摘要： Curable compositions are provided for forming highly lubricious and long-lasting surfaces with optical clarity useful, for example, in optical applications in harsh environmental conditions. In some aspects, the curable formulations include an end-group modified perfluoropolyether (PFPE), a fluorinated lubricant, and a compatibilizer. The mixtures are curable to form a solid having an exposed surface. In some aspects, the fluorinated lubricant is chemically and physically matched to the resin such that, when cured, at least a portion of the fluorinated lubricant spontaneously forms a lubricious surface on the exposed surface. In some aspects, the compatibilizer is present in an amount sufficient to make the curable mixture miscible and to make the solid optically transparent while still spontaneously forming the lubricious surface. The lubricious surface can also be self-replenishing such that, when the lubricant is removed from the exposed surface, additional lubricant migrates to the surface to replenish the lubricious overlayer.

摘要： The disclosure relates to sidechain functionalized organosiloxane compounds comprising polyalkyleneoxide (POA) and/or polyalkyleneoxide coupled zwitterionic moieties with various other modular side chains including reactive and or non-reactive groups. The present disclosure further also pertains to ice-phobic polymer formulations capable of curing on a substrate to form a surface that is ice-phobic, resistant to ice formation, and/or resistant to ice adhesion. The disclosed ice-phobic polymer formulations comprise one or more disclosed sidechain functionalized organosiloxane compound, one or more binder resin, and/or one or more lubricating liquid. The present disclosure further relates to articles comprising the disclosed ice-phobic polymer compositions, thereby providing articles having ice-phobic properties. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.
