But, most of the reported reviews provided the limited information on fundamentals and fabrication techniques of the superhydrophobic coatings and found more directed towards the applications of superhydrophobic coatings in different sectors. A new review presents a detailed description of the fundamentals of superhydrophobic coatings, problems in manufacturing such coatings and the fabrication techniques. Additionally, the review provides a glimpse of potential applications of such coatings.

The major constraints to the development of superhydrophobic coatings are identified as the expensive superhydrophobic materials, nano feature durability, coating stability, precipitation/condensation problem amogst others. The best fabrication techniques of superhydrophobic coatings are identified as the sol-gel, wet-chemical, electrochemical deposition and Mussel-inspired chemistry.

The review has been published in Progress in Organic Coatings Volume 142, May 2020.
