Technologies are needed to make these methods more reliable and standardized and increase the capability for effective ground testing. This area includes technologies that manage system heat primarily through the use of the thermal and/or optical properties of a given material. 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":2,"currentTrl":5,"endTrl":5,"benefits":"This technology may not only displace extant technologies for manned and unmanned space platforms and small as well as large spacecraft, as described under NASA applications above, but also give rise to much greater engineering design flexibility in space platforms as well as spacecraft. This may potentially open doors to profound new applications, e.g. in micro-satellites such as the CubeSats which currently have no thermal control means. This would \"democratize\" space, allowing small and medium businesses to launch their own, dedicated satellites. Other potential applications of this technology include terrestrial, military IR camouflage/stealth which this firm has been pursuing elsewhere, with an estimated market size about 3 X the space market, and building or shelter cover materials for desert climates with high night/day temperature variations, in both commercial and military applications.
This technology may displace extant, alternative technologies (e.g. those listed in the Abstract) on manned and unmanned space platforms, e.g. those originally planned under NASA's Constellation mission and now to be transitioned to new science missions, and small (micro-, 50%) portion for NASA.","description":"Variable-emittance materials are in high demand for applications ranging from manned and unmanned space platforms (e.g. in radiators at the Moon's poles where damage could be prevented during times of low heat load) to spacecraft thermal control (especially for micro-, nano-spacecraft where no effective thermal control currently exists). They are superior to technologies such as loop heat pipes, louvers, MEMS systems, electrostatic systems, phase change materials, and others. A key requirement is a high Turn-Down Ratio (TDR, ratio of high/low emittance), up to 10.0, and Delta-emittance, up to 0.55. In ongoing and recent prior work (for Air Force, JPL, NASA), this firm has developed a novel, patented variable emittance skin technology, based on conducting polymers (CPs), microporous membranes and ionic liquids, with proven, space-environment performance. The proposed work will develop this with further, radical innovations including entirely new CPs, to achieve a TDR of ca. 8.0 and possibly up to (from current ca. 3.0), and Delta-emittance of ca. 0.60 (from current ca. 0.50). The more than eight innovations are based on actual, prior experimental data and include incorporation of new CPs, alteration of the substrates and surfaces, radical increase in doping level, use of new ionic liquid electrolytes with higher conductivity and several others.","startYear":2011,"startMonth":2,"endYear":2011,"endMonth":8,"statusDescription":"Completed","principalInvestigators":[{"contactId":378337,"canUserEdit":false,"firstName":"Prasanna","lastName":"Chandrasekhar","fullName":"Prasanna Chandrasekhar","fullNameInverted":"Chandrasekhar, Prasanna","primaryEmail":"chandra.p2@ashwin-ushas.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":415205,"canUserEdit":false,"firstName":"Rubik","lastName":"Sheth","fullName":"Rubik B Sheth","fullNameInverted":"Sheth, Rubik B","middleInitial":"B","primaryEmail":"rubik.b.sheth@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":[],"transitions":[{"transitionId":68425,"projectId":9268,"transitionDate":"2011-08-01","path":"Closed Out","closeoutDocuments":[{"title":"Final Summary Chart","file":{"fileExtension":"pdf","fileId":307495,"fileName":"SBIR_2010_1_FSC_X3.04-8984","fileSize":139081,"objectId":68425,"objectType":{"lkuCodeId":1841,"code":"TRANSITION_FILES","description":"Transition Files","lkuCodeTypeId":182,"lkuCodeType":{"codeType":"OBJECT_TYPE","description":"Object Type"}},"fileSizeString":"135.8 KB"},"transitionId":68425,"fileId":307495}],"infoText":"Closed out","infoTextExtra":"","dateText":"August 2011"},{"transitionId":68424,"projectId":9268,"partner":"Other","transitionDate":"2012-04-01","path":"Advanced To","relatedProjectId":9580,"relatedProject":{"acronym":"","projectId":9580,"title":"High Turndown Ratio, High Delta-Emittance, Variable Emissivity Electrochromics","startTrl":6,"currentTrl":8,"endTrl":8,"benefits":"If successful, this variable-emittance technology may displace extant, alternative technologies (e.g. those listed in the Abstract) on manned and unmanned space platforms and spacecraft, including planetary and interplanetary platforms and small (micro-, 50%) portion for NASA. One example of an immediate future application is the Solar Probe Plus mission to Mercury, with expected launch in 2017-2018.
The commercial space industry, including future micro- and nano-spacecraft, near-space tourism, very high altitude balloons, large satellites, and possible future manned and unmanned space platforms, could all transition to this variable-emittance technology, displacing extant technologies.

This firm's unique, patented variable-emittance skin technology, based on conducting polymers, microporous membranes and ionic liquids, with proven, space-environment performance, remains at the world forefront, with highest known Delta-emittance, good Turn-Down Ratio (TDR), very low power, low cost. Phase I work demonstrated separate emittance variation from 0.065 to 0.816, Delta-emittance > 0.48, and long-term space durability, with one \"breakthrough\" innovation, two very significant innovations. A clear, specific pathway was demonstrated for combining low/high emittance in single devices to achieve TDR of 7.1, possibly 10.0. Phase II work will use this as basis to increase the TDR to > 7.1, possibly > 10.0, keeping the dark-state emittance ca. >/= 0.80. Surface Solar Absorptance will be further reduced from present ca. 0.31 to as low as possible (objective 0.09 to 0.24). Other Phase II tasks, following completion of TDR optimization, will address Controller, further space-qualification testing, manufacture, space-flights, commercialization pathway, other issues. Two identified commercial partners will assist in marketing.","startYear":2012,"startMonth":4,"endYear":2014,"endMonth":4,"statusDescription":"Completed","website":"","program":{"acronym":"SBIR/STTR","active":true,"description":"
