Abstract:

In order to improve the proton conductivity and dimensional stability of the Nafion proton exchange membrane, a well-designed structure is in high demand. A graphene oxide quantum dot (GOQDs) / polyacrylonitrile (PAN) nanofiber membrane was prepared by electrostatic spinning technology, and a nanofiber composite proton exchange membrane was prepared by Nafion solution impregnation method. The structures and properties of nanofibers and composite membranes were characterized by scanning electron microscope, confocal microscopy, thermal gravimetric analyzer and X-ray diffractometer. The results show that GOQDs are evenly distributed in PAN nanofibers, and the addition of GOQDs reduces the diameter of the nanofiber. The three-dimensional network structure of nanofibers plays a skeletal support role in the composite membrane, which improves the dimensional stability of the composite membrane. At the same time, the thermal stability and water absorption of the composite membrane is improved. With the increase of GOQDs mass fraction, the proton conductivity of the composite membrane is improved, and the maximum proton conductivity of the composite membrane reaches 0.182 S/cm at 80 ℃.
