Strength Analysis of Precipitation-Synthesized Calcite-Zincite Composite Nanoparticles

Abstract:

Nanoparticles have become widely utilized in various industries, such as electronics, environmental science, cosmetics, material science, and medical systems, due to their diverse applications. In dentistry, researchers have shown significant interest in exploring the potential of calcium carbonate (CaCO₃) and zinc oxide (ZnO) nanomaterials, primarily because of their biocompatibility. This article specifically focuses on the integration of zincate nanoparticles (NPs) into poly (methyl methacrylate) (PMMA) resin at different concentrations (0%, 0.15%, 0.25% and 0.35%). The aim is to assess the impact of introducing calcite-zincate NPs on the mechanical properties of PMMA and compare them to PMMA without NP reinforcement. The specimens are created using the open mold method, both with and without NPs, through the auto-polymerization process of PMMA. Subsequently, these specimens undergo mechanical testing, while SEM images are analyzed to gain microscopic insights. The evaluation and comparison are made based on tensile strength. The results clearly indicate that the specimens reinforced with calcite-zincate NPs outperform those without NP addition, displaying superior mechanical properties.
