Towards a new era of 2D materials-based multifunctional composites film: From innovation to evolution

Novel 2D materials are now at the forefront of developing advanced multifunctional composite film due to their fascinating properties. Particularly, graphene and MXene-based 2D materials are regarded as potential multifunctional materials for structure–function and integration with laminated composites. As expected, high mass production from low-cost and facile fabrication techniques for multifunctional composites film plays a pivotal role in their practical applications. Herein, we have covered a broad spectrum of 2D materials overview, covering all contributions to this field and summarizing the most pertinent literature available for developing multifunctional composites which are attractive for advanced aircraft applications. Moreover, the integrated functions of the 2D materials-based multifunctional composites such as sensing and actuation behaviour, thermal conductivity, and electromagnetic interference (EMI) shielding effectiveness are explored and their mechanism for superior performance is detailed. Some prevailing challenges with perspectives of this thriving field have also been critically discussed.
