Structures and Performances of PA6/PVA Nanofibers Membranes from Electrospinning

The effects of different proportions of poly (vinyl alcohol) and polyamide 6 on the structure and property of electrospun PA6/PVA membranes have been studied. According to a certain proportion, PVA and PA6 were dissolved in formic acid. The solution was electrospun at 70 kV. The nanofibers membranes were characterized by SEM, FT-IR, XRD, TGA and DSC analyses. The sound absorption coefficients of each absorber are measured with SW477 impedance tube. PA6/PVA composite mats with good compatibility and relatively stable performance, and enhanced sound absorption and property may have many other important applications.
