Superamphiphobic coatings with excellent properties
Graded fillers were used to improve thermal conductivity and war resistance.
Superamphiphobic coatings with high thermal conductivity and wear resistance have attracted wide attention in academic fields, but their construction through sheet fillers is very challenging. In a new study, the graded filling of modified flake graphite and modified Al2O3 was used to prepare epoxy resin/polytetrafluoroethylene powder/modified flake graphite/modified Al2O3 (EP/PTFE/FG/Al2O3) coatings using a two-step spray method, which can ensure stable non-wetting performance toward water, acid-base solutions, glycerol and ethylene glycol.
More importantly, it also promised excellent wear resistance and high thermal conductivity. Furthermore, salt spray tests indicated that the EP/PTFE/FG/Al2O3 coating had outstanding corrosion resistance. It can be foreseen that the simple but effective superamphiphobic coatings will be applied in the fields of thermal conductivity and corrosion protection.
