constructing bioinspired functional films with various superhydrophobic
functions, including self-cleaning, anticorrosion, antibioadhesion,
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
the rationally designed, multifunctional self-assembled nanoparticles
with tunable functionalities of covalent cross-linking and hydrophobicity
for constructing three-dimensionally interconnected superhydrophobic
composite films via a facile solution-based fabrication at room temperature.
The multifunctional self-assembled nanoparticles allow the systematic
control of functionalities of composite films, as well as the stable
formation of covalently linked superhydrophobic composite films with
excellent flexibility (bending radii of 6.5 and 3.0 mm, 1000 cycles)
and self-healing ability (water contact angle > 150°, ≥10
cycles). The presented strategy can be a versatile and effective route
to generating other advanced functional films with covalently interconnected
composite networks.
