Polyvinyl alcohol/cinnamon essential oil/�-cyclodextrin (PVA/CEO/�-CD) antimicrobial nanofibrous membrane was successfully fabricated by electrospinning. Scanning electron microscopy (SEM) was applied to observe the morphology of nanofiber and the results showed that electrospinning parameters have significant influence on its morphology, and the optimal electrospinning conditions were as follows: voltage 15 kV, flow rate 0.4 ml/h and distance 14 cm. Under which, the diameters of nanofibers obtained were around 50-600 nm. Thermogravimetric analysis (TGA) indicated the nanofibrous membrane's thermostability was enhanced remarkably due to the encapsulation of CEO into �-CD. The molecular interaction among PVA, CEO and �-CD was demonstrated by attenuated total reflectance-fouriertransform infrared (ATR-FTIR) spectroscopy analysis. The PVA/CEO/�-CD nanofibrous membrane exhibited excellent antimicrobial activity, and the inhibition rate against Escherichia coli and Staphylococcus aureus reached above 90% when its concentration was 4 mg/ml, indicating it is potential for the application in active food packaging.
