The conductivity of the doped PANI films at room temperature was reduced after thermal treatment, and it is dependent of the counterions. It was found that the conductivity stability of PANI–p-TSA and PANI–CSA is the best below 200°C. When the doped PANI films were placed in air, ...
The optimum temperature depends on the acid used and is, for the cases considered, higher than the one used in the procedures reported so far. In particular, pellets of polyanilines synthesized with H3PO4 are produced with conductivities up to 58 S/cm. 展开 关键词:...
Chemiresistance sensors work on the principle of change in resistance on exposure of gas. A standard sensor should satisfy the following characteristic features such as operation at room temperature, working in the ambient environment and no requirement of oxygen or air supply, no external stimulus ...
Furthermore, it indicates the improvement of the stability and efficiency of the PPL, as well as its high level of performance when comparing the efficiency/cell area with other research teams. Table 3 Efficiency comparison of the results of other group reported in ambient air process perovskite ...
The structure, morphology and thermal stability of the hybrid were characterized by various analysis methods. Compared with those reported in literatures, the hybrid-based sensor not only has high sensitivity, good selectivity and wide linear response to NH3 at room temperature of 21 °C but also ...

Supercapacitors have been gaining enormous attention owing to their high power density, fast charge-discharge rates, good cycling stability and wide operating temperature range. They are promising candidate as energy storage devices for electrical vehicles, power back-up, pacemakers, wearable electronics,...
In the beginning, the surface of TiO2/PANI/NCF displays a higher temperature (90.2°C) than that of the surrounding environment under light irradiation. Once water is transferred to the surface, the temperature gradually decreases and water will uniformly spread from the center to the edge. The...
Thus, the sensing material's stability to the temperature and humidity environment functions as a major factor in evaluating the sensor's performance. In this sense, we observed the rate of changes in responsiveness (S%) at 2 ppm C3H6O concentration, according to the changes in RH% (constant...
(sodium oleyl sulfate, 1 mg mL−1) was spread onto pure water subphase with a microsyringe. After 30 min, when the solvent was evaporated, theπ-Aisotherm was recorded at a continuous pressing speed for the barrier of 1 mm min−1at room temperature. In addition, aniline (...
