For constructing bio-inspired functional films with various superhydrophobic functions including self-cleaning, anti-corrosion, anti-bioadhesion, and oil-water separation, hydrophobic nanomaterials have been widely used as crucial structural components. In general, hydrophobic nanomaterials, however, cannot form strong chemical bond networks in organic-inorganic hybrid composite films because of the absence of chemically compatible binding components. Herein, we report bio-inspired design and synthesis of multifunctional hybrid nanomaterials with tunable functionalities of covalent cross-linking and hydrophobicity for constructing three-imensionally interconnected superhydrophobic composite films via a facile solution- based fabrication at room temperature. The multifunctional hybrid nanomaterials allow the systematic control of functionalities of composite films, as well as the stable formation of covalently linked superhydrophobic composite films with excellent flexibility (a bending radius of 6.5mm, 1000cycles) and self-healing ability (water contact angle > 150°, ≥ 10cycles). The presented strategy can be a versatile and effective route to generating other advanced functional films with covalently interconnected composite networks.
