Preparation And Properties Of Graphene Electric And Magnetic Functional Film

In this paper,graphene electrical and magnetic functional films were prepared,and different functional devices were fabricated.Subsequently,the different motion modes and influencing factors of the functional film under electrical actuation were explored.Finally,we prepared the magnetic graphene composite membrane to complete the transformation of mechanical energy and light energy into electric energy.The reduction of graphene oxide / silicone rubber bilayer film was first prepared,which can be stimulated under DC / AC voltage load respectively.The bilayer film can achieve fast response and large bending angle under DC voltage,and continuous oscillation with AC voltage loading.The mechanism of the actuation,influencing factors and stability were tested in this research and this flexibility bilayer film has good actuating and stability.Different functional devices based on the electro-thermal mechanism were designed,and a preliminary exploration was made on the practical application and bionics of graphene electroactive film.A composite of magnetically reduced graphene oxide and latex was prepared to obtain a magnetic graphene composite film.The device is designed by the electromagnetic induction to convert mechanical energy and light energy into electrical energy respectively,thereby realizing the conversion of two different forms of energy into electrical energy.The induced electromotive force and induced current were tested and a simple comparison of the two forms of energy conversion was performed.The magnetic graphene composite film has certain practicality,and can be studied as an energy conversion material used in the production of functional devices.
