The composite polyaniline-polyvinyl alcohol (PANI-PVA) is chemically synthesized by dispersion polymerization. The composite films have conductivity of the order of 10−2 S/cm. Field effect transistors (FET) on transparent sheet for two distinct PANI-PVA ratio of 1:9 and 1:11 are constructed and characterized. The steady state and transient behaviour of the device was investigated. These characteristics exhibit a p-type field-effect behaviour. The mobility, threshold voltage and transconductance of the device are also calculated.
