NOVELTY - Teflon (RTM: Polytetrafluoroethylene) coated magnesium/magnesium foam containing graphene-carbon nanotube (CNT), prepared by crushing polytetrafluoroethylene (PTFE) into powder, mixing PTFE powder and liquid phase according to PTFE powder to ethanol, PTFE powder to methanol, PTFE powder to isopropyl alcohol, PTFE powder to toluene or PTFE powder to water ratio of 10:90, 10:90, 20:80, 40:60 and 50:50 respectively, coating the obtained solution on surface of magnesium/magnesium foam containing graphene-CNT, drying at 120 degrees C, heat-treating at 220 degrees C and curing at 360-400 degrees C, is claimed. USE - The Teflon (RTM: Polytetrafluoroethylene) coated magnesium/magnesium foam containing graphene-CNT is useful in hydrogen storage. ADVANTAGE - The Teflon (RTM: Polytetrafluoroethylene) coating prevents moisture and oxide film formation on magnesium/magnesium foam containing graphene-CNT surface and improves hydrogen storage capacity. DETAILED DESCRIPTION - Teflon (RTM: Polytetrafluoroethylene) coated magnesium/magnesium foam containing graphene-carbon nanotube (CNT), prepared by crushing polytetrafluoroethylene (PTFE) into powder, mixing PTFE powder and liquid phase according to PTFE powder to ethanol, PTFE powder to methanol, PTFE powder to isopropyl alcohol, PTFE powder to toluene or PTFE powder to water ratio of 10:90, 10:90, 20:80, 40:60 and 50:50 respectively, coating the obtained solution on surface of magnesium/magnesium foam containing graphene-CNT, drying at 120 degrees C, heat-treating at 220 degrees C until the thickness of coating is 0.1 mm-0.2 mm and curing at 360-400 degrees C for 1-2 minutes, is claimed.
