Hydrophilic Surface Treatment of Carbon Powder Using CO2 Plasma Activated Gas

Carbon powders exhibit electrical conductivity that causes the to agglomerate due applied electrostatic forces and discharges capacitance when used for surface treatments with plasma sources. To avoid this obstacle, a non-direct method is active gas generated through plasma. This in contact carbon powder so hydrophilic characteristics are formed. It carboxyl COO− functional group improvement it shown increase after soft oxidation. The wettability of gradually improves more treatment time. simple water dispersion test. Eventually, dispersed aqueous solution separates powder, which either floats or sinks. sample treated 60 min continuously sustain dispersibility over long period
