Ferroelectric antibacterial ceramic and preparation method thereof
The preparation method comprises the following steps: firstly, preparing Na0. 5Bi0. 5TiO3 ceramic with high density, and then placing the Na0. 5Bi0. 5TiO3 ceramic in a high-voltage direct-current electric field for polarization; ferroelectric domains in the ceramic are directionally arranged through polarization of an external electric field, so that a relatively high polarization electric field is generated. Under the irradiation of simulated sunlight, the sterilization effect of the forward polarized Na < 0.5 > Bi < 0.5 > TiO < 3 > ceramic reaches 99%. The Na0. 5Bi0. 5TiO3 ferroelectric antibacterial ceramic provided by the invention is simple in preparation process, low in material cost, green and environment-friendly.
一种铁电抗菌陶瓷及其制备方法，首先制备具有高致密度的Na0.5Bi0.5TiO3陶瓷，然后将其置于高压直流电场下极化。通过外电场极化使陶瓷内的铁电畴定向排列，进而产生较高的极化电场。在模拟太阳光照射下，正向极化的Na0.5Bi0.5TiO3陶瓷的杀菌效果达到99％。本发明提供的Na0.5Bi0.5TiO3铁电抗菌陶瓷制备工艺简单，材料成本低，绿色环保。
