‚ÄčABSTRACT: This thesis demonstrates the utilization of MXene-derived materials, e.g. ferroelectric crystals and nanocomposites, in opto-electronics applications. We have successfully synthesized two-dimensional Nb2C MXene based high aspect ratio ferroelectric potassium niobate (KNbO3) and well-oriented photoluminescent rare earth doped lithium niobate (LiNbO3:Pr3+) crystals. Furthermore, we demonstrate that poly(vinylidene fluoride) (PVDF)-based percolative composites using two-dimensional (2D) MXene nanosheets as fillers exhibit significantly enhanced dielectric permittivity. In addition, the strong effect of MXene flake size and surface terminals on the dielectric permittivity enhancement in MXene polymer composites and the potential of MXene/P(VDF-TrFE-CFE) composites as solid-state electrostatic fractional capacitors were also discussed. Furthermore, we fabricated MXene/3D aligned PVDF photo-thermo-mechanical actuator for solar tracking application.
