Highly fluorinated phosphonium ionic liquids: novel media for the generation of superhydrophobic coatings

Abstract

A new class of highly fluorinated phosphonium ionic liquids (HFPILs) that are thermally stable, non-volatile, tuneable small molecules has been synthesized; they are uniquely suited for creating novel superhydrophobic coatings, offering a new paradigm in the application of ionic liquids.

Photoinduced Carbene Generation from Diazirine Modified Task Specific Phosphonium Salts To Prepare Robust Hydrophobic Coatings

“…14,15 The advantage the HFPS systems possess, compared to other strategies, is that the phosphonium salts can be readily modified using selective substitution chemistry on the phosphorus center, which is much more difficult to obtain in related C-or Si-centered and even polymer systems. In this way, using a small number of simple quantitative transformations one can impart specific functionality onto the cation.…”

Thermophysical Characterization of Ionic Liquids Based on the Perfluorobutanesulfonate Anion: Experimental and Soft‐SAFT Modeling Results

“…In this work, FILs are considered as ionic liquids with fluorinated alkyl chains with at least four carbon atoms in the cation and/or the anion . So far, the majority of the studies for this type of ILs focus on their synthesis and basic characterization . The advanced main applications envisaged for FILs are centered on reaction media or solvents, surfactants, phase transfer catalysis, electrolytes in high‐energy storage devices, electrolytes in dye‐sensitized solar cells, liquid crystals for optoelectronics, superhydrophobic coatings, gas separation, and extractive platforms .…”

Micro–nano hierarchically structured nylon 6,6 surfaces with unique wettability

“…Because of the unique wetting behavior, both superhydrophobic and superhydrophilic surfaces are promising for many applications, such as self-cleaning articles [12][13][14], corrosion inhibition [15], drag reduction [16], microfluidic devices [17,18] and biological apparatus [19][20][21][22][23]. Up till now, numerous methods and techniques have been developed to produce surfaces with unique wettability [24][25][26][27][28][29][30][31][32][33][34][35][36][37]. In contrast to many multiple, time-consuming, chemically harsh processes, we now provide a facile way to fabricate micro-nano hierarchically structured superhydrophilic surfaces by phase separation.…”
