Superamphiphobic Coating: Combination of superhydrophobicity and superoleophobicity

摘要

Superhydrophobic coatings are those with water contact angle more than 1500 and superoleophobic coatings are oil repellent with resistance to most of the organic liquid. Superamphiphobic coatings are the new advance approach of the coating which combines the advantages of above two coatings and act as oil and water repellent at the same time. Due to this combined advantage it can act as self cleaning coating, Antifingerprint coating, Anticorrosive coating. Anti-smudge coating at the same time and helps to improve the durability and service life of the substrate on which this coating is applied. The creation of this coating is based on the principle of chemical composition and surface topography. The surface can be make superamphiphobic by various methods like sol-gel coating, electrospinning in case of fiber, plasma etching in case of plastic substrate etc.
