Rational Design of High-Performance Nanomaterials for Electric Vehicle Tires

Abstract

In today's society, the market limitations of electric vehicle tires are relatively poor wear resistance and rolling resistance. These two problems restrict the further development of electric vehicles, accelerate energy consumption and environmental pollution, and bring hidden dangers to users. In this paper, the principle of tire wear resistance and the cause of excessive rolling resistance related to tire deformation are analyzed from the perspective of materials. At present, these two problems can be improved by adding nanomaterials to automobile tire materials (natural rubber and synthetic rubber). The tire's thermal conductivity and wear resistance can be improved by inserting Silica and a small amount of nano-diamond. This paper will also discuss the unique advantages of carbon black with different particle sizes as filler by analyzing the effects of modified Silica and carbon black on the molecular rubber chain. On this basis, this paper will also explain the drawbacks of nanofiller materials.
