Abstract

Polycaprolactone/Zn(II) metal-organic framework composites (PCL/x%ZIF-8, x=10, 30, 50) were prepared by the simple solvent evaporation method. To investigate the structure of the obtained compounds infrared spectroscopy (FT-IR), powder X-ray diffraction (PXRD), scanning electron microscope (SEM), and EDS map analysis of zinc element were used. FT-IR spectra and XRD diffraction patterns confirmed the presence of ZIF-8 into the polymer matrix. SEM images showed the distribution of ZIF-8 nanoparticles in composite films. The as-prepared composites were more effective for adsorbing various oils (sunflower oil, olive oil, and motor oil) than the pure polymer film owing to the synergistic effect of polycaprolactone and ZIF-8 nanoparticles. The PCL/50%ZIF-8 composite exhibited the highest efficiency for motor oil adsorption (9.5 g g-1). Then, the antibacterial effect of these nanocomposites against E. coli bacteria was investigated. Furthermore, the results of antibacterial tests showed that PCL/50%ZIF-8 nanocomposite has a significant antibacterial effect against E. coli. As a result, these nanocomposites have the potential to be used in the field of removing some pollutants and thus water purification due to their strong antibacterial effect and hydrophobic properties.
