Fatigue Temperature Rise of Nano‐Carbon Filler Reinforced Rubber Composites: A Comprehensive Review

ABSTRACT It is of technological and scientific importance to limit fatigue temperature rise of rubber composites reinforced with nano‐carbon filler so as to decrease negative impacts on performance. The fatigue temperature rise is the result of thermal conductivity and heat generation in rubber composites. However, the insufficient understanding of thermal conductivity and heat generation in rubber composites imposes restrictions on the design and preparation of materials with lower fatigue temperature rise. This review aims to explore the fatigue temperature rise mechanisms by analyzing the influences of various nano‐carbon fillers in rubber composites on dynamic heat generation and thermal conduction mechanisms. Factors defined by rubber matrix (e.g., chain structures and crosslinking density) and nano‐carbon filler (e.g., intrinsic thermal conductivity, filler loading, size, shape and aspect ratio, hybrid type, functionalization, etc.) are proved to exert an influence on the fatigue temperature rise of nano‐carbon filler reinforced rubber composites. Importantly, the interface between the rubber matrix and nano‐carbon filler is the main parameter used to determine the fatigue temperature rise of rubber composites. Finally, molecular dynamics simulation methods for predicting fatigue temperature rise of rubber composites are discussed as well. This review can provide some guidance for future studies in low fatigue temperature rise of rubber composites reinforced with nano‐carbon filler for developing a new generation of energy‐saving and durable rubber composites.
