摘　　要：采用模板法在铜叉指电极上制备了多孔氧化钛/聚苯乙烯磺酸钠(多孔TiO2/NaPSS)复合湿敏材料。并采用扫描电镜(SEM)对其微观结构进行表征分析,LCR数字电桥对其湿敏特性进行测试分析。结果表明,相对于NaPSS和TiO2/NaPSS两种湿敏材料而言,多孔TiO2/NaPSS复合湿敏材料具有更低的阻抗值及湿滞差,较好的线性关系,其响应速度更快,重复稳定性更高,在湿度传感器方面具有广阔的应用前景。The template method was adopted to produce porous titanium oxide/polystyrene sulfonate sodium (porous TiO2/NaPSS) composite humidity-sensitive material on the copper interdigital electrode.Meanwhile, the scanning electron microscope (SEM) was used for investigating the microstructure, and the LCR digital bridge was used for analyzing humidity-sensitive characterization.The result shows that the porous TiO2/NaPSS composite humidity-sensitive material has lower impedance value, lower humidity hysteresis, and better linearity than that of NaPSS and TiO2/NaPSS humidity-sensitive materials.The response rate is accelerated and the repeated stability of porous TiO2/NaPSS is obviously improved.Therefore, porous TiO2/NaPSS composite humidity material has wide application prospect in the field of humidity sensor.
