제목 | Highly improved thermal and mechanical properties of graphite foams containing graphite filler |
초록 | Graphite powder with highly graphite structure is used as a filler material in the preparation of graphite foams (GFms) for enhancing thermal/mechanical property. The GFms are prepared using hydrogel template method with mesophase pitch, polyvinyl alcohol-acrylic acid (PVA-AAc) solution and graphite powder. The 0.3 w/w% graphite added GFm has the increased crystalline thickness (Lc) up to 11.18% compared to the sample without graphite powder. These increased crystalline thicknesses of GFms has affected to be increased thermal conductivity up to 59.30%. The compressive strength has been also increased up to 120.52% compared to the sample without graphite powder as increasing apparent density up to 4.05%.
