This thesis aims to develop a PVDF-based piezoelectric composite material with a cybersecurity model. The objectives include the synthesis of PVDF by incorporating HA, GO, and AgNO3 nanoparticles to create a piezoelectric composite characterized by β-phase transformation. The study also aims to evaluate the influence of HA, GO, and AgNO3 nanoparticles and their different compositions on the electrical, mechanical, and morphological properties of the piezoelectric composite. The study also aims to investigate the influence of GO on the piezoelectric, electrical, and morphological properties of the PVDF-based composite for sensing functional elements. The main focus is on the fabrication process of the functional element composed of PVDF, HA, GO, and AgNO3. The solvent casting method and the non-toxic solvent DMSO were chosen to fabricate the functional element. This fabrication method and materials were chosen to increase the beta phase, which is very important for data protection and piezoelectric properties. The results of the composites with PVDF, HA, GO, and AgNO3 are presented. The properties of materials are determined experimentally by measuring SEM, FTIR, vibration measurements, electrical characteristics, piezoelectric properties, hydrophilicity, roughness, and other characteristics. |
