performance of the coating such as concentration of collidal sol, the amount of additives and coating times were discussed.The microstructures and properties were investigated by using XRD, SEM ,and anti-bacterial experiment technology. The results indicated that TiO 2 ecological ceramics prepared had excellent anti- bacterial behavior showing 85% sterilizng effect. The optimum conditions were Ti concentration 0.048 mol·L -1 ,the amount of methyl cellulose added 0.112% weight and coating for 3 times.更多还原
