Optical properties of MXene-based hybrid nanocomposites

Abstract

Ti₃C₂T_x MXene/PANI (polyaniline), Ti₃C₂T_x MXene0.19/PbO and MXene0.03/PbO0.86/ PANI0.11 nanocomposites were synthesized by in situ polymerisation with lead(II)oxide (PbO) nanoparticles produced via hydrothermal route. The fundamental scientific and future development trends and research directions of MXene-based organic and inorganic nanocomposites in the field of optical functional materials are anticipated.  The structural and optical properties of Ti₃C₂Tₓ MXene0.19/PbO and MXene0.03/PbO0.86/PANI0.11 nanocomposites were examined, including absorbance (A), reflectance (R), optical band gap (Eop), Urbach energy (Eᵤ), refractive index (n), the real part of the complex dielectric permittivity (ε′) and optical conductivity (σ′). The absorbance spectra revealed maximum absorption peaks at 636 nm for Ti₃C₂Tₓ MXene0.19/PbO and 332 nm for MXene0.03/PbO0.86/ PANI0.11.
