Abstract (en)
[origin: EP4148165A1] The present disclosure disclose a method for preparing a heat dissipation component with high flexibility made of a graphite or graphene material, which includes that follow steps: 1) plasma cleaning a graphite or graphene raw material; 2) taking preparation materials of an activator including the following components in percentage by weight: 10-20% of sulfuric acid, 0.05-1% of an OP-10 surfactant, 0.05-1% of sodium dodecyl sulfate, and the balance of water; 3) continually cleaning the graphite or graphene raw material with the activator; 4) cleaning the graphite or graphene raw material with deionized water; 5) conducting a electroplating process on a surface of the graphite or graphene raw material to form a copper film layer; 6) continually cleaning the graphite or graphene raw material with deionized water; 7) forming a protective film on the graphite or graphene raw material by soaking; and 8) drying the graphite or graphene raw material electroplated with the copper film layer. Compared with the prior art, in the present disclosure, the surface of graphite or graphene treated with the activator has a uniform copper film layer with good binding quality during electroplating, and the flexibility of the prepared heat dissipation component is enhanced.
