Recent progresses in super-hydrophobicity and micro-texturing for engineering applications

Abstract

Abstract Increasing interests have been prevalent lately among the research fraternity for the development of superhydrophobic surfaces (SHS) considering the favorable properties exuded by them. Recently, SHS have been employed effectively in diverse engineering applications like self-cleaning/anti-dust, anti-reflecting coatings, corrosion resistance, anti-biofouling, biomedical, oil-water separation, drag reduction, anti-icing, and cavitation erosion. Further, patterned topology by micro/nano surface texturing has been perceived lately as an engineering opportunity to enhance the surface performance and has opened various avenues for exploration. This work reports the recent research findings pertaining to the concept of superhydrophobicity and micro-texturing particularly in the context of their application for the impediment of the adversaries in metallic components. The comprehensive review on SHS and micro-texturing suggests that the integrated application of these surface modification techniques are proficient for mechanical interlocking of the deposited coatings.
