Superhydrophobic TiO 2 /polyvinylidene fluoride composite surface with reversible wettability switching and corrosion resistance

Switchable and Reversible Superhydrophobic Surfaces: Part One

“…In order to enhance the stability of the light-sensitive materials, nanocomposites are often performed [103][104][105][106][107][108][109][110][111][112][113][114]. For example, superhydrophobic TiO 2 /polystyrene (PS) nanocomposites were prepared in the literature.…”

“…Moreover, the photocatalytic properties of TiO 2 were also useful to treat dye waste water. Fluorinated compounds or polymers can also be used in order to enhance the superhydrophobic properties [112][113][114]. For example, TiO 2 /poly(vinylidene fluoride) (PVDF) displayed both extremely high θ w = 160.1 and low sliding angle (5.5 ), and anticorrosive properties [112].…”

Electrochemical route to prepare polyaniline-coated meshes with controllable pore size for switchable emulsion separation

“…To satisfy different practical demands, smart materials as building blocks have been exploited to prepare interface materials with switchable wettability in response to various external stimuli [19][20][21][22][23][24][25][26][27][28]. For example, Wang and co-workers obtained smart surfaces comprising blocks of pH-responsive poly(2-vinlypyridine) and hydrophobic polydimethylsiloxane.…”

Preparation of Edible Non-wettable Coating with Soybean Wax for Repelling Liquid Foods with Little Residue

“…Food adhesion problems could be effectively alleviated by using a superhydrophobic surface. Superhydrophobic surfaces have become a popular topic due to their application in oil/water separation [ 2 , 3 , 4 ], anti-corrosion [ 5 ], drag reduction [ 6 ], reproductive medicine and cryobiology [ 7 ] et al Superhydrophobic surfaces, characterized by high apparent contact angles (> 150°) and low contact angle hysteresis (the difference between the advancing and receding contact angles, which could lead to a low sliding angle), have tremendous practical applications, including self-cleaning and drag reduction. The non-wetting coatings could eliminate liquid food residue, avoiding the adhesion of viscous liquid to packaging material [ 8 , 9 , 10 , 11 , 12 , 13 , 14 ].…”
