Adaptive Radiative Thermal Management with Solid-State Phase-Change Metamaterials

This research aims to advance radiative thermal management system by developing a solid-state phase-change metamaterial that can adaptively control the spectrum of emission and absorption of radiation. I will use my knowledge of metamaterials and nanofabrication to design and test an ultra-lightweight material layer capable of spectral selectivity and dynamic switching from heating to cooling. The key innovation in my approach is to adaptively control emissivity and reflectivity in the solar and thermal-IR spectrum, allowing for the metamaterial to outperform conventional reflective/emissive structures. This approach will provide several key advantages over current thermal regulation technology used in small satellites, including reducing mass and power consumption, incorporating spectral selectivity, and removing mechanical actuation. The proposed advanced material could increase the thermal efficiency of future satellites, spacecraft, and extraterrestrial habitats where temperature regulation is essential to human survival. By collaborating with NASA, I will be able to work alongside leaders in the development of space technology as well as contribute my knowledge to develop this promising concept into the next-generation thermal management system.

This is early/mid-stage (TRL 2) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
