Abstract
The present disclosure generally relates to the field of tyre technology and pertains to compositions employed for manufacturing tyre treads. More particularly, the present disclosure provides a composition comprising functionalized styrene butadiene polymer (SBR) and graphene as a reinforcing filler, and processes for preparation and applications thereof. The reinforcement of functionalized SBR with graphene filler shows homogeneous dispersion of graphene via chemical bonding with functionalized SBR, reduces particle-particle interactions of graphene filler, reduces filler-filler interaction and hence increases in filler-graphene interaction which shows the improvement in properties such as wet grip, rolling resistance, modulus, hardness and tensile properties, rheological properties etc. A tyre tread made of the present composition is superior to a tyre tread manufactured using a composition comprising traditional fillers, such as carbon black.
