  • Patent number: 5897918
    Abstract: A faster and more efficient method for applying ultra thin films to substrate surfaces is disclosed. The method comprises heating a film forming composition comprising amphiphilic molecules to a liquid state, immersing the substrate surface in the heated liquid composition to heat the surface, and washing away the excess composition. For surfaces that ordinarily have insufficient or no chemical moieties reactive with the amphiphilic molecules, the immersion in the heated composition causes the substrate to become porous and expose previously unavailable chemically reactive moieties in the surface matrix. The amphiphilic molecules then self-assemble, chemically bond to the surface matrix and self-polymerize with each other and with other surface matrix-bound and/or surface-bound molecules to form the ultra thin surface film. The method is also faster and more efficient for coating non porous and metal surfaces.

  • Patent number: 5300561
    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.

  • Patent number: 5219654
    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. wherein the carrier stabilizes the film forming substance, and inhibits diffusion of moisture and oxygen into the composition which minimizes deterioration of the film forming substance, and also minimizes undesirable formation of agglomerations of such substance and 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 after which the excess composition is then washed away.

  • Patent number: 5173365
    Abstract: An ultra-thin, self-assembling molecular film has thickness, length and width dimensions. Ampliphilic molecules in the film are ordered in the thickness dimension, and are arranged in crystals that are aligned in both the length and width dimensions. This molecular alignment in all three film dimensions provides a film having more uniform properties.
