Graphene Oxide–Doped PVDF/PSSA/PVP Polymer Blend Polymer Thin Film for Actuation Application

PVDF/PSSA/PVP blend membrane in the blend ratio of 60/15/25 and 50/30/20 are prepared by solution cast technique. The actuating performance of PVSD/PSSA/PVP 60/15/25 and water uptake (WUP) of blend membrane is found to be higher than blend ratio of 50/30/20. PVDF/PSSA/PVP 60/15/25 characterized by different techniques such as XRD, SEM, FTIR, and electrical conductivity is determined at different frequencies. Ionic–polymer composite (IPC) actuator displays continuously large actuation displacement without back relaxation and with large blocking force at direct current (DC) voltage (1–30 V). In this membrane, PSSA is the polyelectrolyte, PVP is the hydrophilic basic polymer, and PVDF is the hydrophobic polymer.
