New self-cleaning materials of polymer fibers decorated with a hybrid between nanosized zinc oxide and expanded graphite (EG) or fullerene (C-60) were obtained. The new materials were prepared by applying electrospinning in conjunction with electrospraying. Poly(L-lactide) (PLA) was selected as a biocompatible and (bio)degradable polymer carrier. PIA solution was electrospun in combination with electrospraying of a suspension that contained the ZnO/EG or ZnO/C-60 hybrid. Mats with different content of EG or C-60 were obtained. The new materials were characterized by scanning and transmission electron microscopy (SEM and TEM), energy dispersive X-ray spectroscopy (EDX), X-ray photoelectron spectroscopy (XPS), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC) and X-ray diffraction analysis (XRD). The photocatalytic activity of the materials was evaluated by using model dyes. The formation of a hybrid between ZnO and EG led to enhancement of the photocatalytic activity of the mats at ZnO/EG weight ratios of 90/10 and 85/15. Increase in the photocatalytic activity of the ZnO-containing mats was also achieved by the formation of a hybrid between ZnO and Cm at a fullerene content of 0.5 and 1.0 wt% in respect to ZnO weight. The new materials exhibited antibacterial activity as evidenced by the performed studies against Staphylococcus aureus. (C) 2015 Elsevier B.V. All rights reserved.
