In this paper, a solution casting technique has been used to investigate the nanocomposite from polyvinylalcohol (PVA) and polyethylene glycol (PEG) with additive different (1.5, 3, and 4.5) wt.% of zirconium carbide nanoparticles (ZrC NPs). The absorption spectrum between 200 and 800 nm was examined using a UV-Vis spectrophotometer. The addition of ZrC nanoparticles to the polymeric system improves the absorption of ultraviolet waves. While transmittance ratios (85-70%) are maintained allowing it to be employed for a variety of purposes, including solar radiation shields, low-cost UV protection, and drug packaging. The optical energy gap for indirect transitions (allowed and forbidden) shrank as ZrC NP content increased. Also, every optical constant has been studied, The parameters that have been experimentally studied for the nanocomposite (PVA-PEG-ZrC) have shown results that are identical to the theoretical studies and the mathematical relationships that govern these parameters.
