In this study, nanocomposite films were prepared by using mungbean starch(MBS), PVA, zinc sulfide (ZnS) nanoparticles, and plasticizers (glycerol (GL), citric acid (CA), ascorbic acid (AsA), and dopamine (DPM)). ZnS was synthesized by the reaction of Zn(CH3COO)2 and Na2S2O3·5H2O in aqueous solution via a template-free hydrothermal process. The ZnS and MBS/PVA 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 ZnS characteristic peaks existed in the prepared nanocomposite films. 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 ZnS nanoparticles, the mechanical properties and water resistance were enhanced up to 1.30-1.45 times by the addition of ZnS nanoparticles. The photocatalytic degradability of the prepared films containing ZnS nanoparticles was evaluated using bisphenol A (BPA) and methyl orange (MO) as photodegradation targets. |
