Graphene tire

Graphene tire

In recent years, the global tire industry has continued to move toward lower rolling resistance, higher wear resistance, greater safety, and energy saving and carbon reduction. In addition to continuous optimization of rubber formulations, various nanomaterials have gradually been introduced into tire reinforcement systems to improve the mechanical properties, durability, and energy efficiency of materials. Graphene, as one of the strongest two-dimensional nanomaterials known in terms of mechanical strength, has a high aspect ratio, high specific surface area, high thermal conductivity, and excellent mechanical reinforcement capability, and is therefore regarded as a promising next-generation rubber reinforcement material. In recent years, multiple studies have indicated that properly dispersed graphene can improve the processing flowability, tensile strength, wear resistance, and dynamic mechanical properties of rubber composites. However, the actual effectiveness of graphene in rubber is still influenced by factors such as graphene source, number of layers, flake size, purity, dispersibility, and formulation design, and therefore its engineering application value still needs to be validated through practical formulation testing.
