Advanced research in the field of material science and biomedicine leads to the development of materials that are efficient and cost‐effective. Graphene has been a widely studied material in recent years and graphene‐based materials exhibit exceptional properties that can be used for applications ranging from biomedical to electronics. In biomedical field, graphene‐based materials are employed in drug delivery, sensing, bioimaging and tissue engineering. However, the production of graphene from graphite and chemical precursors has certain drawbacks such as toxicity, expensive, complex fabrication process, etc. To overcome these, biomass have become a new source for graphene materials. Different types of biomass sources and various preparation methods for graphene‐based materials were reviewed. Here, the applications of biomass derived graphene‐based materials in biomedical field were discussed.

“…Nevertheless, some traditional thermal management materials, such as Cu/Mo and Cu/W, could no longer fulfill the requirements for high-power electronic devices [ 4 , 5 ]. Thus, metal matrix composites (MMCs) reinforced with high TC carbon materials, such as carbon fibers [ 6 ], graphite, diamond [ 7 ], carbon nanotubes [ 8 ] and graphene [ 9 ], have gradually come into view.…”

Graphite/Al composites had attracted significant attention for thermal management applications due to their excellent thermal properties. However, the improvement of thermal properties was restricted by the insufficient wettability between graphite and Al. In this study, silicon carbide and titanium carbide coatings have been uniformly coated on the graphite by the reactive sputtering method, and Graphite/Al laminate composites were fabricated by a hot isostatic pressing process to investigate the influence on thermal conductivity and mechanical properties. The results show that carbide coating can effectively improve the interfacial thermal conductance of SiC@Graphite/Al and TiC@Graphite/Al composites by 9.8 times and 3.4 times, respectively. After surface modification, the in-plane thermal conductivity (TC) of the composites with different volume fractions are all exceeding the 90% of the predictions. In comparison, SiC is more conducive to improving the thermal conductivity of composite materials, since the thermal conductivity of the 28.7 vol.% SiC@Graphite/Al reached the highest value of 499 W/m·K, while TiC is favorable for improving the mechanical properties. The finding is beneficial to the understanding of carbide coating engineering in the Graphite/Al composites.

“…To date, thermal management materials have been developed for several periods, but some traditional thermal management materials, such as Invar, Kovar, SiC/Al, and Si/Al, can no longer fulfill the requirements for high power electronic devices due to insufficient TC [ 3 , 4 ]. In recent years, metal matrix composites (MMCs) reinforced by carbon materials, including carbon fibers [ 5 , 6 ], graphite, diamond [ 7 , 8 ], carbon nanotubes (CNTs) [ 9 , 10 ], and graphene [ 11 ], have become promising materials for thermal management applications due to their high TC and low density.…”

“…Recently, artificial graphite films fabricated from polyimide films have attracted much attention in thermal management applications due to their high graphitization degree and high TC [ 2 , 9 ]. The in-plane TC of graphite film can reach 1100–1600 W/m·k, which is much higher than that of graphite flake.…”

Study on Fabrication and Properties of Graphite/Al Composites by Hot Isostatic Pressing-Rolling Process

et al. 2021

Graphite/Al composites have attracted much attrition due to their excellent thermal properties. However, the improvement of thermal conductivity (TC) is limited by the difficulty in controlling the orientation of graphite and the poor wettability between graphite and aluminum. In this study, a novel process for fabricating the Graphite/Al composites is proposed, which involves fabricating graphite film and aluminum foil into laminate material. Then, taking a rolling method, the fractured and well oriented graphite film can help the composite achieve high TC while maintaining a certain strength. The result reveals that both single and total reduction have a significant influence on the diameter and orientation of the graphite, and by adjusting the process parameters, composites with high TC can be acquired at a relatively low reinforcement volume. This near-net-forming process can directly meet the thickness requirements for electronic packaging and avoids the exposure of graphite to the surface during secondary processing, which is promising to promote the application for high TC Graphite/Al composites in thermal management.
