The icephobicity comparison of polysiloxane modified hydrophobic and superhydrophobic surfaces under condensing environments
Abstract(#br)Four polydimethylsiloxane (PDMS) coatings with different surface free energies have been prepared and applied to smooth and roughened aluminum plates to form hydrophobic and superhydrophobic surfaces. Their surface wettability in terms of water contact angle (CA), sliding angle (SA) and water droplet impact dynamics was studied under an ambient (50% relative humidity, RH at 25\u003cce:hsp sp=\"0.25\"/\u003e°C) and three different condensing environments (low, highly and extremely condensing, i.e. 30%, 60% and 90% RH at −10\u003cce:hsp sp=\"0.25\"/\u003e°C).
