Reduction of ice adhesion on nanostructured and nanoscale slippery surfaces

Ice nucleation and accretion on structural surfaces are sources of major safety operational concerns in many industries including aviation renewable energy. Common methods for tackling these active ones such as heating, ultrasound, chemicals or passive surface coatings. In this study, we explored the ice adhesion properties slippery coated substrates by measuring shear forces required to remove a glaze block substrates. Among studied nanostructured nanoscale [i.e., superhydrophobic coating, fluoropolymer polydimethylsiloxane (PDMS) chain coating], omniphobic covalently attached liquid (SOCAL) with its flexible polymer brushes liquid-like structure significantly reduced both glass silicon surfaces. Further studies SOCAL coating roughened also demonstrated low adhesion. The reduction is attributed nature brush-like structures PDMS chains, allowing detach easily.
