Abstract Title: Potential roles of graphene composites and metamaterials in human space exploration
Abstract Body: Human exploration of the Moon requires strong light-weight materials with exceptionally high thermal and electrical conductivities. Polymer composites utilizing reduced graphite/graphene-oxide (rGO) have been developed as potential space-suit “laminates”. These coatings have 10 Ω/□ sheet resistances; sufficient to provide static discharge paths for dust mitigation. The graphene field-effect transistor platform has also been used to develop radiation-sensitive metamaterials. Using CVD graphene transfer, electron beam lithography, and various fabrication methods, two neutron-series prototypes detectors have been developed. Ultimately, these will be integrated into space-suit material and interfaced with helmet displays for real-time active dosimetry during extravehicular activity.
