Ultrathin and flexible electromagnetic interference (EMI) shielding materials are required to deal with increasingly serious radiation pollution. Herein, 2D ultrathin Ti3C2Tx nanosheets, a kind of MXenes, possess metallic electrical conductivity and hydrophilic surfaces. 2D Ti3C2Tx are considered as a promising alternative to graphene for providing excellent EMI shielding properties. Flexible delaminated Ti3C2Tx/electrospun regenerate cellulose nanofibers (d-Ti3C2Tx/r-CNFs) composite films with EMI shielding properties were fabricated via a facile vacuum-assisted filtration method. The obtained dTi(3)C(2)T(x)/r-CNFs composite film with 15 mm of the thickness of d-Ti3C2Tx coating shows excellent EMI SE (up to 42.7 dB) at the frequency of 2-18 GHz. The d-Ti3C2Tx/r-CNFs composite films can be potentially used as flexible EMI shielding materials. (c) 2019 Elsevier B.V. All rights reserved.
