Reshaping carbon-loaded epoximer composites with plasma for EMI shielding applications

We demonstrate carbon nanotube (CNT)-loaded vitrimers as reshapeable electromagnetic interference (EMI) shielding materials. In this work, CNTs serve dual roles as (1) susceptors enabling plasma-induced heating for reshaping and as (2) conductive fillers for EMI shielding. Results show that the plasma does not degrade the material surfaces and offers a convenient non-contact method to heat the materials and conform them to complex shapes. The films exhibit stable shielding effectiveness across the X-band, retain performance after multiple reshaping cycles, and offer a lightweight, versatile alternative to conventional rigid EMI shields. This work demonstrates a new strategy for integrating reconfigurability with EMI protection, expanding applications in aerospace, communications, and flexible electronics.
