Synthesis and Evaluation of Nanocomposites Based on Random Polyesters Reinforced with Graphene Oxide Particles: Effects on Composite Properties
Year: 2025
Type: article
Abstract: This study investigates the impact of graphene oxide (GO) nanoparticles on the physical, chemical, and mechanical properties of random polyesters. The nanocomposites were synthesized using a step-growth polymerization technique, incorporating varying concentrations of GO (1%, 2%, and 3%). Mechanical tensile testing, thermal analysis, and X-ray diffraction (XRD) were performed to assess the performance of the prepared samples. The results revealed that a low concentration (1%) of GO significantly enhanced the mechanical properties and thermal stability of the polyester matrix, in addition to improving its crystalline structure. Conversely, higher concentrations (2% and 3%) led to nanoparticle agglomeration and a noticeable decline in both mechanical and thermal performance due to poor dispersion within the polymer matrix. These findings underscore the importance of optimizing filler content to improve composite properties and support their potential application in biomedical and electronic fields.
