Designing multifunctional material with high thermal conductivity and outstanding EMI shielding effectiveness is important to solve integrated electronics overheating and electromagnetic interference. Herein, we reported a scalable fabrication method for making nanocomposites with tunable thermal conductivity and high EMI shielding performance. The poly(methyl methacrylate) PMMA beads were coated with a hybrid shell of MXene (MX) and reduced graphene oxide (rGO) via electrostatic interaction and employed to construct a 3D structure of MXene/rGO in PMMA composites (MXrGO@PMMA) under hot-compression. MXrGO@PMMA composites with only 2 vol% total fillers possessed tunable thermal conductivity and EMI SE in the range of 0.98 to 3.96 W/mK and 28 to 61 dB, respectively, while varying the volume fraction of MXene and rGO. The research was supported by a grant from the Academic Research Program of Korea National University of Transportation in 2022. Composites Part A 149 106574 (2021).
