In this study, nanofibers with different ratios of poly(vinyl alcohol) and chitosan incorporated with moxifloxacin hydrochloride (MH/PVA/CS) were fabricated through the blending electrospinning, and the morphological features were tested using scanning electron microscopy (SEM). Further characterization of the new nanofiber was accomplished by Thermogravimetric analysis (TG), X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR). Antibacterial activity of the MH-loaded nanofibers at different drug loading were tested and compared with the blank group. Experimental results show that the MH/PVA/CS nanofibers exhibited the good antibacterial properties against Staphylococcus aureus and Pseudomonas aeruginosa due to the MH incorporation. Compared with blank nanofibers, MH/PVA/CS nanofibers have significantly better antibacterial properties, and different proportions of PVA and CS have a certain effect on the antibacterial activity of nanofibers. The conclusions in this paper show that MH/PVA/CS composite nanofibers may have great potential in antibacterial materials.

Poly(vinyl alcohol)/carbon nanotube (CNT) composite nanofibers were processed by both conventional and needleless electrospinning method. The effect of the processing parameters on the possibility of manufacturing was investigated. The results were evaluated by surface tension and conductivity measurements. For the investigation of surface morphology scanning electron microscopy (SEM) was used. It was concluded that surface treatment of carbon nanotubes was necessary for needleless electrospinning. Lower surface tensions were better for this process but the effect of conductivity was not so significant.
