Applied Nanotech Holdings Unveils Transparent And Electrically Conductive Substrates Using Copper-Based Metallic Mesh Technology During Printed Electronics USA 2010
AUSTIN, Texas, Nov. 30, 2010 (GLOBE NEWSWIRE) -- Applied Nanotech Holdings, Inc. (OTCBB:APNT)announced the introduction of EXCLUCENT™ , one of the most suitable potential replacements for ITO (Indium Tin Oxide) coated substrates currently used for multiple applications such as liquid crystal displays (LCDs), organic LED (OLED) displays, solar cells, touch screens, transparent antistatic and EMI shielding protectors, as well as substrates for the very promising growing industry of solid state lighting.
EXCLUCENT™ substrates on flexible transparent PET (polyethylene-terephthalate) utilizing copper-based metallic mesh are currently in volume production by an overseas manufacturer and are available for sale by Applied Nanotech, Inc. ("ANI"). ANI can provide sample EXCLUCENT™ substrates and, if necessary, develop specific applications together with potential users.
The industries currently utilizing ITO recognized some time ago that ITO is extremely problematic - suffering from price volatility and sustained high cost. Lately, the market place is constrained by a limited worldwide availability, and a resulting very high price of indium, and potentially tin in the future.Industries have been searching to find alternatives to ITO such as transparent conductive oxides, polymers, carbon nanotube inks, but at this stage these technical approaches could not achieve the desired properties of very low electrical sheet resistance (EXCLUCENT™ achieved a sheet resistance lower than 0.1 Ohm/sq., which is tenfold lower than the best ITO coated substrates) and transparency better than 80% including the transparency of the substrate itself. Although metallic mesh based electrically conductive transparent substrates were introduced into the market using silver meshes, the EXCLUCENT™ product uses copper. ANI is currently developing methods to apply its copper ink product Cu-i70, a product that won a 2010 R&D 100 Award from R&D Magazine (see press release of July 9, 2010), to a variety of transparent substrates as a potential ITO coating replacement.
