A comparative study of PMMA/PEG polymer nanocomposites doped with different oxides nanoparticles for potential optoelectronic applications
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 hind...
