This study presents a rapid, simple, and environmentally friendly method for producing superhydrophobic and self-cleaning surfaces on AISI 347 stainless steel. The resulting surfaces exhibited high contact angles and low sliding angles. The method offers potential for large-scale applications and anti-fouling purposes, with favorable mechanical properties.
The development of superhydrophobic (SHP) and self-cleaning surfaces has gained significant attention due to their potential applications in various fields. This study presents a rapid, simple, and environmentally friendly method for producing superhydrophobic and self-cleaning surfaces on AISI 347 stainless steel. The process in -volves mild chemical etching followed followed by Plasma Enhanced Chemical Vapor Deposition (PECVD) deposition of a fluorocarbon film using 1,1,1,2-tetrafluorethane (C2H2F4) as a precursor. The resulting surfaces exhibited contact angles (CA) of up to 164 degrees and sliding angles (SA) as low as 3 degrees. Characterization of the surfaces revealed favorable mechanical properties, including a maximum hardness of 1.1 GPa and an elastic modulus of 9.7 GPa. The method offers potential for large-scale applications and anti-fouling purposes, as demonstrated by initial fouling tests. The findings contribute to the development of cost-effective and durable superhydrophobic surfaces with enhanced mechanical strength and corrosion resistance.
