Influence of the Addition of Nano Cerium Oxide/Chitosan Composite on the physical Characteristics of Polymethylmethacrylate Resin

الملخص

Cerium oxide and chitosan (Ce/CS) nanoparticles' antioxidant, biocompatible, antibacterial, and anti-inflammatory properties have garnered interest. Integration of a Ce/CS nanocomposite into polymethylmethacrylate (PMMA) resin affects its physical properties. Based on an initial investigation, the composite consisted of 30% cerium oxide and 70% chitosan by weight, blended with PMMA resin in varying proportions. Data analysis showed significant differences among all groups (P≤0.05). Surface roughness did not change between the control and experimental groups employing 1% and 5% CS/Ce (P > 0.05). Water sorption and solubility were lowest in group B compared to A and the control group. The FTIR graph showed changed chemical structure, suggesting new functional groups. Ce/CS nanocomposite was evenly distributed in group A's PMMA matrix by SEM compared to group B. The study found that adding 5 wt.% nano cerium oxide/chitosan composite to PMMA denture base resin reduces its water sorption and solubility. The surface roughness of PMMA resin improved non-significantly using 1 and 5 wt.% Ce/CS nanocomposites.
