Embodiment Construction
[0009] Several best examples of the present invention are given below: Example 1 (1) According to the mass ratio of graphene and epoxy resin being 8:92, weigh the required powder mass. (2) Mix the above powders evenly, and perform high-energy ball milling on a planetary ball mill for 10 hours. (3) Pass the ball-milled powder through a 300-mesh sieve for later use. (4) Add an appropriate amount of PVA binder to the sieved mixed powder, stir evenly and put it into a mold for hot pressing. Among them, the molding pressure is 30 MPa, and the molding temperature is 120°C. (5) The dielectric constant value of the composite material prepared by the above process is kept at about -6 in the frequency range of 100 MHz to 1 GHz.
[0010] Example 2 (1) According to the mass ratio of graphene and epoxy resin being 6:94, weigh the required powder mass. (2) Mix the above powders evenly, and perform high-energy ball milling on a planetary ball mill for 10 hours. (3) Pass the ball-milled p...
