Abstrakt: PMMA/PEG and PMMA/PEG doped with SiO 2 , TiO 2, and Al 2 O 3 were fabricated using the solution-casting technique. The composites were characterized by X-ray diffraction and scanning electron microscopy (FE-SEM), which revealed that the amorphous nature of PMMA/PEG blend doped with Al 2 O 3 was hindered by the crystalline nature of those doped with SiO 2 and TiO 2 . The absorption of PMMA/PEG blend doped with Al 2 O 3 is higher, band gap energies were decreased from 4.90 eV for PMMA/PEG blend to 4.03 eV, 3.09 eV, and 2.09 eV for SiO 2 , TiO 2 , and Al 2 O 3 doped PMMA/PEG blend, respectively. The dielectric constant, ε' has a high value (2 × 10 4 ) for samples PMMA/PEG and SiO 2 /PMMA/PEG. While dielectric loss ε ″ -values decreased to < 100 for TiO 2 /PMMA/PEG and Al 2 O 3 /PMMA/PEG. Further, the fabricated composite SiO 2 /PMMA/PEG led to improvement the optical and dielectric properties compared with PMMA/PEG for optoelectronic such as manufacturing of optical fiber cables application. The results show TiO 2 /PMMA/PEG and Al 2 O 3 /PMMA/PEG are multifunctional can be used as low-permittivity nanodielectric and substrates to design the next generation of flexible electronic devices.
