Methods for coating and modifying surfaces and interfaces of substrates of arbitrary shape

总结

Lead Inventors: Peng Wang, Ph.D., Jeffrey T. Koberstein Ph.D.Problem or Unmet Need:It is desirable to design and control the structure and properties of surfaces and interfaces without affecting a material's bulk properties. Few current techniques for surface modification, however, allow for specific chemical and structural control at molecular dimensions. In addition, many methods under development for surface modification are not readily suited to industrial application and scale up. The present invention is useful as a means to coat monolayer films of photoactive polymers onto substrates of arbitrary shape with supercritical carbon dioxide and other supercritical solvents. This approach provides molecular-based methods and processes that can be used to control the chemical and physical nature of surfaces and interfaces. These coatings allow the possibility of functionalizing polymer surfaces through modifying functional groups in a homogenous way and controlling the spatial distributions of surface functional groups.
