Gas sensor based on polymer are sensitive to humidity. What is the reason of deterioration of polymer ( for example :polyaniline) under high humidity?
Not only polyaniline but all the polymers get deteriorate in high humidity and high temperature because polymers can not sustain for long time in high temperature due to its amorphous nature.
Is PVA useful for preventing this deterioration?
