Investigation of PEG embedded WO3-graphene thin film sensor

Abstract

In the present investigation, we demonstrated the fabrication of polyethylene glycol (PEG) embedded a WO 3-graphene film. Transparent and electrically composite films of polyethylene glycol (PEG) were fabricated on ITO coated substrate by incorporation of WO 3-graphene Nano sheets into PEG followed by spin coating and chemical reduction. The obtained film exhibited good sensitivity for H 2 and LPG gas sensing applications to be used in diverse areas.
