Ice-phobic coatings are extremely promising materials for applications in cold environments, such as aircraft wings, power lines, and radar towers. However, no such surface in nature shows perfect ice-phobicity. By reducing ice adhesion to these surfaces, ice can easily be removed by natural forces before it causes structural damage. Polydimethylsiloxane (PDMS) is a commonly used polymer with low surface energy and extremely low glass transition temperature, which makes it to an ideal matrix to fabricate ice-phobic coatings. In this work, ice-phobic coatings were fabricated by PDMS based thiol-ene resins containing SiO2 nanoparticles via spray deposition method and sequential photopolymerization.  Scanning electron microscopy images show the multiscale topography of the surface. Ice adhesion force was measured by normal stress and critical shear stress between ice and the solid surface.
