    Abstract: A thermally-stable cationic photoinitiator capable of flash vaporization under vacuum and temperature conditions of an available flash-evaporation chamber is selected. The photoinitiator is mixed with a cation-polymerizable monomer and/or oligomer of interest and the mixture is flash evaporated and condensed in conventional manner as a film on a cold substrate. The resulting vacuum-deposited, homogeneous layer is cured with a high-energy radiation source that causes the cationic photoinitiator to liberate acidic species that catalyze the crosslinking of the monomer/oligomer compounds in its deposited film form. As a result of the homogeneous, pinhole-free nature of the vacuum deposition process, the thin-film polymer product does not suffer from the disadvantages attendant to prior-art atmospheric processes for cationically-cured polymers. In addition, because of the versatility afforded by vacuum deposition, hybrid films of such polymers with inorganic materials are also easily manufactured in-line during the same process.

    Abstract: A high energy density, high power density capacitor having an energy density of at least about 0.5 J/cm.sup.3 is provided. The capacitor comprises a plurality of interleaved metal electrode layers separated by a polymer layer. The interleaved metal electrode layers terminate at opposite ends in a solder termination strip. The high energy density aspect of the capacitors of the invention is achieved by at least one of the following features: (a) the dielectric thickness between the interleaved metal electrode layers is a maximum of about 5 .mu.m; (b) the polymer is designed with a high dielectric constant .kappa. of at least about 3.5; (c) the metal electrode layers within the polymer layer are recessed along edges orthogonal to the solder termination strips to prevent arcing between the metal electrode layers at the edges; and (d) the resistivity of the metal electrode layers is within the range of about 10 to 500 ohms per square, or a corresponding thickness of about 200 to 30 .ANG..

    Abstract: Metal-polymer nanolaminate products are fabricated from a bulk nanolaminate material composed of thousands of alternating metal and polymer layers. The nanolaminate material is produced by a prior art ultra high speed vacuum nanotechnology process that forms metal layers separated by radiation cross linked multifunctional acrylate polymer materials. The polymer to metal ratio in the nanolaminate composite can be successfully controlled. The polymer chemistry in the nanolaminate can be varied to incorporate a broad range of functional groups. The nanolaminate products are safe to handle and are environmentally and chemically stable at least up to 250.degree. C. A change in polymer chemistry can be used to lower or enhance the thermal degradation point of the polymer material.

    Abstract: A multilayer dielectric structure is formed by vacuum depositing two-dimensional matrices of nanoparticles embedded in polymer dielectric layers that are thicker than the effective diameter of the nanoparticles, so as to produce a void-free, structured, three-dimensional lattice of nanoparticles in a polymeric dielectric material. As a result of the continuous, repeated, and controlled deposition process, each two-dimensional matrix of nanoparticles consists of a layer of uniformly distributed particles embedded in polymer and separated from adjacent matrix layers by continuous polymer dielectric layers, thus forming a precise three-dimensional nanoparticle matrix defined by the size and density of the nanoparticles in each matrix layer and by the thickness of the polymer layers between them. The resulting structured nanodielectric exhibits very high values of dielectric constant as well as high dielectric strength.

    Abstract: A coated, low-emissivity aluminum film is manufactured entirely in vacuum by depositing an aluminum layer over a substrate and then immediately coating the metal layer with a very thin protective polymeric layer. The thickness of this coating is selected to minimize absorption in the 3-15 micron wavelength. In vacuum, the metal layer is coated substantially in the absence of moisture, thereby preventing the formation of hydrated oxides that promote corrosion. The aluminum layer is preferably also passivated by in-line exposure to a plasma gas containing an oxygen-bearing component. A leveling polymeric layer may also be deposited between relatively rough substrates and the aluminum layer in order to improve the reflectivity of the resulting structures.

    Abstract: In a continuous in-vacuum process for the manufacture of a film metallized with aluminum, the aluminum layer is exposed to a passivating agent, inline, immediately after deposition and prior to rewinding of the film onto a take-up roller. Passivation is carried out by plasma treatment in an oxidizing atmosphere (oxygen, nitrogen or others). The resulting product exhibits no peel-off problems during unwinding of the take-up roller and greatly improved corrosion resistance.
