The structure and electrochemical properties of poly(3,4-propylenedioxythiophene)/SnO₂nanocomposites synthesized by mechanochemical route

Abstract

In this study, the poly(3,4-propylenedioxythiophene)/ SnO 2 nanocomposites (PProDOT/SnO 2 ) with different contents of SnO 2 were successfully prepared by using hand grinding and ball milling methods, respectively. The effects of the synthesis methods and SnO 2 on the structure and electrochemical properties of the nanocomposites were deeply discussed. The results showed the structure of composites were highly affected by the increasing amount of nano-SnO 2 particles in reaction medium of hand grinding method than ball milling method. And, the PProDOT/SnO 2 nanocomposites from ball milling method displayed similar absorption spectra, and ball milling method promoted the uniform distribution of nano-SnO 2 particles in PProDOT matrix. However, PProDOT/SnO 2 nanocomposites from hand grinding method displayed the higher specific surface area and stronger synergetic effects between PProDOT and SnO 2 than that of PProDOT/SnO 2 nanocomposites from ball milling method. As a result, the PProDOT/SnO 2 nanocomposites from hand grinding method showed higher electrochemical activity than PProDOT/SnO 2 nanocomposites from ball milling method. Moreover, the specific capacitance and cycle stability of PProDOT/SnO 2 nanocomposites from both methods were higher than respective pure PProDOT. Among all the nanocomposites, PProDOT/15wt%SnO 2 nanocomposite from hand grinding method possessed the highest specific capacitance (259 F g 21

“…The sharp XRD patterns at 2Ɵ = 26.9°for PProDOT, 26.1°for CP1-1 and 26.9°for CP1-5 are attributed to the interchain planar ring stacking distance with plane (020) reflection. 82 The sharp XRD patterns at 2Ɵ = 29.2°for PProDOT and 18.8°1 9.77°,, 29.3°, 32.5°for CP1-1 are observed indicating a small degree of crystallinity coming from the PProDOT. 83,84 In contrast, P (ProDOT-EO-ester), CP1-5, CP1-25, and CP1-50 have an amorphous structure just like some other polythiophene derivatives.…”

“…Among them, the characteristic peaks at 1,495 and 1,323 cm 21 correspond to the C@C stretching in thiophene ring of PProDOT. The bands at 1,179, 1,130, and 1,049 cm 21 are assigned to the CAOAC stretching band of ethylenedioxy group [30,31]. The vibration bands at 925, 842, and 710 cm 21 originated from the vibration of CASAC bond in thiophene ring of PProDOT [30,32].…”

“…Thiophene based donor‐acceptor type organic conducting polymers showed impressive NLO properties [13,14] . Propylenedioxythiophene (PRDOT) and ethylenedioxythiophene (EDOT) are the trending thiophene based monomers which have shown tremendous performance as monomers for organic polymers with photocatalytic hydrogen production, [15] excellent thermal performance [16] attractive optoelectronic, [17] electrochemical [18,19] and electrochromic properties [20–23] and in light emitting diodes [24] . The flexible action of thiophene based monomers in diode components, field‐effect transistors, electroluminescent lamps, organic solar cells, nonlinear optical devices, organic LED, and other devices are an outcome of their effortless synthesis, good ionization potential, better charge carrying mobility, environmental stability, and the potential to adapt with varying chemical structures [25–31] .…”
