Fabrication method of high thermal conductive graphene oxide layer by vacuum filtration assisted transfer printing of graphene oxide colloidal solution and film fabricated by using the method thereof

摘要

Disclosed are a method for manufacturing a heat dissipation film through vacuum printing and transfer printing of a graphene oxide colloidal dispersion, and a heat dissipation film manufactured using the same. A method for manufacturing a heat dissipation film using graphene oxide according to an embodiment of the present invention includes forming plate-shaped graphene oxide particles in a plate shape; and vacuum filtering the plate-shaped graphene oxide particles and stacking them in the transverse direction to prepare a heat dissipation film, wherein the forming includes high energy ball milling of the bulk graphite particles to form the plate-like shape By exfoliating with the plate-shaped graphene oxide particles, the plate-shaped graphene oxide particles can be formed.
