A double crosslinking MXene/cellulose nanofiber layered film for improving mechanical properties and stable electromagnetic interference shielding performance
文献摘要：
With the discovery of the two-dimensional(2D)MXene,it shows a great application potential in the field of electromagnetic interference(EMI)shielding,but the mechanical brittleness and easy oxidation of MXene limit its wide application.For this reason,a double crosslinking strategy is provided to solve the above problems in a nacre-like"brick-mortar"layered MXene/cellulose nanofiber(MXene/CNF)film.Typically,the film was firstly suffered by dopamine modification,then was further reinforced by sec-ondary Ca2+bridging,so as to obtain excellent mechanical properties and antioxidative EMI shielding performance.Comparing with the single crosslinking,the double crosslinking strategy reveals a higher efficiency in improving the mechanical property.The mechanical strength and toughness of the dou-ble crosslinking MXene/CNF film can increase to 142.2 MPa and 9.48 MJ/m3,respectively.More impor-tantly,while achieving good mechanical properties,the MXene composite film still holds a very stable EMI shielding performance of more than 44.6 dB when suffering from the oxidation treatment of high-temperature annealing,showing excellent anti-oxidation ability and environment tolerance.Therefore,this work provides a universal but effective double crosslinking strategy to solve the mechanical brit-tleness and easy oxidation of MXene-based composites,thus showing a huge potential in flexible EMI shielding applications.
