With the rapid development of 5G technology and the trend of miniaturization and miniaturization of electronic devices, the electromagnetic wave pollution brought by the technology becomes a serious threat threatening human health and inherent performance of components. Therefore, designing and manufacturing a high performance electromagnetic interference (EMI) shielding material having a dominant high absorption mechanism is of great importance to solve this problem.
In order to reduce secondary electromagnetic radiation pollution caused by reflection of electromagnetic waves on the surface of a material, constructing a highly porous three-dimensional structure is a key strategy for relieving the problem of impedance mismatch between the material and air. In recent years, the biomass charcoal has excellent performance and environmental protection property, and is applied to electrocatalysts and CO 2 The method has wide application prospect in the fields of adsorbents, supercapacitors, electromagnetic wave absorbents and the like. Cellulose is one of the most abundant renewable biomass resources on earth, and is considered as an alternative candidate material for easily constructing a 'green' organic aerogel with a three-dimensional interconnected network structure due to most of its strong intramolecular and intermolecular hydrogen bonds.

SE of MCA/TPU composite material prepared in embodiments 1-3 of the invention under different MXene contents T As shown in fig. 1, as the MXene content increases, the shielding performance increases; FIGS. 2 and 3 are SE for composites of examples 1-3 at different MXene contents R 、SE A A graph of the absorption coefficient of electromagnetic waves, R of the reflection coefficient and T of the transmission coefficient, and a graph of the power coefficient>0.75, far greater than the reflection coefficient, indicating that the shielding mechanism of the composite material is mainly absorption and has extremely low reflection efficiency<2dB, which indicates that the MCA/TPU composite exhibits excellent electromagnetic shielding performance.
The action mechanism of the method is as follows: by using the MCA/TPU composite material with the three-dimensional network structure, when electromagnetic waves are incident, the electromagnetic waves are easily introduced into the material due to the excellent impedance matching between air and the surface of the material. The porous structure has dense cross-linked tubes and a large number of dihedral angles, and then, incident electromagnetic waves attenuate the incident waves by multiple reflection and scattering within the porous structure, thereby obtaining superior electromagnetic shielding performance.
In the process of the invention, a three-dimensional porous MCA/TPU composite is prepared. The unique design of the three-dimensional structure of the composite material enables electromagnetic waves to enter more easily, and incident waves are attenuated by multiple reflection and scattering in the porous structure, so that excellent electromagnetic shielding performance is obtained. Thermoplastic polyurethane elastomers are widely used in various practical applications because of their high toughness, light weight, aging resistance, and the like. When the mass fraction of MXene in the prepared composite material is 3 wt% of cellulose (namely the MXene-carbon aerogel/TPU composite material prepared in example 3), the electromagnetic shielding effectiveness is 84.0 dB. This provides a feasible scheme for manufacturing a high-absorption electromagnetic shielding material with certain mechanical properties and excellent electromagnetic shielding performance.
