Enhancement of icephobic properties based on UV-curable fluorosilicone copolymer films

Abstract

UV-curable fluorosilicone triblock methacrylate copolymer films were prepared for icephobic applications. Water droplets could rebound from the film surfaces at −15 °C due to their high receding contact angles, avoiding ice accretion.

Icephobic Durability of Branched PDMS Slippage Coatings Co-Cross-Linked by Functionalized POSS

“…Ice adhesion strength, which was denominated as ice shear strength in this study to evaluate the horizontal shear strength of ice detaching from the coating surfaces it adhered to, was measured using a custom-built apparatus according to our previous reports. − ,, Typically, a stainless steel sheet with the as-prepared coating was placed onto the Peltier plate, on which a hollow glass cylinder (inner diameter of 9.84 mm) hydrophobically treated with 1 H ,1 H ,2 H ,2 H -perfluorooctyl trichlorosilane was placed. Then, 450 μL of deionized water was pipetted in the cylinder, and left in a chamber with a stream of dry N 2 at a temperature of −15 °C for more than 3 h to ensure its total freezing that adhered to the coating surface.…”

Material Strategies for Ice Accretion Prevention and Easy Removal

“…Li et al developed a UV-curable films composed of thiol-terminated fluorosilicone methacrylate triblock copolymer, thiol-functionalized PDMS and octavinyl-polyhedral oligomeric silsesquioxanes. The perfluoroalkyl side group presented in crystalline structure and endowed coating with higher hydrophobicity and low ice adhesion . The results showed that ice shear strength was reduced by the synergistic effect of the fluorine and silicone .…”

“…The perfluoroalkyl side group presented in crystalline structure and endowed coating with higher hydrophobicity and low ice adhesion. 105 The results showed that ice shear strength was reduced by the synergistic effect of the fluorine and silicone. 106 Surface modification by using fluorine or silicone regents can effectively reduce the ice adhesion strength to about 200− 300 kPa, but the adhesion of ice was too high to remove ice by wind or gravity.…”

Waterborne UV-curable comb-shaped (meth)acrylate graft copolymer containing long fluorinated and/or polysiloxane side chains

“…Fluorinated polymers and siloxane polymers are two famous families of materials with extremely low surface energy, outstanding water and oil repellency, excellent thermal and chemical properties, photochemical stability. [6][7][8][9][10][11][12][13][14][15][16][17][18] Fluorosilicone materials, which integrating the advantages of both uorinated polymers and silicone-based polymers, create synergistic effects of uorine and silicon. 7 The synergistic effects of uorine and silicon can improve the comprehensive performance of the materials, especially the surface property.…”
