Abstract

Ultrathin and flexible electromagnetic interference (EMI) shielding materials are required to deal with increasingly serious radiation pollution. Herein, 2D ultrathin Ti ₃ C ₂ T _x nanosheets, a kind of MXenes, possess metallic electrical conductivity and hydrophilic surfaces. 2D Ti ₃ C ₂ T _x are considered as a promising alternative to graphene for providing excellent EMI shielding properties. Flexible delaminated Ti ₃ C ₂ T _x /electrospun regenerate cellulose nanofibers (d-Ti ₃ C ₂ T _x /r-CNFs) composite films with EMI shielding properties were fabricated via a facile vacuum-assisted filtration method. The obtained d-Ti ₃ C ₂ T _x /r-CNFs composite film with 15 μm of the thickness of d-Ti ₃ C ₂ T _x coating shows excellent EMI SE (up to 42.7 dB) at the frequency of 2–18 GHz. The d-Ti ₃ C ₂ T _x /r-CNFs composite films can be potentially used as flexible EMI shielding materials.
