This area includes in-space and ground applications.","exampleTechnologies":"Radiators, radiator turn-down devices (e.g. louvers, heat switches, variable conductance heat pipes), phase change materials, transpiration cooling, heat sinks, optical coatings, variable coatings, sunshades, molten salts, cryogens, evaporation, boiling, condensation, autonomous radiator maintenance, dust tolerant radiators, high heat load 500 - 500 kW rejection","hasChildren":false,"hasInteriorContent":true}],"startTrl":3,"currentTrl":6,"endTrl":6,"benefits":"The film will be applied to the exterior of NASA spacecraft or to electronics modules to regulate temperature.
Commercial versions of the material will help architects design energy efficient buildings by controlling infrared radiation.","description":"NASA missions, from earth orbit CubeSats to deep space, require thermal management. For this a switchable emissivity surface is desired, but the only established solution, mechanical louvers, is heavy and clumsy. In Phase I, Triton Systems working with materials scientists at a leading research university demonstrated an innovative film which switches from low to high emissivity above a set threshold temperature. Feasibility experiments showed the film self-switched from a low emissivity 0.08 to a high peak emissivity 0.97 above a critical temperature which can be engineered in the range 10-70C as required for a specific application. The film has no moving parts, is composed of all solid state, stable materials, can be deposited on flexible polyimide substrates, requires no external power or control, and shows no sign of deterioration or fatigue over millions of temperature change cycles. nmental tests will be carried out.","startYear":2015,"startMonth":5,"endYear":2017,"endMonth":8,"statusDescription":"Completed","principalInvestigators":[{"contactId":283750,"canUserEdit":false,"firstName":"Larry","lastName":"Domash","fullName":"Larry Domash","fullNameInverted":"Domash, Larry","primaryEmail":"Ldomash@Tritonsystems.Com","publicEmail":true,"nacontact":false}],"programDirectors":[{"contactId":206378,"canUserEdit":false,"firstName":"Jason","lastName":"Kessler","fullName":"Jason L Kessler","fullNameInverted":"Kessler, Jason L","middleInitial":"L","primaryEmail":"jason.l.kessler@nasa.gov","publicEmail":true,"nacontact":false}],"programExecutives":[{"contactId":215154,"canUserEdit":false,"firstName":"Jennifer","lastName":"Gustetic","fullName":"Jennifer L Gustetic","fullNameInverted":"Gustetic, Jennifer L","middleInitial":"L","primaryEmail":"jennifer.l.gustetic@nasa.gov","publicEmail":true,"nacontact":false}],"programManagers":[{"contactId":62051,"canUserEdit":false,"firstName":"Carlos","lastName":"Torrez","fullName":"Carlos Torrez","fullNameInverted":"Torrez, Carlos","primaryEmail":"carlos.torrez@nasa.gov","publicEmail":true,"nacontact":false}],"projectManagers":[{"contactId":3164318,"canUserEdit":false,"firstName":"Mark","lastName":"Hasegawa","fullName":"Mark Hasegawa","fullNameInverted":"Hasegawa, Mark","primaryEmail":"Mark.M.Hasegawa@nasa.gov","publicEmail":true,"nacontact":false},{"contactId":461333,"canUserEdit":false,"firstName":"Theresa","lastName":"Stanley","fullName":"Theresa M Stanley","fullNameInverted":"Stanley, Theresa M","middleInitial":"M","primaryEmail":"theresa.m.stanley@nasa.gov","publicEmail":true,"nacontact":false}],"website":"","libraryItems":[{"file":{"fileExtension":"pdf","fileId":296827,"fileName":"briefchart","fileSize":69014,"objectId":293358,"objectType":{"lkuCodeId":889,"code":"LIBRARY_ITEMS","description":"Library Items","lkuCodeTypeId":182,"lkuCodeType":{"codeType":"OBJECT_TYPE","description":"Object Type"}},"objectTypeId":889,"fileSizeString":"67.4 KB"},"files":[{"fileExtension":"pdf","fileId":296827,"fileName":"briefchart","fileSize":69014,"objectId":293358,"objectType":{"lkuCodeId":889,"code":"LIBRARY_ITEMS","description":"Library Items","lkuCodeTypeId":182,"lkuCodeType":{"codeType":"OBJECT_TYPE","description":"Object