Abstract
enables dynamic Ku-band MA modulation through insulator-to-metal transition, yielding a maximum tunable EAB range (ΔEAB) of 8.35 GHz. A dynamic poly(urethane urea) matrix enables the composite to achieve adhesive-free layer assembly through self-healing. Thus, this composite is promising for applications in 5G/6G telecommunications, multi-band radar and health-monitoring flexible devices.
