Dear Sir, I am Narsimha Parvatikar, Research Scholar, Dept. of Physics, Gulbarga University, Gulbarga. Sir I am working on conducting polymers especially on polyaniline and polyethylene oxide with applications to batteries and sensors. Sir I have seen your biography on the net. Sir I am need of your help as I am studying some humidity sensing mechanism using polyaniline and polyethylene oxide. Sir please suggest me some of the compounds with polyaniline and polyethylene oxide to study some of the sensing mechanism. Please suggest me some of the compounds as early as possible and also the humidity sensing mechanism Thanking you Narsimha Parvatikar
