Lithium iron phosphate (LiFePO 4 ) nanoparticles and lithium iron phosphate/halloysite (inorganic nanotubes) (LiFePO 4 /INT) nanocomposites were prepared by ultrasound-assisted synthesis in an aqueous solution of lithium hydroxide containing ammonium dihydrogen phosphate and ferrous chloride and used as cathode materials in lithium ion batteries. The performance of the cathode material was measured using cyclic voltammetry. The oxidation potential for LiFePO 4 polyaniline/nanotubes/anode cell was found to be in the range of 21.12 to 1.063 V while the reduction potential for lithium iron phosphate cell was in the range of 21.03 to 1.15 V.

“…In fact, the rise in the resistivity is thought to be due to the H-bonding interactions between the -OH groups of alcohols and the nitrogen atoms in PANI structure. As a result, the conformational rearrangements of the macromolecules are hindered which consequently impede the electron delocalization and charge transport through the polymer chains [33], [34]. In addition, the alcohol molecules trapped within PANI macromolecules can cause the chains to swell and break some of the conduction path for charge carriers, hence resulted in higher resistance.…”

This paper addresses the preparation of onedimensional nanostructured polyaniline (PANI) and polypyrrole (PPy). The Fourier transform infrared spectroscopy was used to characterize the chemical structure of the samples. The morphology of the samples was investigated by scanning electron microscopy and transmission electron microscopy. A nanofibrillar morphology was observed for the synthesized PANI and a nanotubular structure was obtained in the case of PPy. The alcohol sensing behaviors of PANI and PPy nanostructures were investigated for methanol, ethanol, propanol, and butanol, and the sensing mechanism of these systems has been discussed in detail. Both PANI and PPy systems were capable of detecting very low alcohols concentration (as low as 3 ppm) and demonstrated a linear behavior with a fast response/recovery performance especially in the case of ethanol vapor. The PPy-based sensor showed a better cyclability in response as compared with PANI when exposed to ethanol atmosphere. The surface characteristics of the PANI and PPy sensitive layers were investigated via atomic force microscopy. Ultraviolet-visible spectroscopy was used to study the effect of alcohol exposure on the electronic transport properties of nanostructured PANI and PPy layers.

Polypyrrole/indium tin oxide nanocomposites were synthesized via in situ miniemulsion polymerization of pyrrole monomer in the presence of indium tin oxide nanoparticles. Different nanocomposites were synthesized by different loadings of nano indium tin oxide. The morphology and nanoparticles distribution of the nanocomposites were characterized by electron microscopy. The results of XRD and TEM analysis showed that indium tin oxide nanoparticles were well placed in the polymeric structure of latex. FTIR analysis was used for the characterization of synthesized polypyrrole and its nanocomposites. TGA analysis was performed to investigate the thermal behavior of pristine polypyrrole and its nanocomposites. Conductivities of nanocomposites were measured by 4-point probe method and compared to the neat polymer.
