Transparent mxene-polymer supercapacitive film deposited using rir-maple

Abstract

In this work, resonant infrared matrix-assisted pulsed laser evaporation (RIR-MAPLE), a novel deposition technique, was used to produce a transparent composite electrode of polyflourene (PFO) and two-dimensional (2D) Ti3C2Tx nanosheets, which are part of the broader MXene family of transition metal carbides and nitrides. This deposition technique offers a facile way to vary film composition in polymer/polymer and polymer/nanoparticle films. Through this method, composite PFO and MXene films were studied across six different compositions, enabling the identification of a film composition that exhibited excellent charge storage (above 10 mF/cm2) and transparency (over 75% transmittance) when used as a supercapacitor electrode material. Thus, RIR-MAPLE shows promise as a controllable and facile deposition technique for organic/inorganic composite films for use in transparent supercapacitors, as well as in other energy storage applications.
