“…Moreover, most metal oxides and conducting polymers usually display electroactivity in narrow positive potential range in aqueous electrolyte and the electrochemical properties are improved as incorporating conductive polymer into metal oxide materials ,. Particularly, at presentsome works on incorporating MnO 2 into electrically conductive polymers such as PPy are considered as an effective method to improve the performance of the composite materials of metal oxide and conductive polymer ,,,. PPy and MnO 2 composite materials make up for the deficiency of PPy and MnO 2 .…”

In an aqueous mixture of manganese acetate, ammonium acetate and pyrrole, PPy and MnO2 composite materials (PPy‐MnO2) are synthesized by i‐t technology at 0.9 V vs. SCE. The influences of manganese acetate to pyrrole in the electro‐codeposition solution on morphologies and charge storage properties of the composite are discussed. PPy‐MnO2 composite materials as the electrode material exhibit a wide charge‐storage potential window of 1.2 V (between −0.3 and 0.9 V vs. SCE) and a high specific capacitance of 345.54 F g−1 at 2 mA cm−2. A symmetric flexible supercapacitor (PPy‐MnO2//PPy‐MnO2) is assembled by using PPy‐MnO2 composite electrodes. PPy‐MnO2//PPy‐MnO2 model supercapacitor displays almost 100% capacitance retention on the different bending angles. The energy density of 37.63 Wh kg−1 at the power density of 830 W kg−1 and an immense cyclic charge‐discharge stability, the specific capacitance is lost less than 3% after the 10,000 galvanostatic charge‐discharge cycles. The successful synthesis of high performance composite electrodes using electro‐codeposition method could open up new opportunities for high energy density supercapacitors.

“…Nanotechnology has ability to build materials at nano range [6]. In fact, the properties of substances dramatically change when their size is reduced to the nanometer range [7,8] as nanometer range particles have high surface to mass ratio [9]. In last few years, the development of polymer nanocomposites has offered new technology and favorable opportunities for commercial scale as well as all over society [10].…”

CdO nanoparticles, polyacrylonitrile, poly(butyl methacrylate) polymers have been synthesized by using green chemistry approach. Thereafter synthesized polymers were fabricated into nanocomposites by mixing nanoparticles to the polymers again using green chemistry protocol. Formation of CdO nanoparticles was confirmed by FT-IR and UV-Visible spectral data. The sizes of nanoparticles were determined by P-XRD and TEM analysis. P-XRD and TEM images of nanoparticles indicated that size of most of the nanoparticles lies in the range 5.74-22.25 nm. Formation of polymers and nanocomposites was confirmed by IR spectral studies. Morphology of nanocomposites was determined by SEM analysis. The thermal stability of polymers and nanocomposites was determined by TGA/DTA and found that the thermal stability of CdO/PAN & CdO/PBMA nanocomposites increased as compared to their polymers.

Coating individual bacterial cells with conjugated polymers to endow them with more functionalities is highly desirable. Here, we developed an in situ polymerization method to coat polypyrrole on the surface of individual Shewanella oneidensis MR‐1, Escherichia coli, Ochrobacterium anthropic or Streptococcus thermophilus. All of these as‐coated cells from different bacterial species displayed enhanced conductivities without affecting viability, suggesting the generality of our coating method. Because of their excellent conductivity, we employed polypyrrole‐coated Shewanella oneidensis MR‐1 as an anode in microbial fuel cells (MFCs) and found that not only direct contact‐based extracellular electron transfer is dramatically enhanced, but also the viability of bacterial cells in MFCs is improved. Our results indicate that coating individual bacteria with conjugated polymers could be a promising strategy to enhance their performance or enrich them with more functionalities.
