Abstract: Provided are sensors comprising one or both of MXene-coated fibers and MXene-coated yarns. The MXene-coated yarns can be utilized for various types of smart textile applications where conductivity is required. These include but are not limited to sensors (e.g. pressure, strain, moisture, and temperature), supercapacitors, triboelectric generators, antennas, and electromagnetic interference (EMI) shielding textiles.

Abstract: In an aspect, the present disclosure provides a heat-treated transition metal carbonitride MXene film annealed at high temperatures and a polymer composite comprising the same. In another aspect, the present disclosure provides a method for producing a heat-treated transition metal carbonitride MXene film comprising: obtaining a MXene aqueous solution containing dispersed 2-dimensional (2D) MXenes through an acid etching process; filtering the obtained MXene aqueous solution through a vacuum filtration process to produce a free-standing film; and annealing the produced free-standing film at high temperatures to obtain a heat-treated transition metal carbonitride MXene film. In still another aspect, the present disclosure provides an electromagnetic interference (EMI) shielding method comprising: superposing a coating comprising a heat-treated transition metal carbonitride MXene film on at least one surface of an object in a contact or non-contact manner.
