Polycaprolactone/Zn(II) metal-organic framework composites (PCL/x%ZIF-8, x=10, 30, 50) were fabricated by a simple solvent evaporation method. The as-fabricated materials were characterized by FTIR (Fourier-transform infrared), XRD (X-ray diffraction), SEM (scanning electron microscope), and elemental EDS (energy-dispersive X-ray spectroscopy) mapping. The FT-IR and XRD results proved that the ZIF-8 nanoparticles were successfully incorporated into the PCL matrix. SEM images showed that ZIF-8 was dispersed and coated by PCL. The as-fabricated composite films showed higher oil sorption capacities than the pure PCL film for all the investigated oils (sunflower oil, olive oil, and motor oil) owing to the synergic effects of PCL and ZIF-8. The PCL/50%ZIF-8 composite exhibited the highest oil sorption capacity for motor oil (9.5 g/g). In addition, the PCL/x%ZIF-8 films exhibited antibacterial activity against Escherichia coli. The obtained results propose that application of these materials for water treatment is feasible owing to their hydrophobicity and antibacterial properties.
