Nanofiber Membranes

Blend films based on polyvinyl alcohol/polyethylene oxide (70/30 wt%) undoped and doped with different concentration of graphene oxide were prepared by spiral vane electrospinning. Characteristic properties of the blend films were investigated by using X-ray diffraction and scanning electron microscopy. The sound absorption performance of the compositions (nanofiber membranes and needle punched non-woven fabric) was tested by an impedance tube. The sound absorption performance of non-woven fabric has greatly improved after combining with thin nanofiber membranes. With addition of graphene oxide, the fibers were intertwined in a loop and form a network, the areal density and surface roughness of the nanofiber membrane are reduced. Composites containing polyvinyl alcohol/polyethylene oxide nanofiber membranes and composites containing polyvinyl alcohol/polyethylene oxide/graphene oxide nanofiber membranes exhibited different sound absorption properties in different frequency bands. When the fiber coefficient of variation was small, the average sound absorption coefficient of the composite material was high. However, composites containing both polyvinyl alcohol/polyethylene oxide and polyvinyl alcohol/polyethylene oxide/graphene oxide nanofiber membranes had similar sound absorption properties, and the average sound absorption coefficient was greater than that of polyvinyl alcohol/polyethylene oxide composites.
