An electrical responsive graphene-PVDF material and the manufacturing method thereof is disclosed in the present invention. The method includes three steps. Firstly, prepare a mother solution of PVDF. Then, add graphene powders into the mother solution of PVDF to prepare a graphene-PVDF slurry. At last, remove the solvent from the graphene-PVDF slurry to directly form an electrical responsive graphene-PVDF material. Due to the ability of transforming the non-electrical energy into the electrical energy, the electrical responsive graphene-PVDF material can be formed for many different applications in the form of individual film or of film with a substrate via various film formation methods.

Co-cured blends of fluoroelastomers of tetrafluoroethylene-propylene copolymer with cure site monomer and terpolymers of Vinylidene fluoride (VDF), Hexafluoropropylene (HFP) and Tetrafluoroethylene (TFE) with peroxide as initiator and coagent TAIC as crosslinker show improved curing performance, improved mechanical properties and improved compression set as well. The co-cured fluoroelastomers show improved chemical resistance to the solvent aging systems and better retention of mechanical properties after aging at high temperature in the solvents system.
