Latest Patents

One of Joyce's latest patents is the "Laser transfer process." This invention relates to a method for producing a smooth continuous and adherent pressure bonded or cold welded layer of a metal-containing composite on a base or target material through the driving force of a pulsed laser. The method includes selecting a laser transparent substrate, applying a thin laser absorptive polymeric film characterized by a high optical coefficient of absorption to the wavelength of the laser, and applying the metal-containing composite to the absorptive polymeric film. The composite is a multilayered structure comprising laser absorptive polymer, gold, nickel, and gold-flash. The pulsed laser energy is directed through the transparent substrate toward the composite, causing heating and vaporization of the polymeric film, which propels the composite onto the base or target material.

Another significant patent involves an "Inert electrode comprising a conductive coating polymer blend." The compound ortho-methoxyaniline (o-anisidine) can be polymerized to produce polyanisidine, a soluble polymer with high electrical conductivity. This technology has been enhanced to yield 47 percent with no apparent loss in electrical conductivity. Polyanisidine can be blended with various other polymers, resulting in stable, flexible films and fibers with adjustable electrical resistance values. The applicability of this technology has been demonstrated through the construction of devices such as a color-changing switching device, an inert polymer electrode, and an electromagnetically shielded connector.
