Self-assembled graphene@PANI nanoworm composites with enhanced supercapacitor performance

Synergetic effect of synthesized sulfonated polyaniline/quaternized graphene and its application as a high-performance supercapacitor electrode

“…5b). The strong p-p* conjugated system in nanohybrid demonstrates that the electron transfer facilitating between q-graphene and s-PANINa [44], and improving the electrochemical performance, which agreed well with the Raman analysis results, evidencing the outstanding conductivity of nanohybrid. Figure 6a compares the voltammograms of q-graphene, PANI and s-PANINa/q-graphene nanohybrid at the scan rate of 50 mV s -1 in the potential range of 0.0 to ?0.8 V in 1.0 M of H 2 SO 4 .…”

Synthesis and electrochemical investigation of polyaniline/unzipped carbon nanotube composites as electrode material in supercapacitors

“…PANI containing porous carbon materials with high surface area shows improved cycle life and specific capacitance as compared to pure PANI. PANI/Carbon nanofiber [18], PANI/CNT [19] and PANI/graphene [20,21] composites exhibit higher specific capacitance and better cycle life than pure PANI. Among all of the carbon nano-materials combined with PANI, graphene/CNT hybrid has been shown to be a promising electrode material for supercapacitors, which effectively improves electrochemical performance of the composite [22,23].…”

Porous nitrogen-doped graphene/carbon nanotubes composite with an enhanced supercapacitor performance

“…For the XPS spectrum of O 1s, two peaks are observed in Fig. 4c at 531.8 eV (C=O) and 533.2 eV (C-O-C/C-OH) [46]. A clear N 1s peak is observed in Fig.…”
