Abstract: A superhydrophobic coating composition is provided comprising an NP component and a radical initiator (RI), wherein the NP component comprises NP particles having organic moieties bound to the surface of the NP particles. Also provided is a superhydrophobic coating composition further comprising a fluid. Also provided is a method for preparing a super-hydrophobic (SH) surface, where the method includes mixing an NP component with at least one RI and possibly with a fluid, thereby providing a coating composition, applying the coating composition onto a substrate (pre-coated or containing oxides) thereby providing a coated substrate; and applying radiation to the coated substrate, thereby providing the SH surface on which at least part of the NP component is covalently bound, directly or indirectly, to the substrate.
