Abstract: This study investigates the fabrication of thermoplastic nanocomposites films to apply in many optoelectronics and photonics fields. Films of polymethyl methacrylate (PMMA) and polyethylene glycol (PEG) doped with SiC–MnO 2 nanoparticles were prepared using the casting method. The structural, morphological, optical and dielectric features of thermoplastic films were examined. The optical features results indicated the absorbance was enhanced of 91% at a wavelength of λ = 360 nm. The optical band gap was decreased from 3.49 eV to 2.8 eV. Furthermore, the optical conductivity was improved of 73% at λ = 320 nm with increasing nanoparticle content up to 0.9 wt%, this behavior is suitable for optoelectronic applications. Regarding the dielectric properties, the dielectric features were enhanced with increasing nanoparticle content up to 0.9 wt%. Finally, the obtained results showed the PMMA–PEG/SiC–MnO 2 films are promising thermoplastic nanocomposites to apply in various optoelectronics and photonics devices.
