Background

Nanophase Technologies is an industry-leading nanocrystalline materials innovator and manufacturer with an integrated family of nanomaterial technologies. The entire focus of Nanophase is nanotechnology, with two distinct and patented processes for the preparation and commercial manufacturing of nanopowder metal oxides i.e. Aluminum Oxide, Zinc Oxide, Cerium Oxide, Titanium Dioxide, and several others. Nanophase Technologies Corporation has developed a process, Discrete Particle Encapsulation, to coat the surface of its nanoparticles with a thin polymeric shell that enables compatibility of the particles with a wide variety of fluids, resins and polymers. Also, Nanophase has developed technology to permit the dispersion of its nanoparticles in water and a variety of polar and non-polar organic fluids. This allows Nanophase to supply concentrated, ready-to-use nanoparticle dispersions, eliminating the need for customers to disperse the nanoparticles themselves. Nanophase’s family of integrated technologies economically produces nanocrystalline materials, and then nanoengineers those materials to fit a customer need.

Applications and Markets

Nanophase produces engineered nanomaterial products for a variety of diverse markets: personal care, sunscreens, abrasion-resistant applications, environmental catalysts, antimicrobial products, and a variety of ultra-fine polishing applications, including semiconductor wafers, hard disk drives, and optics. Various applications include wood preservation, anti-fouling and anti-microbial coatings, fuel cells, catalytic converters, UV-attenuation coatings, scratch resistant coatings, charge dissipating coatings, deodorant/antiperspirants, depilatory/shaving products, and others. In parallel, new markets and applications are constantly being developed.

Textile Fibers

Nanoparticles have been incorporated into textile products such as nylon, polypropylene and other polymers to provide long-term antimicrobial character even in harsh environments and after extensive thermal cycling. The need for minimizing or eliminating microbial growth on a variety of textile-based substrates has become a major topic of discussion in numerous industries, including healthcare, home furnishings, filtration and apparel, among others.

NanoTek® Zinc Oxide, Copper Oxide or Doped Zinc Oxides

NanoTek® zinc oxide, copper oxide or doped zinc oxides, due to the small particle size, can be readily incorporated into synthetic fibers such as Nylon prior to extrusion through spinnerets to impart antimicrobial activity with minimal effects on color and clarity, surface gloss, physical properties and melt flow properties. NanoTek® products may also be incorporated into coatings that can be applied to staple fibers to impart antimicrobial activity. Such applications include carpet fibers, water filters of various types, fabrics for use in healthcare facilities and various institutions, activewear and other apparel, home furnishings and a variety of non-woven applications including the transportation and bedding industries. Zinc oxide is FDA approved for skin contact applications and NanoTek® zinc oxide is produced under cGMP conditions and is approved as an active ingredient for personal care products.
