Polymers constitute an extremely large class of materials generally based on carbon chemistry. Their long chain structures and unique molecular architecture make them distinct from metals and ceramics and provide them with a very wide range of properties. Polymers are also easily modified by the addition of other materials (fillers) to provide an almost limitless range of possibilities. Polymeric materials are the basis for many spacecraft components such as adhesives, circuit boards, temperature regulating“blankets”, lubricants, coatings, electrical insulation, paints and high stiffness composites. As a class of materials, they continue to evolve, with further advances in both performance and applications. Current developments of micron thickness films may eventually become enabling for certain types of spacecraft (solar sails), which will be the cornerstone of future missions such as the challenging Inter-Stellar Probe (ISP).
