Aerospace A recent study presents a new way to attain an ice-phobic polyurethane (PU) composite coating, which was fabricated by incorporating minor dosages of hybrid silica particles and silicone oil (SO) into the formulation of a commercial aerospace PU topcoat. The hybrid silica particles were synthesised by anchoring polydimethylsiloxane (PDMS) oligomers to silica microspheres. Both hybrid particles and SO amalgamate in the surface matrix of PU to induce a spread of wrinkling micro-loops over the coating. It was possible to adjourn the onset of frosting to ~ -10 ºC of from - 5.6 ºC on the aerospace PU topcoat. ...
