Ice formation on surfaces like wind turine blades and airplane wings is both hazardous and costly.  By chemically modifying these surfaces, they will exhbiit passive anti-icing behavior to eliminate the need for ice removal. We have taken a novel approach to this problem by introducing hydrogen-bonding to the surface modifier in order to disrupt ice formation at the interface between crystalline water and a surface through experimental and molecular modeling techniques.  In this presentation, we plan on showing how hydrogen-bonding on the surface will affect the ice structure in the bulk and at the adhesive interface as compared to more hydrophobic surfaces.  In addition, the effects of surface roughness and mixing modifier types will be discussed.
