▎ 摘　　要

Silica-graphene hybrid (HGKS) with good dispersion and strong interfacial interactions was fabricated by hydrogenbonding assembly. HGKS was incorporated into natural rubber (NR) to develop high-performance tire treads. During vulcanized process of HGKS filled NR (NR/HGKS), HGKS can participate in the process to form dual dynamic network structure. The interfacial interaction between HGKS and NR due to the dispersion of HGKS was investigated. The strong covalent interaction between NR and HGKS is the most important factor to determine the ultimate performance of rubber composites. In this contribution, a series of HGKS with different hybrid grafting ratio are prepared to reveal the effects of changes in filler surface properties on the structure and mechanical properties of rubber composites. It has been demonstrated that it is an effective hybrid technique to drastically improve its dispersibility in NR and form strong interfacial reactions, and HGKS is expected to be used as a new type of reinforcing filler for the manufacture of high-performance green tire materials.
