A ternary polymer nanocomposite film composed of green-synthesized graphene quantum dots, polyaniline, polyvinyl butyral and poly(3,4-ethylenedioxythiophene) polystyrene sulfonate for supercapacitor application

Functional carbon dots derived from biomass and plastic wastes

“…The optimal composite system was designed as a prototype battery and utilized in electronic and portable devices. The authors also prepared CDs from rice flour by the hydrothermal method 172 and incorporated them The electrochemical impedance spectroscopy of the composite showed that the equivalent series resistance and RCT values were significantly lower than those of the original system. The composite (PVB/PANI/PEDOT:PSS + CDs 1 wt%) exhibited a higher pseudo capacitance value (4992.1 F g −1 cm −2 at 0.14 A g −1 ) than pure polymer and other PANI-based materials reported.…”

Development of soft polymer blend for copper ion detection by electrochemical route

“…The band observed at 1390 cm −1 was attributed to COO group 39 . Which shows chemical bonding between PVB and PEDOT:PSS molecule 32 . Shown in the Figure 1b these series of FTIR bands in blend system suggest that PVB/PEDOT:PSS blend was successfully modified.…”

“…PEDOT:PSS is a conducting polymer contributed electrons to the polymer system as donor. 19,31,32 We wanted to take advantage of the beneficial features of PEDOT:PSS and PVB to build a PVB/PEDOT:PSS blend which possess excellent conductivity and water stability. Therefore, the efficient combination of these two materials will make full use of their respective properties.…”

Porous nanosheet–nanosphere@nanosheet FeNi2-LDH@FeNi2S4 core–shell heterostructures for asymmetric supercapacitors

“…However, the development of active electrode materials is considered important in the long term. [11][12][13] Common electrode materials include conductive polymers (CPs), 14,15 transition metal oxides (TMOs) such as CuO, 16 MnO 2 and 17 NiFe 2 O 4 , [18][19][20][21][22] transition metal hydroxides (TMOHs) such as Co(OH) 2 23 and Ni(OH) 2 24 and transition metal sulphides (TMSs) such as NiS 2 , 25 CuCo 2 S 4 26 and NiCo 2 S 4 27 . CP electrodes exhibit high charge density and generate large Faraday capacitance, but they have poor mechanical properties and cycling stability.…”
