AbstractSuperhydrophobic coatings are increasingly being evaluated as anticorrosion interventions in exceedingly hydrated environments. However, concerns about their long-term durability and amenability to large-area applications in marine environments are still hindering commercial-scale deployment. This study is focused on development of easy-to-apply superhydrophobic coatings, with multifunctional capabilities, in order to extend the integrity and durability of the coatings in harsh marine environments. Here, a set of facile methods involving selective chemical etching using concentrated NaOH, as well as fluorination with perfluoropolyether methyl ester were adopted to fabricate a superhydrophobic surface on basalt scales, having the required rough hierarchical micro-nanotextured and low surface energy. The superhydrophobic basalt scales were subsequently aligned atop a fluorocarbon resin, pre-deposited on a metal substrate, to yield a multifunctional superhydrophobic coating (3 mu L water droplet; contact angle = 165.1 degrees, rolling angle = 0.7 degrees), easily amenable to large surface area application and having excellent wear resistance, UV-aging resistance, salt spray resistance, corrosion resistance and antibacterial capabilities.
