In this study, eco-friendly nanocomposite films were prepared by using chitosan (CHS), PVA, titanium oxide (TiO2) nanoparticles, and plasticizers (sorbitol (SO) and citric acid (CA)). The CHS based nanocomposite films was characterized by using X-ray diffraction (XRD), fourier transform IR spectrophotometry (FT-IR), and scanning electronic microscope (SEM). The results of the XRD and FT-IR analysis verified that TiO2 characteristic peaks existed in the prepared nanocomposite films. In addition, the intensity of TiO2 characteristic peaks increased with increase of TiO2 contents The physical properties such as tensile strength (TS), elongation at break (%E), swelling behavior (SB), and solubility (S) of prepared nanocomposite films were investigated. The results indicated that compared with films without added TiO2 nanoparticles, the mechanical properties and water resistance were enhanced up to 1.42-1.50 times by the addition of TiO2 nanoparticles. The photocatalytic degradability of the prepared films containing TiO2 nanoparticles was evaluated using bisphenol A (BPA) and methyl orange (MO) as photodegradation targets. |
