▎ 摘　　要

NOVELTY - Preparation of functionalized graphene/phenolic resin involves uniformly mixing phenol and formaldehyde, adding a functionalized graphene oxide, ultrasonically treating the obtained mixture, heating to 50 degrees C, adding a certain amount of catalyst, heating the resultant product to 85-95 degrees C and reacting for 3-4 hours. USE - Preparation of functionalized graphene/phenolic resin (claimed) used for friction material. ADVANTAGE - The method enables simple and easy preparation of functionalized graphene/phenolic resin having excellent toughness and heat resistance using simple production equipment. The friction material obtained using the functionalized graphene/phenolic resin has excellent thermal property, mechanical property and friction property.
