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.

Abstract: A garment includes a supercapacitor and/or heated fabrics including a first conductive yarn knitted to as to form a current collector and a second conductive yarn knitted to as to form an electrode that is in electrical contact with the current collector. The conductive yarns are knitted into a predetermined supercapacitor design having respective electrodes that are not in electrical contact with each other. An electrolyte saturates at least the electrode material either before or after knitting, and an ionically permeable electronic separator allows the electrodes to be in close proximity to each other without being in electrical contact with each other. A heating element may also be formed by knitting at least one of the first and second conductive yarns into a linear resistor or by knitting an insulated conductive yarn into a sheet of fabric. Such a heating element is connected to the supercapacitor via a switch.
