Abstract:
Superhydrophobic/superoleophobic phenomenon in nature have attracted extensive attention from researchers in surface interface science, micro-nano manufacturing, nano coating and other fields, and have shown great application prospects in people's production and life. Based on the basic wettability theory, this paper introduces the main types of micro-nano rough structures on superoleophobic surfaces and the principle of reducing surface energy. The relationship between the micro-nano rough structure, chemical modification, and wettability also be explored, and the main methods for preparing superamphiphobic surfaces are summarized. Finally, the main applications status of the superamphiphobic surface are summarized, and the shortcomings and defects of the superamphiphobic surface are analyzed. Likewise, the future development direction of the superamphiphobic surface is prospected.
