Effective cooling systems for use in electromechanical equipment require high thermal conductivity and low density materials to remove high thermal fluxes on compressed surfaces and maintain low temperatures. Due to the large pores and irregular pore structure, the mechanical strength is low. One way to improve the mechanical strength of GFms is to add a filler with high mechanical strength. Graphite in particular has the beneficial properties of high lubrication capacity, high heat resistance, corrosion resistance and excellent thermal / electrical conductivity. In this study, GFMS was prepared using a hydrogel template method with severe wound pitch (MP), polyacrylic acid (PVA-AAC) solution and graphite powder added. The obtained GFms were labeled with GFm, GFm-0.1G, GFm-0.3G, GFm-0.5G, GFm-0.7G, and GFm-1.0G. The layer thickness of GFm-0.3G was 0.3380 nm and the crystal thickness was 32.3661 nm. The layer thickness of sample GFm-0.3G was slightly larger than GFm. |
