The key developments in polyaniline-carbon nanotube (PANI-CNT) composites are reviewed. Apart from in situ chemical polymerization and electrochemical deposition, a number of interesting approaches including the use of aniline functionalized CNTs and ultra- sound/microwave/γ-radiation initiated polymerization have been used in the preparation of composites. The structure and properties of these composites have been investigated by a va- riety of techniques including absorption, infrared (IR), Raman, X-ray photoelectron spec- troscopy methods, scanning electron and scanning probe microscopy techniques, cyclic voltammetry, and thermogravimetry. The experimental results indicate favorable interaction between PANI and CNTs. The CNT content in these composites controls their conductive, mechanical, and thermal properties. The most interesting characteristic is their easy dis- persibility in aqueous solution. The performance evaluation studies of PANI-CNT compos- ites in a number of applications including supercapacitors, fuel cells, sensors, and actuators are highlighted.

Polyaniline-carbon nanotube composites

19 May 2014 Supercapacitors are energy storage devices emerging as one of the promising energy storage devices in the future energy technology. In this perspective, rapid progress is made in the development of fundamental and applied aspects of supercapacitors. Various techniques have been developed specifically to estimate the specific capacitance. Numerous efforts were made in the literature to increase the specific capacitance value of the electrode materials. The electrode materials which have unique structural and electrochemical capacitance properties, such as high capacity and cyclic stability showed great supercapacitors performances. Recently, there are much new types of electrode materials were developed to play an important role in the capacitance behavior. In this review, we focused on the applications of various nanostructured electrode materials like carbon nanomaterials, metal oxides and conducting polymer towards highly efficient supercapacitors.

Recent Advancements in Electrode Materials for the High- performance Electrochemical Supercapacitors: A Review

Nanostructured ZnO thin film was prepared by DC reactive magnetron sputtering and characterized by X-ray diffraction, SEM, AFM, FT-IR spectroscopy, UV–vis spectroscopy and photoluminescence measurements. Under the conditions employed, the sputtered ZnO film was found to be polycrystalline with grain size varying between 70 and 100 nm. The absorption and photoluminescence spectral data indicated the presence of defects in the form of zinc interstitials and oxygen vacancies which could promote adsorption of gaseous species. Impedance technique was used to confirm adsorption of water vapor onto the sensor film. The chemiresistor sensor showed nearly a four order variation in resistance in the relative humidity range between 6.3 and 84% with a response and recovery time of 3 and 12 s respectively. The device exhibited high stability offering scope for developing a practical humidity sensor.
