The construction and application of superoleophobic surfaces have aroused worldwide interest during the past few years. These surfaces are of great significance not only for fundamental research but also for various practical applications in self-cleaning, oil-repellent coatings, and antibioadhesion. The unique properties of polymers have made them one of the most important materials for constructing superoleophobic materials. This article reviews recent developments in the design, fabrication, and application of polymeric superoleophobic surfaces.

“…Superhydrophobic surfaces like lotus leaves have a water contact angle (WCA) bigger than 150°which could be prepared by the cooperation of a low surface energy material and a rough surface structure [24][25][26]. It could be understandable that fluoropolymer/silica nanocomposites can be used to fabricate superhydrophobic surfaces because of the combination of low surface energy caused by fluoropolymer and rough surface structures due to nano-silica particles [8,15,[27][28][29]. Superhydrophobic surfaces on textiles subtrates have typical characteristics like flexibility, breathability, and light weight, attracting more and more attention.…”

A fluoropolymer/silica (FP/SiO 2 ) organic-inorganic nanocomposite was synthesized by copolymerization of butyl acrylate (BA), methyl methacrylate (MMA), 2-hydroxyethyl acrylate (HEA), and dodecafluoroheptyl methacrylate (DFMA) based on vinyl nano-silica (V-SiO 2 ) using emulsion polymerization. The V-SiO 2 was prepared via water-based solgel reaction with vinyl trimethoxy silane (VTMS) as the precursor in the presence of the composite surfactant. The preparation of V-SiO 2 , influence of the composite surfactant on VSiO 2 , effect of composite emulsifier on the properties of FP/ SiO 2 , and the formation of the FP/SiO 2 nanocomposite were analyzed. The resulting V-SiO 2 and FP/SiO 2 were characterized by particle size analyzer, transmission electron microscopy (TEM), Fourier-transform infrared spectrometry (FTIR), and X-ray photoelectron spectroscopy (XPS). The obtained FP/ SiO 2 nanocomposites were applied to coat onto the flexible polyester fabrics by dip-pad-cure process. The results showed that the V-SiO 2 nanoparticles had been introduced into the FP/ SiO 2 nanocomposites and superhydrophobic polyester surfaces were achieved by the cooperation of the rough surface structure provided by the silica nanoparticles and the low surface energy caused by fluoropolymer.

“…The micro/nano size TiO 2 gels deposited on the wood surface were the reason why the treated acacia hybrid wood displayed very high hydrophobic properties after impregnation with TiO 2 gel. The phenomena can be inferred by an explanation that the deposition of TiO 2 on the wood surface is capable of offering a secondary roughness, providing an air layer in order to prevent water drop penetrations into the lumina of wood (Hsieh et al 2011). …”

TiO 2 -treated acacia hybrid (Acacia mangium x auriculiformis) wood was fabricated by combined pressure-impregnation and hydrothermal posttreatment. The wettability and microstructure morphology, as well as the crystalline structure of the titanium dioxide (TiO 2 ) gels of the TiO 2 -treated wood, were studied. Contact angle measurements of the blank wood and the TiO 2 -treated wood indicated a significant increase in hydrophobicity, with contact angles of above 150° in treated samples. Furthermore, the water-resistant property of the treated wood was quite stable, even after immersion in boiling water. Field emission scanning electron microscopy (FE-SEM) results showed that the microstructure morphology and the size of TiO 2 gels on the wood surface were dependent on the pH of the post-treatment solutions. Additionally, the presence of amorphous TiO 2 gels was indicated by X-ray diffraction (XRD) analysis. The results of this study indicate that combined pressure-impregnation and hydrothermal post-treatment can create a hydrophobic wood-TiO 2 composite.
