abstract

  • 2016 American Chemical Society. Amphiphilic hyperbranched fluoropolymer coatings incorporating liquid crystalline moieties and poly(ethylene glycol) cross-linkers were found to demonstrate noteworthy anti-icing properties. A series of amphiphilic networks was synthesized through variation of the polymer molecular weights and hydrophilic/hydrophobic component ratios. These innovative materials show a remarkable reduction in the free water melting transition (Tm) temperature (10 C), measured by differential scanning calorimetry, and an increase in water contact angle for dry and water-swollen systems. The addition of this ordered parameter generated a unique coating topography, which can be visualized via polarized optical microscopy and 3D optical microscopy, while maintaining an overall macroscopic homogeneity.
