Transparent superhydrophobic coatings from amphiphilic-fluorinated block copolymers synthesized by aqueous polymerization-induced self-assembly

Abstract

Preparation of transparent and superhydrophobic coatings by co-deposition of an aqueous solution of an amphiphilic fluorinated block copolymer with silica was developed.

High‐Performance Materials for 3D Printing in Chemical Synthesis Applications

“…Due to the inherent nano-/microstructure throughout the whole bulk material the superhydrophobic properties are insensitive to abrasion. This is a major advantage over state-of-the-art superhydrophobic coatings such as deposited nanoparticles, [66][67][68] etched, [69,70] anodized, [71] or imprinted surfaces [72] or surfaces made by phase-separation effects [73,74] which are often fragile single layers and very sensitive to abrasion. Since the pore size of Fluoropor foam is smaller than the wavelength of visible light the material is optically transparent (see Figure 4a) making these materials applicable for real-world applications like window coatings, etc.…”

Designing superhydrophobic surface based on fluoropolymer–silica nanocomposite via RAFT‐mediated polymerization‐induced self‐assembly

“…Ouhib et al have recently reported an approach to develop SHS using SNP and fluorinated amphiphilic BCP prepared via an RAFT-mediated PISA process. 38 However in that case, the mixture of SNP and BCP was able to show superhydrophobicity only after annealing at 150 8C.…”

“…The polymerization of fluorinated monomer by such a process was recently reported by Zhou et al However, the formation of fluoropolymer particles was very much dependent on the pH of the medium. Ouhib et al have recently reported an approach to develop SHS using SNP and fluorinated amphiphilic BCP prepared via an RAFT‐mediated PISA process . However in that case, the mixture of SNP and BCP was able to show superhydrophobicity only after annealing at ∼150 °C.…”

Synthesis and surface properties of amphiphilic fluorine‐containing diblock copolymers

“…A lot of approaches for both applying roughness and structuring the surface as well as for covering the surface with different compounds with low surface energy have been proposed. Up to now, a variety of rough surfaces have been prepared using chemical etching, 6 lithography, 7 laser microstructuring, 8 applying nanoparticles, [9][10][11][12] or nanofibers 13 of different nature, mechanical treatment such as pressing rough templates to the substrate 14 and many other methods, such as depositing candle soot on a substrate. 15 Substances containing nonpolar groups such as CH 2 , CH 3 , CF 2 , CF 3 , can be used before or after roughening to achieve low surface energy.…”
