▎ 摘 要
NOVELTY - Graphite balls are added to mill to obtain graphene nanosheet. The nylon 66 and KH550-type silane coupling agent in predetermined ratio are added to obtained graphene nanosheet in absolute ethyl alcohol medium, to obtain graphene nanosheet/nylon 66 composite material. USE - Preparation of graphene nanosheet/nylon 66 composite material. ADVANTAGE - The graphene nanosheet/nylon 66 composite material with high thermal-conduction characteristics is efficiently prepared, by simple method.
