▎ 摘 要
NOVELTY - Graphene composite film is prepared by uniformly mixing 3-5 pts. wt. copper powder, 10-20 pts. wt. butyl acrylate, 5-10 pts. wt. guar gum, and 1-3 pts. wt. magnesium silicate to obtain complexing agent, uniformly coating substrate material to obtain thickness of 0.1 mm, uniformly coating graphite film on complexing agent, calcining at 50 degrees C for 30 minutes, and cutting. USE - Graphene composite film (claimed). ADVANTAGE - The graphene composite film has good thermal conductivity.
