Modern materials are increasingly expected to perform under extreme conditions, whether in bioprocessing systems on Earth or in space infrastructure. Xheme develops advanced polymer films enhanced with proprietary nano-additives designed to resist oxidative and radiation-driven degradation while remaining safe, durable, and commercially scalable.
Through a research program supported by the ISS National Laboratory, select Xheme film samples will be mounted externally on the International Space Station as part of the MISSE-22 mission. These materials will be directly exposed to the space environment for several months before being returned to Earth for analysis.
What Will Be Evaluated
- Resistance to radiation and ultraviolet exposure
- Protection against atomic oxygen–driven oxidative damage
- Structural and chemical stability after prolonged exposure
- Performance comparison before and after flight
Why This Matters
This mission enables Xheme to:
- Validate material performance under the most demanding real-world conditions
- Refine next-generation durable and sustainable polymer systems
- Extend applications across both terrestrial and space-based environments
More broadly, the work supports Xheme’s vision of a terrestrial–extraterrestrial innovation loop—where insights from space directly inform better materials design on Earth.
