AB  - Ice readily sheds from weak oil-swollen polymer gels but tends to adhere to 
      mechanically robust coatings. This paper reports bilayer coatings that 
      simultaneously possess high bulk hardness but low ice adhesion. These coatings 
      are prepared by cocuring a triisocyanate, P#'-g-PDMS [a methacrylate polyol 
      bearing poly(dimethylsiloxane) (PDMS) side chains with # being 1, 2, or 3 and g 
      denoting graft], and optionally a methacrylate polyol P#. The self-assembly of 
      the system during coating formation yields a PDMS brush layer on the surface of 
      the cross-linked polyurethane matrix. After the surface PDMS layer is lubricated 
      with a silicone oil, this coating exhibits an ice adhesion tau that is 10 000-fold 
      lower than that of a triisocyanate/P# coating. Ice slides under its own weight on 
      such a coating at a tilt angle of 3 degrees . Yet, the coating matrix is harder than 
      poly(ethylene terephthalate), a widely used plastic. Additionally, such a coating 
      maintains its low tau values for more than 10 consecutive icing/deicing cycles. 
      Subsequent increases in tau are reversed by allowing time for the replenishment of 
      the depleted surface lubricant with that released from the coating matrix. This 
      design opens the door for effective yet hard ice-shedding polymer coatings.
