Abstract
In this study, graphene aerogels with high mechanical strength were successfully prepared by effectively doping graphene aerogels with different proportions of poly(vinyl alcohol) (PVA). The structure of the as-prepared aerogels was studied by means of field emission scanning electron microscopy (FESEM), Fourier-transform infrared (FTIR), Raman and X-ray photoelectron spectroscopy (XPS). The result indicated that the aerogels show a three-dimensional network-like structure and PVA has been successfully incorporated into graphene aerogels. The mechanical properties of the graphene aerogels doped with different proportions of PVA were tested, indicating that the PVA/GAs can support 7000 times of its own weight and its maximum compressive stress can be up to 400 KPa.
