Summary:Graphite and carbon are attractive carbon-carbon (C/C) composite materials for applications due to exceptional electrical transport properties and high charge mobility. The liquid nitrogen cold quenching method could increase porous, hardness, and electrical conductivity. Composite material graphite electrode waste/natural carbon black / polyvinylidene fluoride (GEW/NCB/PVDF) was made by mixing 70wt% GEW, 10wt% NCB and 20 wt% PVDF with non-solvent method by means ball mill for 900 minutes. The mixture was then moulded using hot press machine at pressure of 5.5 MPa, temperature of 150°C for 60 minutes with dimension of 5 × 5 × 0.3 cm3. After that, put it off into liquid nitrogen quickly. The conclusion is preparation of GEW/NCB/PVDF composite by using liquid nitrogen cold quenching could increase porous, hardness, and electrical conductivity. However, this composite shows decrease in density.
