Patent attributes
Coating compositions comprising perfluoroalkyl metallo and non-metallo perfluoro-phthalocyanine compounds and associated coating methods are provided by the present invention. Perfluoroalkyl metallo and non-metallo perfluoro-phthalocyanine compounds are suitable for use as functional coatings and may be optionally combined with conductive polymers. The functional properties imparted generally include one or more of chemical resistance, thermal resistance, biological and chemical non-stick surface behavior, electrochromism, variable electromagnetic field signatures, and/or non-linear optical properties. Advantages of the disclosed perfluoroalkyl metallo and non-metallo perfluoro-phthalocyanine coatings include the fact that an inert uninterrupted fluorinated surface provides for improved hydrophobic properties at the periphery while exhibiting improved hydrophilicity at the center, which in turn results in one or more of the following properties: variable optical, electric and magnetic properties; enhanced durability; and enhanced resistance to chemical and biological surface contamination.
