Application progress on polymer-based MXene photothermal composites
Transition metal carbon/nitride(MXene)is an newly developed two-dimensional nanomaterial with tunable composition,controllable structure,and excellent photothermal conversion properties.MXene provides a new way for effective utilization of solar energy due to its sunlight absorption and efficient photothermal conversion performance.Incorporation of MXene into polymer matrix leads to excellent photothermal properties as well as stability enhancement and has been widely investigated.Here,the preparation methods of MXene and polymer-based MXene photothermal composites were summarized,followed by introduction on their photothermal conversion mechanism.The application progress on polymer-based MXene photothermal composites in seawater desalination,personal thermal management,photothermal antibiosis,and photothermal therapy was further summarized.The future development directions of polymer-based MXene photothermal composites was discussed in response to the existing application challenges including the difficulty in green and safe production of MXene,the susceptibility to oxidization,and the poor dispersibility in the polymer matrix.
