“…Typically, thermally conductive polymer-based composites are fabricated by dispersing high-thermal-conductive fillers, including carbon-based fillers, metals, and inorganic particles, into the polymer matrix. Carbon-based fillers include graphite, carbon fibers, graphene, and carbon nanotubes (CNTs), each of which shows high TC and excellent mechanical performance. − Particularly, graphite has excellent thermal and electrical conductivities, a high self-lubrication ability, resistance to both high and low temperatures, good corrosion resistance, and good chemical stability. Additionally, expanded graphite (EG) can be synthesized easily and affordably by reacting natural flake graphite with an interlaminar agent and then expanding the graphite sheets at a high temperature; this increases the specific surface area of the graphite sheets while retaining the above-mentioned advantageous properties of graphite.…”

Epoxy resin is extensively applied in the electronics and electrical fields because of its outstanding comprehensive performance. However, the low thermal conductivity (TC) limits its application in thermal interface materials. In the present work, epoxy-based hybrid composites with high TC were prepared by using expanded graphite (EG) and copper (Cu) nanoparticles as thermally conductive hybrid fillers via hot blending and compression-curing processes. Additionally, the influence of the Cu content on the thermal properties, mechanical properties, and morphology of each epoxy/EG/Cu composite was investigated. According to the results, the epoxy/EG/Cu composite showed a maximum TC of 9.74 W/(m·K) at a fixed EG content of 60 wt % owing to the addition of 10 wt % Cu. After the addition of 10 wt % Cu, the flexural strength, flexural modulus, and impact strengths of epoxy/EG/Cu composites were improved from 27.9 MPa, 9.72 GPa, and 0.81 kJ/m2 to 37.5 MPa, 10.88 GPa, and 0.91 kJ/m2, respectively. Hence, this study offers a feasible strategy for the design of epoxy hybrid composites with excellent TC that can be applied to thermal interface materials.
