Ionic polymer metal composites (IPMC) can be used as actuators and sensors and intrinsically havelow activation voltage and large bending strain, which help to transform electrical energy to mechanicalenergy and can be utilized as bidirectional material. In this study, the ionic polymeric blendfilms/membranes of PVDF:PSSS:PVP in the blend ratio of 40:30:30; 50:30:20 and 60:15:25 (wt.%)is presented. The membranes were prepared by solution cast technique and coated with grapheneoxide (GO)-polyaniline (PANI). Membranes were characterized by X-ray diffraction, opticalmicroscopy. Electrical conductivities at different frequencies and water uptake properties were alsodetermined. The actuating performance of PVDF:PSSS:PVP and water uptake of blend membranewas found to be maximum for the blend ratio of 60:15:25. PVDF:PSSS:PVP with blend ratio (60:15:25)also exhibited highest actuation at 10 V DC. Graphene oxide was prepared and characterized by usingFTIR and Raman spectra. A brief account of the fabrication of IPMC and its actuation application wasalso presented.
