聚苯胺-复合钒钼酸纳米复合材料的湿敏特性研究
摘要
采用原位氧化聚合法制备了聚苯胺—复合钒钼酸纳米复合材料
并对其进行了XRD表征和湿敏特性研究。结果表明:聚苯胺插入复合钒钼酸层间
当An∶H2V10Mo2O31±y=1/2∶1时
湿敏性能最好
在工作频率为1 kHz
温度为20℃的条件下
PAn-H2V10Mo2O31±y湿敏元件在全湿度范围内线性好、灵敏度高
是一种很有前途的新型湿敏材料。
Abstract
Polyaniline can be inserted in poly-vanadium-molybdenum acid xerogel by in situ oxidative polymerization to produce PAn-H2V10Mo2O31±ynamocomposites.The XRD investigations indicate that the polyaniline is intercalated into the H2V10Mo2O31±yframework.The humidity sensing properties of PAn-H2V10Mo2O31±ynamocomposites are the best when An∶H2V10Mo2O31±y=1/2∶1 and it has high sensitivity
better linear in total humidity range at the condition of 1 kHz and 20 ℃
