Electrically conducting polymers and composites for applications in space exploration

Abstract

Pushing the boundaries of space exploration and settlement requires innovative materials that are multi‐functional, reusable, and tolerant of the extreme hazards in space environments. Polymers represent an interesting class of materials for these applications due to their range of properties, low density, and ease of manufacturing. Electrically conductive materials based on polymers and other organic materials can be beneficial for safety purposes or for integrating advanced functions, such as dust mitigation and non‐destructive evaluation. Given the unique demands of the space industry, emerging materials developed for space may not appear in conventional forums. Conversely, many investigators focus on polymers and composites for other applications and may not realize the suitability of their material for space. This review provides an informational bridge between experts from conventional polymer fields and more space‐focused research groups. First, a brief history of polymer material integration from Apollo to Artemis is used as a context for their increasing importance to space exploration. Next, a polymer and composite materials‐focused summary of space hazards is discussed for different space environments. Finally, different space applications suitable for electrically conductive polymers and composites are discussed in the context of enabling space exploration and developing new terrestrial technology.
