Synthesis of polythiophene/graphene oxide composites by interfacial polymerization and evaluation of their electrical and electrochemical properties

Abstract

Polythiophene/graphene oxide (PTh/GO) composite synthesized by interfacial polymerization showed a high value of conductivity and a capacitance of 99 F g−1 at a scan rate of 50 mV s−1.

Novel scalable synthesis of highly conducting and robust PEDOT paper for a high performance flexible solid supercapacitor

“…Even though interfacial polymerization is common in the case of polyaniline, 51,52 polypyrrole 53,54 and polythiophene, 55,56 there have been few reports on the interfacial polymerization of PEDOT. Most reports mention the use of surfactants, [57][58][59][60] but surfactant always has a negative impact on the conductivity of PEDOT.…”

PTh/Co3O4 nanocomposites as new conducting materials for micro/nano‐sized electronic devices

“…). The absorption bands at 623 and 1,031 cm −1 are assigned to stretching vibration of C‐S and stretching vibration of C‐C, respectively . The peaks at 1,398 and 1,634 cm −1 belong to C = C symmetric and asymmetric stretching vibrations, respectively .…”

Exploration of polythiophene/graphene, poly(methyl methacrylate)/graphene and polythiophene-co- poly(methyl methacrylate)/graphene nanocomposite obtained via in-situ technique

“…In PTh/Gr 0.5 nanocomposite, a shift in PTh diffraction peak was observed at 2y ¼ 22.9 (Figure 5b), which was in agreement with the literature. 25 While in the case of PMMA/Gr 0.5 nanocomposite (Figure 5e), the PMMA broad peak emerged at 2y ¼ 13.8 and the less intense graphitic structure broad peak appeared at 2y ¼ 26.8 . A strong intense peak at 27 is usually reported for graphitic structure.…”

“…A dark brown mixture was formed, which was filtered and the precipitates were washed several times with distilled water to obtain neutral pH. The product was dried at 70 C. 25 Preparation of PTh/Gr nanocomposite One gram of PTh was dissolved in 10 mL of DMSO and 0.1 g graphite was added to it. The mixture was first ultrasonicated for 48 h at room temperature.…”
