NOVELTY - Angle type graphene liquid metal filtering plane choke coil is composed of a choke base layer, a filter medium layer and a packaging material layer. The material of the choke base layer is copper wire. The filter medium layer comprises 1-10 wt.% functional graphene material, 1-30 wt.% liquid metal, and 2-6 wt.% amine curing agent and balanced amount of epoxy resin. USE - Angle type graphene liquid metal filtering plane choke coil. ADVANTAGE - The angle type graphene liquid metal filtering plane choke coil has good filtering performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing angle type graphene liquid metal filtering plane choke coil, which involves: (A) taking copper wire; (B) utilizing non-starting end of the straight segment as the axis to wind the second straight segment symmetrically to form the first angular shape; (C) weighing 1-10 wt.% functional graphene material, 1-30 wt.% liquid metal, 2-6 wt.% amine curing agent, and the balance is epoxy resin; (D) adding functional graphene material and liquid metal to the epoxy resin at a rate of 3 g / min; (E) stirring the mixture; (F) dispersing the mixture to obtain a mixed solution A; (G) applying filter medium B on both sides of the planar choke; (H) sealing; and (I) heating and curing.
