High surface area morphologies are frequently embraced in the design of highly active materials. This approach is essential in the fabrication of highly water repellent (superhydrophobic) materials. Such that, a high surface roughness magnifies the water repelling properties of hydrophobic materials, while also trapping air at the surface – increasing hydrophobicity further.1 Polymers are ideal for manufacturing these materials, as hydrophobic polymers can be easily engineered to provide high surface roughnesses.2 Superhydrophobic surfaces have such a low affinity for water, that water forms spherical droplets upon contact. These droplets roll around due to low attractive forces, with many of the potential applications stemming from this rolling motion. The applications of superhydrophobic technology range from; self-cleaning and anti-biofouling, to fluid drag reduction, and oil-water separation. Relevant industries are therefore extensive, but include; healthcare, surface protection (industrial coatings), and water treatment facilities. The presentation will provide a view of cutting edge research into superhydrophobic polymers, as well as an outlook for the future of these materials. This includes overcoming the major challenge of forming robust materials, for use in ‘real-world’ conditions. Facilitated by coatings that utilise reinforcing additives that impart strength to films, and a secure attachment to an underlying substrate. The extension of these polymers as support matrices for high surface area functional materials will also be explored. Detailing the inclusion of nanoparticles to impart additional properties, in addition to their testing and analysis.
