Abstract
The aim of this study was to investigate the cross-linked poly(vinyl alcohol)
nanofibrous mats treated by flourinated alkane in supercritical carbon
dioxide medium. The surface morphology and chemical structure of electrospun
mats were analyzed by scanning electron microscopy and Fourier transform
infrared. The results showed that the treated mats could maintain their
integrity and fibrous morphology as well as their porous structure after
being treated. However, the wettability was changed greatly, the average
contact angle of treated nanofibrous mats increased from its original value
of 28? to 134?, revealing that the treated mats had good water repellent
properties. The paper concluded that the hydrophobic and breathable mats with
porous structure might be an excellent candidate for food package materials.