Type"}},"objectTypeId":889,"fileSizeString":"67.4 KB"}],"id":293358,"title":"Briefing Chart","description":"Spacecraft Thermal Control System Not Requiring Power, Phase II Briefing Chart","libraryItemTypeId":1222,"projectId":33282,"primary":false,"publishedDateString":"","contentType":{"lkuCodeId":1222,"code":"DOCUMENT","description":"Document","lkuCodeTypeId":341,"lkuCodeType":{"codeType":"LIBRARY_ITEM_TYPE","description":"Library Item Type"}}},{"caption":"Spacecraft Thermal Control System Not Requiring Power Briefing Chart","file":{"fileExtension":"jpg","fileId":299712,"fileName":"SBIR_2014_2_BC_S3.07-8767","fileSize":50470,"objectId":296250,"objectType":{"lkuCodeId":889,"code":"LIBRARY_ITEMS","description":"Library Items","lkuCodeTypeId":182,"lkuCodeType":{"codeType":"OBJECT_TYPE","description":"Object Type"}},"objectTypeId":889,"fileSizeString":"49.3 KB"},"files":[{"fileExtension":"jpg","fileId":299712,"fileName":"SBIR_2014_2_BC_S3.07-8767","fileSize":50470,"objectId":296250,"objectType":{"lkuCodeId":889,"code":"LIBRARY_ITEMS","description":"Library Items","lkuCodeTypeId":182,"lkuCodeType":{"codeType":"OBJECT_TYPE","description":"Object Type"}},"objectTypeId":889,"fileSizeString":"49.3 KB"}],"id":296250,"title":"Briefing Chart Image","description":"Spacecraft Thermal Control System Not Requiring Power Briefing Chart","libraryItemTypeId":1095,"projectId":33282,"primary":false,"publishedDateString":"","contentType":{"lkuCodeId":1095,"code":"IMAGE","description":"Image","lkuCodeTypeId":341,"lkuCodeType":{"codeType":"LIBRARY_ITEM_TYPE","description":"Library Item Type"}}}],"transitions":[{"transitionId":64296,"projectId":33282,"partner":"Other","transitionDate":"2015-05-01","path":"Advanced From","relatedProjectId":17807,"relatedProject":{"acronym":"","projectId":17807,"title":"Spacecraft Thermal Control System Not Requiring Power","startTrl":3,"currentTrl":4,"endTrl":4,"benefits":"NASA space platforms, from low earth orbit to deep space, all require thermal control. The Triton film technology is conformal and easily retrofitted to curved surfaces. Different film parameters including emittance spectrum and transition temperature can be designed for different missions, or even different surfaces on the same spacecraft. No external power is required. The film is very light in weight.
Defense applications of emittance control films include thermal signature modification for ships, aircraft, UAVs and land vehicles. Commercial applications are for thermophotovoltaics, or architectural energy control for roofs, windows and walls.","description":"The thermal management of spacecraft would be enhanced by dynamic control over surface emissivity in the mid-infrared. In this SBIR program, Triton Systems proposes to demonstrate a flexible film material whose emissivity self-switches from a low value to a high value when the film temperature exceeds a preset value. The wavelength of peak emissivity can be engineered between 1.5 to 15 ?m as desired, and the transition temperature can be varied between 5-70 C. The film is easily engineered for different requirements, and if desired, different film characteristics could even be applied to different areas of the same spacecraft. No external power is required. The film substrate is a light weight flexible material that can be produced in large areas by roll-to-roll nanoimprinting. Triton Systems has substantial background in the computational design and fabrication of these types of switchable emissivity materials. In addition to NASA applications, the material will serve military needs such as IR signature control for ships, aircraft, UAVs or land vehicles, commercial needs in thermo-photovoltaics, and for energy efficiency in residential and commercial architectural uses for walls, roofs and windows.","startYear":2014,"startMonth":6,"endYear":2014,"endMonth":12,"statusDescription":"Completed","website":"","program":{"acronym":"SBIR/STTR","active":true,"description":"
