“…Since 2004, bulk high entropy alloy (HEA) materials have attracted much more attention as a novel class of advanced structural materials, and the research for the related preparation methods and phase structures has matured considerably [1]. The common high-entropy effects on thermodynamics [2], sluggish diffusion on kinetics [3], severe lattice distortion on structures [4], and cocktail effects on properties [5], promise these HEA materials excellent mechanical performance, good friction and wear performance, high-temperature resistance, irradiation resistance, and corrosion resistance [6][7][8][9][10], etc. However, quite many metal shell materials applied in high-end electronic products show poor self-cleaning properties due to the hydrophilicity and lipophilicity of metals themselves, which limits wide application.…”
