Abstract Recycled polyethylene terephthalate (RPET) was doped with Neodymium Oxide (Nd 2 O 3 : 0, 1, 2, 4, and 8 wt.%) to investigate its structural, optical, dielectric, mechanical properties. X-ray diffraction (XRD) analysis revealed that pure RPET exhibited an amorphous structure, while the incorporation ofNd induced formation of crystalline phases, crystallinity increasing as Nd concentration increased. Fourier-transform infrared (FTIR) spectroscopy identified chemical interactions between , evidenced by a new band around 535 cm −1 . Optical using diffuse reflectance UV–Vis showed reduction in gap from 3.75 eV for 2.25 8wt.% samples, indicating enhanced optical Dielectric studies doping significantly decreased dielectric constant RPET, contributing thermal stability constant. Furthermore, loss conductivity improved, observed across varying temperatures. Dynamic (DMA) adding wt.% reduced storage modulus 1.62 GPa approximately 0.26 at 35 °C, attributed structural softening. These improvements suggest -doped is suitable applications requiring conductive REPT, low modulus, stability, energy dissipation capabilities.
