▎ 摘　　要

NOVELTY - Dopamine functionalized carbon powder and rubber composition comprises carbon black, fullerene, carbon nanotube, graphene oxide and graphene. USE - Dopamine functionalized carbon powder and rubber composition used for tire inner liner. ADVANTAGE - The dopamine functionalized carbon powder and rubber composition improves adhesion to the carcass layer and increases air permeability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a dopamine functionalized carbon powder and rubber composition, which involves adding dopamine and carbon powder to the dopamine-modified carbon powder solvent and reacting at a temperature of 50-140 degrees C for 1-72 hours.
