“…For PEDOT:PSS/ PVA, except for above bands, the absorption peak also appears at 1092 cm -1 . The absorption peaks located at 2924 and 2853 cm -1 are assigned to the asymmetric stretching of CH 2 from PSS backbone; the peaks located at 1516, 1384, 1054 and 983 cm -1 are attributed to the stretching vibration of the thiophene ring, the C-C/C=C of the quinoidal structure, the C-O-C bond and the C-S bond from PEDOT and the peak located at 1092 cm -1 is ascribed to the C-O stretching vibration of the hydroxyl group in PVA [20,31,32]. All these typical absorption peaks indicate the successful coating of PEDOT:PSS/PVA on the nano-Sn particles.…”

A novel nano-Sn particle/poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate)/poly(vinyl alcohol) core-shell hierarchical composite (nano-Sn/ PEDOT:PSS/PVA CSHC) was fabricated for the first time and evaluated as a high-performance anode material in lithium ion batteries (LIBs). The core-shell hierarchical structure of the composite was revealed by field-emission scanning electron microscope and transmission electron microscope; the components of the composite were investigated by X-ray diffraction and fourier transform infrared spectroscopy; the nano-Sn particle content in the composite was obtained by thermogravimetric analysis and the electrochemical performance was studied by galvanostatic charge/discharge cycling tests and electrochemical impedance spectroscopy. When used as LIB anode material, the nano-Sn/PEDOT:PSS/PVA CSHC electrode exhibited high reversible capacity (568 mA h g -1 after 100 charge/discharge cycles at a current density of 100 mA g -1 ), superior cycling stability (capacity retention of 66.0 % after 100 cycles), good rate performance (143 mA h g -1 at 1500 mA g -1 ) and low charge transfer resistance compared to pristine nano-Sn particle and nanoSn/PEDOT:PSS composite electrodes. The improved electrochemical performance can be attributed to the coreshell hierarchical structure. The results show that the nanoSn/PEDOT:PSS/PVA CSHC is a promising anode candidate for next-generation LIBs.

“…Polyvinyl alcohol (PVA) is a semi-crystalline polymer, nontoxic, biocompatible and noncarcinogenic. Its hydrophilicity is an advantage for its applications in the formation of composite films [21]. PVA possesses good dimensional stability and photo-stable upon UV-visible light irradiation.…”

Cobalt oxide (Co 3 O 4 ) nanoparticles (NPs), with average crystallite size<61 nm, were prepared by a sol-gel method. Two allowed direct optical band gaps of 1.445 and 1.915 eV are found for Co 3 O 4 NPs. Sodium carboxymethyl cellulose (Na-CMC)/polyvinyl alcohol (PVA) blend was doped with Co 3 O 4 at different concentrations<1.0 wt.% to study the electrical and dielectric properties of these nanocomposite films. Scanning electron microscopy images revealed a good dispersion of Co 3 O 4 NPs on the surface of the CMC/PVA films. The current-voltage characteristics are of non-ohmic behavior. The dielectric permittivity (ε') was studied in the frequency and temperature range of 5.0 kHz-5.0 MHz and 308-408 K and was found to depend on the Co 3 O 4 content. The dielectric loss (ε^) also increases and shows wave-like behavior with increasing Co 3 O 4 ratio. Increasing Co 3 O 4 NPs content leads to the formation of more number of three-dimensional semiconducting connected networks inside CMC/PVA matrix, leading to increasing both DC and AC conductivities. The correlated barrier hopping (CBH) is the most suitable mechanism to explain the AC conduction behavior in the Co 3 O 4 / Na-CMC/ PVA nanocomposite films.

A composite of poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) and zinc stannate (ZnSnO 3 ) has been introduced for impedancebased humidity sensing, owing to its high sensitivity, good stability, very fast response ($0.2 s) and recovery time ($0.2 s), small hysteresis, repeatability, low-cost fabrication and wide range of sensitivity. Both materials were mixed in three different weight percentage ratios, to optimize the performance of the sensors. Best response was observed for 5 wt.% PEDOT:PSS and 5 wt.% ZnSnO 3 . The impedance of the sensor was dropped immensely from 1.5 MX to 50 kX by changing relative humidity from 0% to 90%. The reason for this improvement in sensitivity was analyzed by virtue of sensing mechanisms and different characterizations (three dimensional (3D) nano-profiler, optical microscope, and fourier transform infra-red (FTIR) spectroscopy) revealing the surface morphology and chemical structure of the film. Due to its response and ability to sense human breath and skin humidity, it is suitable for environmental, artificial skin and food industry applications.
