- Description
- Pacific Northwest National Laboratory (PNNL), operated by Battelle Memorial Institute under contract to the U.S. Department of Energy, solicits interest from companies interested in obtaining license rights to commercialize, manufacture and market the following technology. License rights may be issued on an exclusive or nonexclusive basis and may include specific fields of use. PNNL may also be available to licensee(s) to assist in further research and development of the technology under a sponsored research agreement or CRADA program. The Technology: This technology is a method for producing a titanium oxide-containing film on a substrate that involves preparing an aqueous solution of a titanium chelate and immersing a substrate in the aqueous solution for a time sufficient to produce an adherent titanium oxide film on the substrate surface. The coating increases the selectivity of membranes used in gas separations. It is also a means for depositing the films directly on to hydrophobic surfaces, such as polyethylene, to increase their resistance to ultraviolet damage. The process is believed to be particularly applicable to the coating of gas permeable membranes (to increase selectivity in separations) and plastic parts (to increase resistance to damage from ultraviolet light). After preparing an aqueous solution of a titanium chelate, a substrate is immersed in the solution until a titanium oxide film adheres to the substrate surface. The titanium chelate may be an acid or base, decomposed by temperature or other means. The immersion process produces uniform coverage and high adhesion of the coating to the substrate. The process is believed to be particularly applicable to the coating of gas permeable membranes (to increase selectivity in separations) and plastic parts (to increase resistance to damage from ultraviolet light). It is also a means for depositing the films directly on to hydrophobic surfaces, such as polyethylene, to increase their resistance to ultraviolet damage. The hard surface may also provide scratch resistant coatings for lenses and the like. Experimental tests have shown that this technique is extremely effective in reducing yellowing and other degradation of commercially available plastic parts exposed to light (e.g. light fixtures). Although industrial scale-up has not been investigated, it is believed to be fairly straightforward since this is an aqueous solution deposition technique. Other thin film preparation techniques, such as liquid methods often result in films of low density, whose microstructures are poorly controlled. Thin films produced by liquid solution methods also suffer shrinkage and cracking during drying, crystallization and sintering. Gas-phase methods require direct growth of materials by heterogeneous nucleation from the gas phase; requiring high temperatures at the source and a vacuum, thus increasing costs and limiting processing choices. Advantages: (1) Low cost easy to perform--Does not require high temperatures or vacuum; (2) Uniformly coats complex and irregular shapes. Potential Applications: (1) Protective layers for lenses. (2) Selective filters. Can be used to block uv, infrared, or microwave radiation. (3) Self-cleaning windows. (4) Selective gas-permeable films. (5) Semiconductors, magnetic films electrochemical sensors, or electro-optic devices. Please see US Patent No. 5,766,784. Note: THIS IS NOT A PROCUREMENT. Any company interested in licensing this technology must respond with a letter of interest (may be submitted by e-mail) no later than 30 days from the publication date of this Notice summarizing the company?s business and technical expertise and motivation for pursuing this opportunity. Companies deemed appropriate will be provided with further information on the technology. Such information may require an executed Nondisclosure Agreement. Respondents wishing to enter into negotiations for a commercial license will be required to submit a business plan for the commercialization of the technology prior to licensee(s) selection and negotiations. Please send letters of interest to the attention of the POC identified within this Notice.
