Electrospun ZnO-based nanofibre membranes doped with AlCl₃ and CoAc were successfully fabricated for piezoelectric nanogenerator applications. The PVA precursor solution was prepared by dissolving PVA in distilled water and then processed using an electrospinning machine for 10 hours. Characterisation of the nanofibres was performed using scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD), and Fourier Transform Infrared Spectroscopy (FTIR) to examine the fibre and membrane properties. The SEM analysis revealed that the incorporation of Al and Co influenced the fibre morphology and size. The EDX confirmed the presence of Al and Co in the nanofibre membranes. The XRD results indicated that all the membranes exhibited an amorphous structure, while the FTIR analysis confirmed the complete evaporation of the solvent during the spinning process. The presence of a metal-oxygen phase plays a crucial role in analysing the crystal structure and piezoelectric characteristics of the material. |
