Abstract

In this work, the PbZr_0.52Ti_0.48O₃ (PZT) nanocrystalline particles were effectively produced using the sol–gel method and then integrated into polycarbonate (PC) to create composites with various PZT concentrations. The produced PZT particles, PC, and PC/PZT composites were evaluated using X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), ultraviolet–visible spectroscopy (UV–Vis), and scanning electron microscopy (SEM) techniques. XRD and FTIR investigations verified the development of perovskite PZT nanoparticles free of the pyrochlore phase at 700 °C, with a tetragonal structure and an average crystallite size of PZT nanoparticle is about 56 nm. The XRD pattern revealed its amorphous structure, while the FTIR spectra indicated the presence of CH, CO, CC, and CO bonds. FTIR spectra showed metal-oxide bonds between 400–800 cm⁻¹, while UV–Vis examination revealed a band gap energy of 2.7 eV. SEM images revealed aggregation among spherical PZT particles. SEM images revealed strong adherence and aggregation of PZT particles within the polymer matrix. The dielectric characteristics of the PC/PZT composites improved with increasing PZT concentrations. The improved interfacial mechanism in ceramic-polymer composites can be used to obtain high dielectric constants.

期刊介绍： The journal offers a common reference and publication source for workers engaged in research on the experimental and theoretical aspects of crystal growth and its applications, e.g. in devices. Experimental and theoretical contributions are published in the following fields: theory of nucleation and growth, molecular kinetics and transport phenomena, crystallization in viscous media such as polymers and glasses; crystal growth of metals, minerals, semiconductors, superconductors, magnetics, inorganic, organic and biological substances in bulk or as thin films; molecular beam epitaxy, chemical vapor deposition, growth of III-V and II-VI and other semiconductors; characterization of single crystals by physical and chemical methods; apparatus, instrumentation and techniques for crystal growth, and purification methods; multilayer heterostructures and their characterisation with an emphasis on crystal growth and epitaxial aspects of electronic materials. A special feature of the journal is the periodic inclusion of proceedings of symposia and conferences on relevant aspects of crystal growth.
