Abstract
- Here, Ni@graphene nanoplatelet (GNP) nanohybrids are obtained via an interfacial reaction growth method and a series of poly(methyl methacrylate) (PMMA)/Ni@GNP composites are prepared by a solution mixing‐ultrasonic dispersion‐hot pressing technology. The influence of Ni@GNP on the electromagnetic interference (EMI) shielding, dielectric, and thermal management behaviors of the composites is intensively investigated. The microcapacitors formed using Ni@GNP as plates and PMMA as matrix significantly improve the dielectric properties of the composites. Enhancement on thermal conduction and EMI properties of PMMA composites with increasing Ni@GNP content can be ascribed to the unique structure of Ni@GNP and it is the filler interconnection network that renders the composite's desirable thermally conductive and thermomechanical properties. A facile way of fabricating polymeric composites with satisfactory thermal conductivity and high‐performance electromagnetic shielding is provided here. The obtained polymer composites display highly promising applications in the thermal management and EMI shielding of electronic devices. [ABSTRACT FROM AUTHOR]
