The coatings have decided incorporating 1H,1H,2H,2H-perfluorooctyltriethoxysilane (FAS-17)-coated hydrophobic zinc oxide and copper nanoparticles to create hierarchical micro/nanostructures on commercial polyurethane (PU) sponges followed closely by polydimethylsiloxane (PDMS) treatment that is used to boost the binding level amongst the nanoparticles plus the sponge surface. The micro/nanotextured examples can repel various liquids including liquid, milk, coffee, liquid,
