“…As expected, the surface energies of the resins decreased with increasing FAS content and reached a saturation value of ~19.8 mJ/m². Compounds that contain fluorine are generally expensive and are not very soluble in common organic solvents [ 33 ]. Considering cost and solubility, 2 mol % FAS was determined as the optimal concentration for resin synthesis.…”

Fabrication of Robust Superhydrophobic Surfaces with Dual-Curing Siloxane Resin and Controlled Dispersion of Nanoparticles

We developed a simple method for the fabrication of superhydrophobic surfaces on various substrates using spray coating. The fabrication method started with the blending of a modified hydrophobic siloxane binder, silica nanoparticles, and a volatile solvent by sonication. The mixture was spray-coated on various surfaces such as slide glass, paper, metal and fabric, forming a rough surface comprising silica particles dispersed in a hydrophobic binder. Surface hydrophobicity was affected by the surface energy of the binder and the degree of roughness. Therefore, we realized a superhydrophobic surface by controlling these two factors. The hydrophobicity of the siloxane binder was determined by the treatment of fluorine silane; the roughness was controlled by the amount of coated materials and sonication time. Thus, using the spray coating method, we obtained a superhydrophobic surface that was mechanically durable, thermally stable, and chemically resistant.

“…The copolymer was synthesized by the method described in detail elsewhere: 204 g (0.36 mol) of N ‐(3‐(triethoxysilyl)propyl)perfluoroheptane amide and 85 mL (0.36 mol) of phenyltriethoxysilane and 87 mL (0.36 mol) of 3‐aminopropyltriethoxysilane were added to 1200 mL (16.2 mol) of trifluoroacetic acid. The mixture was stirredat room temperature for 11 h until complete disappearance of ethoxy groups signals in 1 H NMR spectrum.…”

In this work, approach to use of noncovalently modified carbon nanotubes is given for preparation of functional hybrid polymeric composite materials (HPCM) based on epoxy resin. Conductive glass-fiber plastics with resistivity in transverse and lengthwise direction 9.0Á3 10 2 and 30-50 Ohm cm, respectively, were obtained. The tetrafluoroethylene telomer and fluorocontaining organosilicon copolymer with amino groups were used as modifiers for carbon nanotubes. Thermal, electrical, and mechanical properties of the obtained materials were studied. The mechanism of the effect of noncovalent modification of carbon nanotubes on functional properties of HPCM was discussed. It was found, that type of modifier significantly affects the level of functional properties. The use of fluorocontaining organosilicon copolymer is more optimal in comparison with tetrafluoroethylene telomer. Thus, HPCM with carbon-fiber filler and this modifier has higher electrical conductivity and lightning strike resistance in comparison with nonmodified HPCM. This approach is promising to impart antistatic properties for glass-fiber plastics and increase lightning resistance of carbonfiber plastics.

Porous films were prepared on the base of the cardo polyimide soluble in organic solvents and modified with fluorocontaining organosilicon copolymers. The fluorinated organosilicon copolymers with various molecular weights were used as hydrophobic modifiers. It was shown that addition of modifiers leads to formation of porous structure with monomodal size distribution. Modification of the polyimide with copolymers in combination with the surface structuring resulted in formation of the highly hydrophobic porous films with contact angle 137°.
