High adhesive force, superhydrophobic surfaces

The combination of changes in surface chemistry and surface roughness can enhance stimuli-responsive wettability. Here, we have presented a simple one-step method to prepare apolybenzoxazine-silica nanoparticle film, displaying reversible wettability via a solvent treatment. The difference in the water CAs of the same composite film, before and after solvent treatment was achieved to be 19° with silica content of 120 phr. Compared with a traditional superhydrophobic surface, the as-prepared film can be modified to show not only hydrophobicity but also a high adhesion force with water. Our results are considered to be significant in terms of their importance to academic research and industrial applications.
