Poly(3,4-ethylenedioxythiophene) (PEDOT) films were produced by chemical oxidative polymerization (in-situ PEDOT) and coating aqueous dispersion (slurry PEDOT). Sheet resistance measured before and after heat treatment showed that slurry PEDOT film remained stable in air while in-situ film degraded resulting in a significant increase in resistance. Excellent stability of slurry film was credited to its PEDOT-rich core, Poly(styrenesulfonic acid) (PSS)-rich shell structure, and high molecular weight (M w ) PSS dopant while the degradation of in-situ PEDOT was attributed to oxidation by oxygen in air. Thermal analysis data supported this hypothesis. Fourier Transform Infrared (FT-IR) spectrometry and X-ray photoelectron spectroscopy (XPS) results indicated that C=C bond breaking and decreased doping level were responsible for poor stability of in-situ film in air.

“…3b shows the XPS results of S (2p). The XPS spectra of S (2p) for the S-EG composite have two peaks at 164.0 and 168.4 eV, corresponding to the state of S (S 8 ) 41 and S 6+ (R-SO 3 -R 0 like in polystyrene sulfonate), 42 respectively. Since we didn't observe any S (2p) peaks for EG, the 2p (S 6+ ) peak is not from the H 2 SO 4 which we used to prepare the graphite oxide.…”

Facile synthesis of a interleaved expanded graphite-embedded sulphur nanocomposite as cathode of Li–S batteries with excellent lithium storage performance

This paper reports the facile synthesis of a unique interleaved expanded graphite-embedded sulphur nanocomposite (S-EG) by melt-diffusion strategy. The SEM images of the S-EG materials indicate the nanocomposites consist of nanosheets with a layer-by-layer structure. Electrochemical tests reveal that the nanocomposite with a sulphur content of 60% (0.6S-EG) can deliver the highest discharge capacity of 1210.4 mAh g À1 at a charge-discharge rate of 280 mA g À1 in the first cycle, the discharge capacity of the 0.6S-EG remains as high as 957.9 mAh g À1 after 50 cycles of charge-discharge. Furthermore, at a much higher charge-discharge rate of 28 A g À1 , the 0.6S-EG cathode can still deliver a high reversible capacity of 337.5 mAh g À1 . The high sulphur utilization, excellent rate capability and reduced overdischarge phenomenon of the 0.6S-EG material are exclusively attributed to the particular microstructure and composition of the cathode.

“…PEDOT:PSS has extensively been used as buffer layer in organic optoelectronics and organic solar cells device applications [4,5]. Consequently, the degradation of PEDOT:PSS especially under atmospheric air containing oxygen and moisture, which influence the structure of this polymer, is crucial for the performance of organic electronic devices and it is still under investigation [5,6].…”
