Abstract

The water stability of electrospun poly(vinyl alcohol) (PVA) nanofibres was improved significantly by annealing with poly(acrylic acid) (PAA). Effects of annealing were tested on solution-cast PVA/PAA films by measurement of the swelling degree. The influence of PVA/PAA ratio, annealing temperature and period, molecular weight of PAA, and addition of esterification catalyst was investigated. The results were verified by a significant improvement of the water-stability of electrospun PVA/PAA composite nanofibres.
