Abstract

The invention discloses an epoxy resin and functional graphene integrated filtering IC. The epoxy resin and functional graphene integrated filtering IC comprises a filtering coil and a filtering medium, and the filtering medium comprises, by weight, 5-20% of a functional graphene material, 1-5% of an amine curing agent, and the balance of epoxy resin. The epoxy resin and functional graphene integrated filtering IC is obtained through mixing a main raw material epoxy resin with the functional graphene material, adding the curing agent and carrying out curing molding. The epoxy resin and functional graphene integrated filtering IC has excellent functions, reaches a surprising range of -6-60 db, and is suitable for being applied to filtering of most harmonic waves. The making method has the advantages of simplicity and low making cost; and the epoxy resin and functional graphene integrated filtering IC has the advantages of high economic values, high cost performance, and making up for the deficiency in mid-low end filtering products.

Description

technical field [0001] The invention relates to the technical field of filter circuits, in particular to an epoxy resin functional graphene integrated filter IC and a preparation method thereof. Background technique [0002] The filter IC (Silicone Graphene Liquid Metal) has powerful functions, and the filter medium material used in its development is mainly aimed at the high-end and high-precision filter market. Existing filter ICs have complex manufacturing process and high production cost. They are used in middle and low-end filter products, and there are defects such as resource waste, high cost, and low economic value. Therefore, there is an urgent need for middle and low-end filters in the market. IC. [0003] Epoxy resins are widely used in daily human life, and bisphenol A epoxy resin is the most commonly used epoxy resin. By reacting with a curing agent, the epoxy resin can form a three-dimensional cross-linked polymer network, and then the network structure is cu...
