Abstract:

In order to achieve superhydrophobic characteristics, Zn–CaO nanoparticles has been electropositively coated on mild steel substrates and then functionalized using silicone rubber. SEM morphological characteristics reveal that the electrodeposited zinc films and functionalized silicone reveal a porous, rectangular structure. Infrared spectroscopy and X-ray diffraction (XRD) were used to determine the functional group and phases Zn–CaO nanoparticles functionalized with silicone has been discovered and offers superhydrophobic qualities with a 175° contact angle. Superhydrophobic zinc-coated steel has been shown to be more corrosion resistant than mild steel in simulated saltwater. Similarly, the centrifugal adhesion test results show that the observed superhydrophobic surfaces' ice adhesion strength was 6.5 times lower than that of mild steel. This coating has potential uses in marine environments to lessen ice adhesion and prevent corrosion.
