摘要:
采用醇盐水解沉淀法制备超细纳米TiO2,平均晶粒尺寸为20 nm.通过X-射线衍射(XRD)和冷场扫描电镜(SEM)对样品的物相结构和形貌进行了表征,利用半导体测试仪Keithley 2400和精密数字电桥TH2828测试了样品在不同湿度环境下的直流伏安特性、交流电容和交流阻抗,分析其湿敏性能并讨论了湿敏机理.
Abstract:
Ultrafine nano-sized titanium dioxide is prepared by alcoholic hydrolysis precipitation method with an average grain size of 20 nm.The phase structure and morphology of the samples are characterized by X-ray diffraction(XRD)and cold field scanning electron microscopy(SEM).DC voltage-ampere characteristics,AC capacitance and AC impedance of the samples under different humidity conditions are tested by semiconductor tester Keithley 2400 and precision digital bridge TH2828.The humidity properties are analyzed and the humidity-sensing mechanism is discussed.
