    Abstract: Provided are surfacing films that have a surface layer having opposed first and second major surfaces, the first major surface comprising a fluoropolymer surface and the second major surface optionally comprising a nanostructured surface. A printed layer can be disposed on the second major surface and can be at least partially embedded in the nanostructured surface, if present. As a further option, the fluoropolymer surface can be microreplicated to provide a frictional surface and/or provide aerodynamic drag reduction on aircraft structures. Optionally, the delamination peel strength of the surface layer from the remaining layers can be greater than the tensile strength of the surface layer.

    Abstract: Crosslinked silicone foams are provided that can be substantially free of chemical blowing agents or byproducts thereof. These foams can be prepared from polymerizable silicone compositions that include an MQ-water cluster including a silicate MQ resin and a quantity of water dispersed in the silicate MQ resin and a silicone fluid, wherein the MQ-water cluster and silicone fluid collectively provide a inverted emulsion having a continuous and a discontinuous phase, the continuous phase including the silicone fluid and the discontinuous phase including the MQ-water cluster. The foams can be made by dispersing water into a silicate MQ resin to provide an MQ-water cluster; dispersing the stabilized MQ-water cluster into a silicone fluid to obtain an inverted silicone emulsion having the MQ-water cluster as a discontinuous phase and the silicone fluid as a continuous phase; foaming the silicone emulsion by evolving the water in the MQ-water cluster to provide a cellular structure; and polymerizing the silicone emulsion.
