摘要:
A process for producing metal plated paths on a solid substrate of the kind which has polar functional groups at its surface utilizes a self-assembling monomolecular film that is chemically adsorbed on the substrate's surface. The solid substrate may, for example, be an insulator of the kind used for substrates in printed circuitry or may, as another example, be a semiconductor of the kind used in semiconductor microcircuitry. The chemical reactivity in regions of the ultra-thin film is altered to produce a desired pattern in the film. A catalytic precursor which adheres only to those regions of the film having enough reactivity to bind the catalyst is applied to the film's surface. The catalyst coated structure is then immersed in an electrolers plating bath where metal plates onto the regions activated by the catalyst.

Tubules which contain an active agent in their lumen and compositions containing such microtubules are effective for providing a slow, controlled release of the active agent. Such microtubules are useful in the production of coating compositions for the protection of surfaces coming into contact with water, adhesive resins for the production of laminated wood products, and devices for dispensing pesticides.

Tubular, spheroidal, and helical lipid microstructures are individually clad with a metal coat deposited on the microstructures by an electroless plating bath. In metal cladding the microstructures, the surfaces of the lipid microstructures are sensitized by adsorption thereon of a catalytic precursor which enables metal from the electroless plating bath to deposit upon and adhere to the sensitized surface. The metal plate is electrically conductive and may also be magnetic. A composite material is produced by embedding the metal clad microstructures in a matrix of a polymer such as an epoxy or a polyurethane.

Lipid microtubules having a controlled bilayer structure and high aspect io are formed in a methanol/ethanol/water solvent system. The lipid microtubules may then be catalyzed (e.g., with a palladium/tin catalyst) in an acidified catalytic bath having no more than about 30 g of catalytic salts. These catalyzed microtubules are then metallized using a diluted plating bath with replenishment of the plating bath as needed to obtain the desired metallization thickness.

A field emitter array comprises an array of aligned metallic, conductive rotubules extending from a conductive base. The array is typically made by cutting a matrix comprising the aligned microtubules into sections, usually normal to the tubule alignment axis. One end surface of a section is etched or otherwise treated to remove the matrix, but not the tubules. That end surface is then provided with a conductive coating and fixed to a contact. The other end surface of that section is then also treated to remove the matrix material and leave the tubules extending from the conductive metal base. Field emitter arrays made according to the present invention provide a greater brightness than conventional field emitter arrays.

Diacetylinic phosophocholines have distinctly different endothermic and exothermic transition temperatures. Lipid tubules are formed by hydrating a diacetylinic phosphocholine at a temperature above its endothermic transition temperature. The hydrated lipid is then cooled slowly to a formation temperature 1.degree. to 10.degree. C. below the exothermic transition temperature to form tubule structures. The tubules structures can be polymerized to form permanent tubules. The tubules can be used in the same manner as a liposome vesicle or they can be metal coated for a variety of applications.

The present invention is directed to a method for making a conformal antenna on a surface by providing a composition comprising a polymer matrix and a plurality of metalized tubules and applying the composition to the surface as two parallel wires connected at their ends to make a closed loop with one of the parallel wires broken in the middle. Also disclosed is an alternate method for making a conformal antenna on a surface by spraying a first material comprising a polymer matrix onto the surface and simultaneously spraying a second material comprising a plurality of metalized tubules and a coagulant onto the surface, wherein the first and second materials mix together during the spraying. A further method for making a conformal antenna includes spraying a first material comprising a polymer matrix and a plurality of metalized tubules onto the surface and simultaneously spraying a second material comprising an aqueous electroless plating bath onto the surface, wherein the first and second materials mix together during the spraying.
