Advanced Durable Flexible Ultra Low Outgassing Thermal Control Coatings for NASA Science Missions, Phase I

Completed Technology Project

Project Introduction

Advanced Durable Flexible Ultra Low Outgassing Thermal Control Coatings for NASA Science Missions, Phase I
This Phase I program proposes to synthesize novel nanoengineered ultra low out gassing elastomers and formulate high temperature capable flexible thermal control coatings as well as adhesives based on the proposed chemistries that are stable in various space environments. We have envisioned nano-engineered clusters and the innovative synthesis of the poly carborane-polysiloxanes, to surpass the performance of the current state of the art and provide the formulations that are space environment stable and can provide radiation hardening and enhanced life long survivability for science mission hardware in space environments. We propose to investigate: (1) Synthesis of high molecular weight ultra low outgassing poly-carborane-siloxanes that are stable and demonstrate for temperatures ≥ 500C. (2) Use of nano-engineered clusters with appropriate cross linker chemistries for tailoring secondary emission properties while providing protection from the irradiation using electron donor compounds. This can help us to employ electron on demand strategy to mitigate the secondary and sustained arcs. (3) Investigations in to: thermal stability thermally induced out-gassing studies, ESD behavior, and space environment simulation of elastomers for the typical GEO and LEO scenarios. These results from this study will guide us to select the promising formulations for the scale up and validation studies in Phase II. Lastly, we have proposed investigations in Boron Nitride Self Assembled Nano Cluster Mesh (BN-SANCsTM), which may totally change the way we formulate the space stable thermal control material systems for all earth orbits and planetary environment, along with its use in radiation shielding with use of 10BN-SANCsTM.
