Ionic Polymer-Based Removable and Charge-Dissipative Coatings for Space Electronic Applications

Protection of critical electronic systems in spacecraft and satellites is imperative for NASA's future missions to high-energy, outer-planet environments. The objective of this project is to develop flexible, transparent, and removable conformal coatings to protect delicate, mission-critical electronic components from electrostatic discharge damage. In collaboration with our partners, InnoSense LLC (ISL) proposes to develop a Transparent Conformal Conductive Coating that will meet the needs of NASA's space programs. The transparent conformal coatings will consist of a flexible and low-water-absorbing polymer matrix blended with conductive polymers. Phase I tasks focus on (1) preparing conductive polymers and conformal coating formulations, (2) developing coating and curing processes, and (3) testing conformal coatings with respect to adhesion, UV resistance, offgassing, resistivity, charge dissipation, ease of removal, and resistance to temperature cycling and vacuum.
