Hybrid Film of Chemically Modified PEDOT: PSS-Graphene Oxide for Chemical Sensing Applications

A hybrid of graphene and conducting polymer are an excellent candidate as the sensing materials for chemical sensor application. In this work, a hybrid thin film of graphene oxide (GO) and poly (3, 4-ethylenedioxythiophene): poly (styrene sulfonate) (PEDOT: PSS) was prepared and has been used as active material for chemical sensors. The chemical sensors based on hybrid film of PEDOT: PSS-GO are capable of detecting electrical signals caused by the absorption of trace levels of different analyte vapors with high sensitivity
