    In this study, the blending electrospinning technique was successfully used to prepare poly (vinyl alcohol)/ethyl cellulose/tea polyphenol (PVA/EC-TP) nanofibrous films for the first time. The morphology observation showed that the fiber diameter ranged from 213 +/- 40 nm to 432 +/- 78 nm. The thermal analysis indicated that PVA/ECTP composite nanofibrous films had superior thermal stability to pure PVA nanofibrous film. The wettability test showed that the water contact angle of composite nanofibrous films was significantly increased from 22 degrees to 109 degrees. Water stability and water barrier ability analyses indicated the water solubility of composite nanofibrous films was significantly decreased from 100% to 17%, and the water vapor permeability was reduced from 0.71 to 0.42 g.mm/m2.h.kPa. Meanwhile, the PVA/EC-TP composite nanofibrous films exhibited good antioxidant and antimicrobial activity. The application assay showed that the PVA/EC-TP nanofibrous films with high TP content could effectively extend the shelf life of pork by 3 days.
