In order to obtain a superhydrophobic coating on an aluminum substrate, a multistage treatment was implemented. Specimens of aluminum were treated by abrasive blasting, anodization in sulfuric acid, impregnation by PDMS, rinsing in toluene to remove excess of PDMS, and curing. A rough surface with an additional low free energy layer on it resulted in a superhydrophobic effect. The coating obtained has an average contact angle of 159°. The specimens were tested in terms of durability in natural conditions. Additionally, anti-icing and anti-fouling properties were evaluated. The coating was compared with anodized aluminum obtained by a basic process.Materials (Basel, Switzerland)1042https://www.ebi.ac.uk/biostudies/studies/S-EPMC8840686biostudies-literatureSuperhydrophobic Coating Based on Porous Aluminum Oxide Modified by Polydimethylsiloxane (PDMS).PMC8840686Nasilowska BOlkowicz KBuczko ZKowalczyk KCzwartos JfalseSuperhydrophobic Coating Based on Porous Aluminum Oxide Modified by Polydimethylsiloxane (PDMS).The aim of this study was to obtain a superhydrophobic coating by modifying anodized aluminum using polydimethylsiloxane (PDMS).
