We report for the first time a rapid electrochemical synthesis of one-dimensional poly(2,5-dimethoxyaniline) nanorods (PDMA-NR) in the presence of surfactant. FE-SEM and TEM imagesconfirm the PDMA-NR formation and the average diameter of single rod sizes in the range of ~200–300 nm. An enzymatic glucose biosensor was fabricated through immobilizing glucose oxidase (GOx)into PDMA-NR matrix. The amperometric current response of PDMA-NR/GOx to glucose is linear in theconcentration range between 1 and 10 mM with a detection limit of 0.5 mM (S/N = 3). The PDMA-NR/GOxelectrode possesses high sensitivity (5.03 mA/mM), selectivity, stability, and reproducibility towardglucose.
Simple and rapid synthesis of polyaniline microrods and its electrical properties

We report a facile and surfactant assisted synthesis of polyaniline microrods (PANI-MR) by ‘‘single-step chemical oxidative polymerization’’ method. The morphology of the PANI-MR was investigated by fieldemission scanning electron microscopy (FE-SEM). The average diameter of single PANI-MR was calculated to be 1.3 mm. The physiochemical characterization was examined using UV–visible spectroscopy, Fourier transform infrared spectroscopy and cyclic voltammetry. The electrical conducting property of the PANI-MR was analyzed using four-probe measurement method.

<P>Herein, we demonstrate a synergistic approach involving polar-based oxide and polysulfide additives for effectively suppressing polysulfide dissolution during cycling. The MnO2 hollow spheres not only provide physical confinement for the polysulfide species but also enable strong chemical interactions between polysulfide species and oxides, while the added polysulfide furnishes a mass buffering effect and compensates for the capacity losses due to partial cathode dissolution during discharge. The capacity retentions of S/KB, S/KB/LiPS, S/KB/MnO2, and S/KB/MnO2/LiPS composite cathodes are 31%, 45%, 59%, and 91% respectively. The remarkable capacity retention of the S/KB/LiPS/MnO2 composite electrode is mainly attributed to the synergistic effect between MnO2 and polysulfide additives.</P>
