Sammendrag
The strength of ice adhesion is underpinned by the atomistic interactions at the real contact area between ice and its substrate. As such, deciphering the intrinsic ice adhesion strength at the real ice-substrate contacting area is key to the understanding of the anti-icing performances of different icephobic surfaces. The seminar will focus on utilizing molecular dynamics simulations to probe the atomistic ice interactions with different substrates of varied inter-atomic interaction potentials, and to gain insights on the interesting impacts of an amorphous quasi-liquid water layer on ice adhesion as well as different ice rupturing modes from the substrate at the nanoscale. The relevant experimental fabrication of passive anti-icing materials will also be presented, demonstrating an effective scale-crossing material design approach for surface icephobicity.
