ABSTRACT
Carbon nanotubes (CNTs), renowned for their exceptional mechanical, electrical, and thermal properties, are regarded as the most promising multifunctional reinforcement filler for rubber composites. However, existing reviews on CNT-reinforced composites predominantly focus on cementitious and metallic matrices, with few studies systematically addressing the unique challenges of “dispersion-homogenization-interface coupling” posed by the extreme viscosity, significant deformation, and complex cross-linked networks inherent to rubber matrices. This review employs a systematic evaluation approach to comprehensively summarize recent advancements in CNT-reinforced rubber-based composites. Focusing on rubber matrices, this paper compares non-thermal dispersion with thermal-assisted dispersion techniques optimized for processing high-viscosity elastomers, elucidates the unique multi-scale synergistic reinforcement mechanism inherent to viscoelastic networks, and clarifies the intrinsic correlations between processing parameters and final performance attributes such as wear resistance, tear strength, and electromagnetic shielding capabilities.
