TECHNOLOGY TRANSFER OPPORTUNITY -- Chemical and topographical surface modifications for insect adhesion mitigation on aluminum surfaces: LAR-18127-1

NASA Langley Research Center in Hampton, VA solicits inquiries 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. NASA provides no funding in conjunction with these potential licenses. THE TECHNOLOGY: Scientists at NASA Langley Research Center have developed a method to reduce insect adhesion on metallic substrates, polymeric materials, engineering plastics, and other surfaces. The method topographically modifies a surface using laser ablation patterning followed by chemical modification of the surface. This innovation was originally developed to enhance aircraft laminar flow by preventing insect residue buildup, but the method provides a permanent solution for any application requiring insect adhesion mitigation as well as adhesion prevention of other typical environmental contaminants. The technology is a method of mitigating insect residue adhesion to various surfaces upon insect impact. The process involves topographical modification of the surface using laser ablation patterning followed by chemical modification or particulate inclusion in a polymeric matrix. Laser ablation patterning is performed by a commercially available laser system and the chemical spray deposition is composed of nanometer sized silica particles with a hydrophobic solution (e.g. heptadecafluoro-1,1,2,2-tetrahydrodecyltriethoxysilane) in an aqueous ethanol solution. Both topographic and chemical modification of the substrate is necessary to achieve the desired performance. NASA is seeking to license this technology commercially. US Patent pending. To express interest in this opportunity, please respond to [email protected] with the title of this Technology Transfer Opportunity as listed in this FBO notice and your preferred contact information. Please also provide the nature of your interest in the technology along with a brief background of your company. For more information about licensing other NASA-developed technologies, please visit the NASA Technology Transfer Portal at http://technology.nasa.gov/ . These responses are provided to members of NASA Langley’s Office of Strategic Analysis and Business Development “OSACB” for the purpose of promoting public awareness of NASA-developed technology products, and conducting preliminary market research to determine public interest in and potential for future licensing opportunities. If direct licensing interest results from this posting, OSACB will follow the required formal licensing process of posting in the Federal Register. No follow-on procurement is expected to result from responses to this Notice.
