Conformal Electromagnetic Radiation Absorptive MXene-Integrated Composite (CERAMIC)

Physical Sciences Inc. (PSI) proposes to develop a novel ultra-thin and flexible electromagnetic interference (EMI) shielding material with high-temperature resistance for direct, conformal application to internal electronics of hypersonic craft. PSIÆs Conformal Electromagnetic Radiation Absorptive MXene-Integrated Composite (CERAMIC) coating incorporates MXene conductive filler material for high EMI shielding into PSIÆs own novel flexible SiC composite matrix using a pre-ceramic polymer (PCP) as a binder. This new technology will provide >48 dB of absorption-dominant EMI shielding, thereby preventing secondary EMI pollution and harmful effects on other internal systems, while remaining thin and flexible to meet low size, weight and power (SWaP) requirements. In this Phase I Small Business Innovation Research program, PSI will validate the feasibility of the CERAMIC coating technology by down-selecting to a final MXene/SiC/PCP composition that achieves the desired shielding properties in a thin film demonstrating high temperature resistance. In Phase II, we will further refine the CERAMIC coating prototype for optimal EMI shielding and thermal stability, implement formulation scale-up, and demonstrate fulfillment of the concept of operations (CONOPs) requirements through EMI testing of coated electronics packages.
