This work reports the preparation of core-shell nanoparticles of tapered interface structures. The hard core is made from crosslinked polystyrene, and the soft hairy shell is made of tapered poly(isoprene-co-styrene). We used them as reinforcing fillers in synthetic rubbers. Our experimental results show that the nanoparticles possessing this unique tapered structures can provide superior reinforcement, with excellent tensile strength and wear durability, that conventional fillers such as carbon black or silica cannot match.
