After ultrasonic dispersion of graphene oxide (GO) prepared by modified Hummers method and surface carboxylated multi-walled carbon nanotubes (f-MWCNT), L-ascorbic acid was added and the MWCNT/thermally annealed graphene aerogel (MWCNT/TAGA) was obtained by thermal annealing. Polyaniline/MWCNT/TAGA...
