NOVELTY - Taichi-type graphene liquid metal filter plane choke coil comprises choke base layer, the filter dielectric layer and the packaging material layer, the material of the choke base layer is copper wire, the filter medium layer comprises 1-10 wt.% functional graphene materials, 1-30 wt.% liquid metal, 2-6 wt.% amine curing agent, and epoxy resin (balance). USE - The filter plane choke coil is useful in filter materials (claimed). ADVANTAGE - The filter plane choke: has a polarity current, good filtering performance, low energy loss, and a filtering effect of 3-6 db. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing taichi-type graphene liquid metal filter plane choke coil comprising (1) taking a copper wire wound according to the winding shape of the straight section a distance C, winding the first curve, where the horizontal height of the first curve is H, and the horizontal width of the curve is D, winding the second section of the curve, rotating the second section of the curve and the first section of the curve by an odd multiple of 180 degree, and obtaining the first Taichi-type choke, where the winding method of the chokes is the same or the opposite operation, performing the horizontal winding of multiple tai-chi chokes, winding a straight line segment of length C between two adjacent Taichi chokes to obtain a plane grass-roots choke, (2). weighing the raw material of the filter medium layer, (3) adding the functional graphene material and liquid metal to the epoxy resin at the rate of 3 g/minute, stirring the mixture at a speed of 400 rotations/minute, adding to the material, mixing the mixture, adding to the ultrasonic oscillator, and ultrasonically dispersing for 16 minutes to obtain a mixed solution A evenly dispersed, (4) adding the amine curing agent to the mixed solution A obtained, keeping the rotation speed unchanged, stirring and mixing for 32 minutes to obtain a filter medium B, and (5) applying the filter medium B on both sides of the base layer of the flat Taichi choke, sealing, completing the sealing, heating and solidifying to obtain the Taichi-type graphene liquid metal filter plane choke coil.
