Composites Based on Poly(ortho-toluidine) and WS<sub>2</sub> Sheets for Applications in the Supercapacitor Field
In this work, three methods for the synthesis of composites based on poly(ortho-toluidine) (POT) and WS<sub>2</sub> are reported: (a) the solid-state interaction (SSI) of POT with WS<sub>2</sub> nanoparticles (NPs); (b) the in situ chemical polymerization (ICP) of ortho-tolui...

| description | In this work, three methods for the synthesis of composites based on poly(ortho-toluidine) (POT) and WS<sub>2</sub> are reported: (a) the solid-state interaction (SSI) of POT with WS<sub>2</sub> nanoparticles (NPs); (b) the in situ chemical polymerization (ICP) of ortho-toluidine (OT); and (c) the electrochemical polymerization (ECP) of OT. The preparation of WS<sub>2</sub> sheets was performed by the ball milling of the WS<sub>2</sub> NPs followed by ultrasonication in the solvent N,N’-dimethyl formamide. During the synthesis of the POT/WS<sub>2</sub> composites by SSI and ICP, an additional exfoliation of the WS<sub>2</sub> NPs was reported. In this work, we demonstrated the following: (a) the ICP method leads to POT/WS<sub>2</sub> composites, which contain repeating units of POT in the leucoemeraldine salt (LS) state, while (b) the ECP method leads to POT/WS<sub>2</sub> composites, which contain repeating units of POT in the emeraldine salt (ES) state. Capacitances equal to 123.5, 465.76, and 751.6 mF cm<sup>−2</sup> in the cases of POT-ES/WS<sub>2</sub> composites, synthesized by SSI, ICP, and ECP, respectively, were reported. |
