NOVELTY - Omega graphene liquid metal filter plane choke comprises a choke base layer, a filter medium layer and a packaging material layer, where the material of the choke base layer is copper wire, and filter media layer includes 1-10 wt.% functional graphene materials, 1-30 wt.% liquid metal, 2-6 wt.% amine curing agent, and rest is epoxy resin. USE - Omega graphene liquid metal filter plane choke. ADVANTAGE - The omega graphene liquid metal filter plane choke has good filtering performance, low energy loss, and filter effect reaches -1-5db. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing an omega graphene liquid metal filter plane choke, which involves: (A) taking a copper wire, keeping one end straight for a distance, then bending the other end of the copper wire on the plane to a first arc of radius r, and then bending the end of the first arc away from the straight line into radius R second arc, the first arc and the second arc are set tangentially, the center point of the second arc is the origin, and the line segment formed by the tangent point and the origin of the first arc and the second arc angle between the origin and the line segment formed by the vertical end of the choke line end and third circle and the fourth arc are wound around the line segment formed by the origin and the line end of the choke line end as the symmetry axis the fourth arc is wound, the end of the fourth arc far away from the third arc is wound into a straight line parallel to the straight end of the choke coil to complete the winding of the first Omega type, where the winding method of multiple Omega-type windings is the same operation, and multiple Omega-type windings are performed to obtain a flat choke base layer, and the vertical distance between two adjacent Omega-types is two adjacent omega types are on the same side or different sides of the choke straight line direction; (B) weighing the raw material of the filter medium layer comprises 1-10 wt.% functional graphene material, 1-30 wt.% liquid metal, 2-6 wt.% amine curing agent, and the balance is epoxy resin; (C) adding functional graphene material and liquid metal to the epoxy resin at a rate of 3 g / min, stirring mixture at a speed of 400 r / min while being added; (D) mixing mixture, adding to the ultrasonic oscillator, and ultrasonically dispersing for 16 minutes to obtain a mixed solution A; (E) adding amine curing agent weighed to the mixed solution A obtained, keeping the rotation speed unchanged, and stirring and mixing for 32 minutes to obtain a filter medium B; and (F) applying filter medium B on both sides of the planar choke, sealing two sides, heating and filtering to obtain omega graphene liquid metal filtering planar choke.
