Research on humidity sensing properties of pan-poly-vanadium-molybdenum acid nanocomposites

LI Li1,WANG Bao-hui1,TONG Mao-song2(1.School of Chemistry and Chemical Engineering,Daqing Petroleum Institute,Daqing 163318,China;2.R&D Center of Well Logging Company,Daqing Petroleum Administrative Bureau,Daqing 163412,China)  
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 ℃,and it is a new humidity sensing material.
