Abstract
The invention utilizes swelling and fusion effects of graphene oxide in a solvent to implement cross-linked bonding of a graphene material itself and materials such as polymers, metal, paper, glass, carbon materials, and ceramics. The present invention not only overcomes the shortcoming in traditional adhesives of residual formaldehyde, but also has short drying time, high bonding strength and high corrosion resistance. The present invention is widely applied in the fields of aviation, aerospace, automobiles, machinery, construction, chemical, light industry, electronics, electrical appliances, and daily life, etc.
