UV-Absorption for Biological Application of (Polymer- Carbide) Nanocomposites

摘要

Bionanocomposites of polyvinyl alcohol (PVA) and tantalum carbide nanoparticles (TaC NPs) and studying their structural and optical properties for UV- radiation shielding applications. The prepared bionanocomposites have high absorbance for UV- radiation with low cost and low weight. The results showed that the optical parameters (absorbance (A), absorption coefficient (α) and optical conductivity (σ)) of biopolymer are increased with increase in tantalum carbide nanoparticles concentrations while the transmittance (T) and energy band gap (Eg) are decreased with increase in tantalum nanoparticles concentrations.
