摘要

The current work aims to fabricate futuristic nanocomposites films based on PVA/PVP polymer blend doped Al2O3/SiC NPs with different ratio to be utilized in different electronics applications. The morphological, optical and structural features of (PVA/PVP/Al2O3/SiC) nanocomposites films were examined. The morphological results showed the Al2O3/SiC NPs distributed inside the polymer blend matrix with good dispersion. FTIR spectra showed that creation of new interaction sites and modifies the polymer network without creating new chemical bands with the addition of Al2O3/SiC NPs The results reveal that the absorption of PVA/PVP increases to 93.75% at wavelength of 360 nm when the content of Al2O3/SiC NPs increases to 1.2 wt.%, the transmittance decreases of 43%. The energy gap reduce from 5.04 to 4.16 eV for allowed indirect transition and from 4.83to 3.54 eV for forbidden indirect transition with growing the contents of Al2O3/SiC NPs to 1.2 wt.%. the other optical parmeters were improved with increasing the contents of Al2O3/SiC NPs. Finally, These results making (PVA/PVP/ Al2O3/SiC) promising nanomaterials for advanced nanoelectronics applications.
