2.4.2. UV-Visible Spectroscopy

The UV-visible spectroscopic study of the poly(o-anisidine)/BaSO4 nanocomposites was carried out using the Shimadzu double-bean spectrophotometer. The samples were prepared by dispersing 1 mg of the composite in 5 mL of distilled water. Then, the samples were scanned in the wavelength range of 200–800 nm.
