  • Patent number: 5204126
    Abstract: A film forming composition including a film forming substance having amphiphilic molecules and being dispersed in a gel-like carrier having a non-liquid state below about 20.degree. C. The carrier stabilizes the film forming substance, and inhibits diffusion of moisture and oxygen into the composition. This minimizes deterioration of the film forming substance, and also minimizes undesirable formation of agglomerations of such substance. When the composition is applied to a surface, an ultra thin substantially continuous film of substantially uniform thickness forms spontaneously and attaches to the surface. The excess composition is then washed away.
    Type: Grant
    Filed: October 10, 1991
    Date of Patent: April 20, 1993
    Assignee: NanoFilm Corporation
    Inventors: Brij P. Singh, Raj Subramaniam
  • Patent number: 5166000
    Abstract: A solution of amphiphilic molecules and water is atomized to form a mist of droplets which are deposited on a substrate surface to completely cover same with a coating of the solution. The amphiphilic molecules in the coating self-assemble on the surface into a continuous thin film that is less than 500 nanometers thick. The water is evaporated from the coating to leave only the film chemically bonded to the surface.
