摘要
The multi-functionalization of polymer composites refers to the ability to connect multiple properties through simple structural design and simultaneously achieve multi-performance optimization.The large-scale design and mass production to realize the reasonable structure design of multifunctional polymer composites are urgently remaining challenges.Herein,the multifunctional MXene/graphene/polymer composites with three-dimensional thermally and electrically conductive network structures are fabricated via the utilization of the microstructure of the soft template,and a facile dispersion dip-coating approach.As a result,the polymer composites have a multiperformance improvement.At the MXene and graphene content of 18.7 wt%,the superior throughplane thermal conductivity of polymer composite is 2.44 W m^(−1)K^(−1),which is 1118%higher than that of the polymer matrix.The electromagnetic interference(EMI)shielding effectiveness of the sample reaches 43.3 dB in the range of X-band.And the mechanical property of the sample has advanced 4 times compared with the polymer matrix.The excellent EMI shielding and thermal management performance,along with the effortless and easy-to-scalable producing techniques,imply promising perspectives of the polymer composites in the next-generation smart electronic devices.
