  • Patent number: 9011710
    Abstract: Methods are disclosed for synthesizing nanocomposite materials including ferromagnetic nanoparticles with polymer shells formed by controlled surface polymerization. The polymer shells prevent the nanoparticles from forming agglomerates and preserve the size dispersion of the nanoparticles. The nanocomposite particles can be further networked in suitable polymer hosts to tune mechanical, optical, and thermal properties of the final composite polymer system. An exemplary method includes forming a polymer shell on a nanoparticle surface by adding molecules of at least one monomer and optionally of at least one tethering agent to the nanoparticles, and then exposing to electromagnetic radiation at a wavelength selected to induce bonding between the nanoparticle and the molecules, to form a polymer shell bonded to the particle and optionally to a polymer host matrix. The nanocomposite materials can be used in various magneto-optic applications.

  • Patent number: 8323749
    Abstract: The invention relates to a process for applying a liquid UV-curable primer sealant to natural stone tiles and related articles followed immediately by the exposure to a requisite amount of low intensity UVA-type UV radiation to partially cure the primer sealant. The partial curing, or pre-setting, of the primer sealant enables control of the ultimate depth of penetration of the primer sealer into the natural stone tiles and natural stone articles of which many examples are quite porous. Because the low level UV irradiation is instantaneous after the primer sealant application the level of primer sealant penetration into the natural stone surface is regulated. The pre-curing of the primer sealant is conducted to intentionally solidify or immobilize the sealant that has actually penetrated into the natural stone surface. The uppermost layers of the primer sealant are left in a semi-liquid or uncured state to allow for wetting and intermingling by the top sealant once it is applied.

The resin binder in the transition layer migrates into pockets and pores in the substrate face surface to create mechanical locks when the resin binder is cured. These locks, in addition to chemical bonding, serve to permanently affix the cured resin binder as a surface cladding to the substrate. Initiators may be added to the resin binder to promote thermal and/or UV radiation cures thereof.

  • Publication number: 20020064713
    Abstract: A method of forming a strong phase shift mask substrate. A substrate is introduced into a deposition chamber. The substrate has a surface, and is transmissive to electromagnetic radiation of a desired wavelength. A first precursor having at least a first component and a second component is introduced, and covers the surface of the substrate to a thickness of one molecular layer of the first precursor. The excess of the first precursor is removed from within the deposition chamber. A second precursor having at least a third component and a fourth component is introduced. The second precursor attaches to the first precursor. The excess of the second precursor is removed from within the deposition chamber. The first precursor is reacted with the second precursor to form a first monolayer of the first component and the third component on the surface of the substrate. The first monolayer is operable to cause a first phase shift in the electromagnetic radiation of the desire wavelength.

  • Patent number: 6210537
    Abstract: The present invention provides electronically conducting polymer films formed from photosensitive formulations of pyrrole and an electron acceptor that have been selectively exposed to UV light, laser light, or electron beams. The formulations may include photoinitiators, flexibilizers, solvents and the like. These solutions can be used in applications including printed circuit boards and through-hole plating and enable direct metallization processes on non-conducting substrates. After forming the conductive polymer patterns, a printed wiring board can be formed by sensitizing the polymer with palladium and electrolytically depositing copper.
