In missions requiring stringent thermal control however high thermal insulation may be necessary, for example in hot environments and/or for cold instrument detectors like on ATHENA, infra-red observatories (L5), or cosmic microwave background mission (L6). But electrical conductivity and thermal insulation are typically mutually exclusive, because the high mobility of electrons in electric conductors allows those electrons also to increase their temperature and thus transport heat when moving in the electrical current flow.Functional materials like structured composites or meta-materials with engineered material properties could combine these usually exclusive properties. As a first step, candidate materials need to be identified and prescreened for space applications. To serve as efficient electrical grounding path, the electrical conductivity is important over a wide frequency range.This activity encompasses the following tasks:- Review existing functional materials like structured composites and metamaterials regarding electrical conductivity and thermal insulation properties- Design a group of 5 functional materials which maximize electrical and minimize thermal conductivity - Implement and manufacture 10 samples of 2 designed materials- Characterize o their effective electrical conductivity (both real and imaginary part, to limit reactive contributions like inductive or capacitive), and o thermal insulation, also regarding relation with applied voltage and current AC current frequency , and temperatures.Read more Directorate Directorate of Tech, Eng.
