Nanocomposites with antimicrobial nanoparticles offer a solution by developing an antibiofilm surface that has antibacterial material and anti microbe adherence. This research aims to synthesize Slippery Liquid-Infused Porous Surfaces (SLIPS) using zinc-oxide thin films via spray coating method, providing an environmentally friendly approach to creating anti-biofouling surfaces with applications in anti-corrosion, biomedical, and antifouling technologies. ZnO thin films were created by spraying sol containing zinc acetate dihydrate, ethanol, and monoethanolamine on the glass slides followed by calcination. SLIPS were then produced by immersing these films in silicone oil with a variety of viscosity (350 cps and 1000 cps).
