摘要

This study presents a straightforward electrodeposition strategy for fabricating a polytetrafluoroethylene (PTFE) coating with excellent stability on stainless steel substrates, aimed at inhibiting the deposition of MgO/CaCO2 mixed fouling. By tuning the electrodeposition parameters, two hydrophobic coatings were achieved with surface roughness values of 0.148 μm (No.1 coating) and 0.056 μm (No.2 coating). The static and dynamic antifouling performance of these coatings was systematically evaluated at different temperatures (50 °C and 90 °C). The results indicate that both the surface morphology of the coatings and the temperature jointly affect the fouling suppression efficacy. No.1 coating preferentially adsorbed fouling particles due to its microprotrusion structure. Conversely, under dynamic flow conditions at 90 °C, No.2 coating exhibited a smooth surface and a significant bubble retention effect, resulting in a higher fouling inhibition rate of 82.83%. Overall, this research provides a strong foundation for future studies and practical applications of PTFE coatings in antifouling technologies.
