Superhydrophobic Surfaces by Electrochemical Processes

Abstract

This review is an exhaustive representation of the electrochemical processes reported in the literature to produce superhydrophobic surfaces. Due to the intensive demand in the elaboration of superhydrophobic materials using low-cost, reproducible and fast methods, the use of strategies based on electrochemical processes have exponentially grown these last five years. These strategies are separated in two parts: the oxidation processes, such as oxidation of metals in solution, the anodization of metals or the electrodeposition of conducting polymers, and the reduction processed such as the electrodeposition of metals or the galvanic deposition. One of the main advantages of the electrochemical processes is the relative easiness to produce various surface morphologies and a precise control of the structures at a micro- or a nanoscale.

Superhydrophobic surfaces for corrosion protection: a review of recent progresses and future directions

“…In recent years, improving the corrosion resistance of metallic materials by surface superhydrophobization has become one of the hottest research areas in corrosion and protection. Compared to existing literature which has frequently reviewed the theories, preparation, and applications of superhydrophobic surfaces, [8][9][10][11][12][13][14][15] this review mainly focuses on the most recent developments of superhydrophobic surfaces for anticorrosion purposes. The authors review the typical preparation techniques of superhydrophobic anticorrosive surfaces and their anticorrosive performance, and provide a critical discussion of some mechanistic aspects of corrosion protection based on superhydrophobicity.…”

Bioinspired approach toward molecular electrets: synthetic proteome for materials

“…The process of designing and developing such walkers, however, plays a key role in advancing biomechanics and demonstrating its potential utility for rehabilitation medicine [66][67][68][69][70], and outside of biology [71][72][73][74][75][76][77]. Examples of taking structural features from nature and attaining the targeted functionalities include: (1) the invention of Velcro, for which George de Mestral used concepts from the burrs of the burdock plant [78,79], and (2) superhydrophobic surfaces, which copy nanostructures of plant leaves capable of repelling water droplets [80][81][82][83][84][85].…”

Superhydrophobic polyimide films with high thermal endurance via UV photo-oxidation

“…1H,1H,2H,2H-Perfluorodecyltriethoxysilane (FAS, C 10 F 17 H 4 Si(OCH 2 CH 3 ) 3 ) was supplied by Alfa Aesar (Ward Hill, MA, USA). Ultra-pure water was prepared using a Milli-Q-Plus system (Millipore, Bedford, MA, USA).…”
