Abstract

See full text

The invention provide a manufacturing method for producing conductive adhesive with spherical graphene, and the steps comprise as following: step 1: preparing monomer, initiator, a dispersing agent and solvent to manufacture a monomer compound, and use the monomer compound to produce polymer micro ball; step 2: heating pre-treatment or plasma etching pre-treatment to the said polymer micro ball; step 3: by chemical vapor deposition, the polymer micro ball after pre-treatment from step 2 to grow graphene outside surfaces or inside polymer micro ball, and then obtain the spherical graphene; step 4: producing epoxy gel system made by epoxy, hardener and accelerant with a certain ratio mixing homogeneously; step 5: dispersing the spherical graphene from step 3 into the epoxy gel system to produce pre-material of conductive adhesive of spherical graphene; Step 6: deforming the pre-material of conductive adhesive of spherical graphene, and then obtain conductive adhesive of spherical graphene.
