    • Abstract:
      This study investigates the impact of oleic acid on the dynamic viscoelastic behavior of polymethyl methacrylate (PMMA) polymer films. By incorporating oleic acid as a plasticizer, we aim to enhance the ductility and reduce the brittleness of PMMA. Dynamic mechanical analysis (DMA) was employed to assess changes in viscoelastic properties, revealing significant improvements in the flexibility and energy dissipation capacity of the PMMA films. The addition of oleic acid resulted in a noticeable shift in the glass transition temperature and a reduction in storage modulus, indicating enhanced polymer chain mobility. Raman and infrared spectroscopy confirmed the successful integration of oleic acid, highlighting its interaction with PMMA at the molecular level. Our findings demonstrate that oleic acid is an effective plasticizer for PMMA, providing valuable insights into the design of flexible and durable polymer-based materials for various applications.
