Owing to the increase of electromagnetic pollution issues arising from the fast-growing development and need for electronic devices, the demand for lightweight materials with high electromagnetic interference shielding performance has become more urgent. Recently, MXenes, Ti3C2Tx, as conductive 2D nanomaterials have been considered for potential EMI shielding materials. We herein demonstrate a simple dip-coating approach for fabricating MXene dip-coated cellulose papers and cotton fabrics with high EMI shielding performance. For the purpose, substrates were repeatedly immersed into dispersion of MXene. The morphological and microstructural features of all samples were characterized by using SEM, EDS, and XRD. The electrical conductivity and EMI shielding performance were evaluated by using a resistance meter and network analyzer, respectively. The EMI shielding mechanism and effectiveness of all samples were analyzed by considering the microstructure and dip-coating cycle number. |
