Epoxy, one of the most important thermosetting polymers, is used in a wide range of applications as adhesives, coatings, and materials for composite structures due to its outstanding performance, low processing capacity and low cost. Due to the superior properties of carbon nanomaterials in thermal conductivity, flame retardation, mechanical stability, electrical conductivity and environmental compatibility, these nanomaterials have attracted global attention. In the present article, a review of past literature on improving the performance of epoxy resin by adding carbon nanomaterials is presented. The correlation of structural performance for epoxy modified with various carbon nanomaterials has been closely analyzed. Improvement of mechanical, electrical, thermal conductivity and flame deterioration for epoxy resin has been investigated. Challenges and opportunities in the composite of functionalized nano-materials epoxy are also discussed. The purpose of this research is to provide a comprehensive understanding of the multi-purpose epoxy resins including carbon nanomaterials to date and assess its future prospects. Also, the relationship and comparison of the structure and performance of various carbon nanomaterials has been evaluated. The improvement of mechanical, electrical, thermal conductivity and carbon dioxide epoxy flame retardant properties has been thoroughly investigated. Finally, the conclusions and prospects for the future and the hope of facilitating progress are presented at the end of the paper.
