Abstract: An anti-icing coating is provided having low interfacial toughness (LIT) with ice. The anti-icing coating includes a polymer and a plasticizing agent. A thickness of the anti-icing coating may be less than or equal to about 100 micrometers (?m). Further, the anti-icing coating has an interfacial toughness (?ice) with ice of less than or equal to about 1 J/m2. Such an anti-icing coating may be applied to a substrate or surface of a device on which ice may form, such as aircraft, vehicles, marine vessels, outdoor equipment, snow or ice removal equipment, recreational equipment, wind turbines, telecommunications equipment, power lines, and the like. Methods of forming such anti-icing coatings are also provided.

Abstract: A protective device and method of design to protect against multiple blast and impact events for use in any application in which a delicate target has to be protected. The protective device for mitigating the effects of blast or impact employs a first layer having a first acoustic impedance and a second layer having a second acoustic impedance. The second acoustic impedance is different than the first acoustic impedance. The second layer is proximate to the first layer. The first layer and the second layer are chosen collectively to tune the stress waves from the blast or impact events to one or more specific tuned frequencies. A third layer of a visco-elastic material is employed having a critical damping frequency that matches one or more specific tuned frequencies to dissipate the stress waves of the blast and impact event. The third layer is proximate to the second layer.
