Abstract: The present disclosure provides a high heat radiation composite material including a hybrid filler comprising expanded graphite filled with expandable polymeric beads, and a fabrication method thereof. In the method, a dispersion solution is prepared by dispersing expandable polymeric beads in ethanol. Expanded graphite is immersed in the dispersion solution, and heat-treated to remove ethanol, thereby producing the hybrid filler. The hybrid filler is dispersed into the matrix polymer via an extrusion/injection process, thereby producing the composite material.

Abstract: Disclosed is a hybrid polymer composite for electromagnetic wave shielding, and a method for fabricating the same. Specifically, the hybrid polymer composite may be fabricated by combining a microcapsule that is surface coated with at least one carbon nanotube and includes a phase change material (PCM), whose phase easily transitions from solid to liquid upon exposure to heat, with at least one carbon fiber and a matrix polymer. The disclosed hybrid polymer composite has enhanced electromagnetic wave shielding properties that result, in part, from the ability of the PCM to dissipate and remove heat generated by electromagnetic absorption. Additionally, the disclosed composite has excellent conductivity due to its polymer properties and the formation of a network between fillers and the polymer.
