“…The same effect was achieved by treating cotton fabrics by a combination of silicon precursor TEOS and fluorocarbon polymer (Yeh et al, 2007). The significant enhancement of superoleophobicity by the deposition of silica nanoparticles with a thin fluorination coating on the surface of the particles is attributed to the following facts: (i) surface fluorination (impact on surface tension), (ii) surface topography (roughness), and (iii) creation of bionic surface hierarchically combined with nano/submicron architecture (Hsieh et al, 2010). Gonçalves has prepared superhydrophobic cellulose nano composites by employing amorphous silica particles as a mean to enhance surface roughness and perfluoro moieties for reduction of surface energy.…”

“…It was reported that trifluoromethyl group (CF 3 )-terminated flat surfaces with the lowest surface energy exhibited the highest WCA of 110∼120° [41][42][43]. The combination of surface chemical composition and rough structure is a key factor determining superhydrophobic surfaces.…”

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.

“…Methods used to create rough aluminum surfaces include anodic oxidization [98,103], sand-blasting, and electrolytic etching [108]. Nowadays, microstructured surfaces are usually fabricated by microfabrication methods, for example, micro-hoodoo structures on silicon wafer [97], hierarchical silica sphere stacking layers [99], ion track etched silica film [100], and re-entrant structures on PDMS [102]. The bonding of the fluorinated chemical layer is done by either coating [98,102] or chemical vapor deposition (CVD).…”
