“…4b, c). The decomposition temperature of DBSA [30] for hybrid gels with 0.8 mol/L nitric acid is from 240 • C to 370 • C, while the decomposition temperature for hybrid gels with 0.9 mol/L sulfuric acid begins at 190 • C. Then the weight loss up to 700 • C is corresponding to the decomposition of polyaniline itself and total weight loss for the hybrid gels with 0.9 mol/L sulfuric acid is also more than that with 0.8 mol/L nitric acid. The result is consistent with the analysis of IR (Fig.…”

“…Figure 5 shows the amplificatory bands of the region (1020–1060 cm −1 ) which is assigned to the SO stretching band [34–36], and the CC stretching band (side chain) of PP which is not influenced by temperature [37]. With the aid of computer analysis, curve‐fitting spectra of the SO stretching region were executed in the PP/CPP/PANI composite with various temperatures.…”

The previous studies suggest that hydrogen bond between chlorinated polypropylene (CPP) and polyaniline (PANI) plays a prominent role in the decision of polypropylene/CPP/PANI composites' electric property. In situ Fourier-transform infrared spectra were employed to detect and identify the relationship between the hydrogen bond and the temperature. Two kinds of hydrogen bond were carefully studied in the nitrogen-hydrogen bond (NÀ ÀH) stretching, sulfur-oxygen double bond (S¼ ¼O) stretching, and carbon-chlorine bond (CÀ ÀCl) stretching regions, using an iterative least-squares computer program to obtain the best fit of spectra. The ratio of absorptivity coefficients and the mole fraction of the ' 'free' ' and two kinds of Hbonded NÀ ÀH were calculated. There exists an apparent turning point in the curves of the relationship between the fraction of two kinds of H-bonded NÀ ÀH and temperature. This phenomenon also exists in the S¼ ¼O stretching region, and the turning point is at about 608C. The mole fraction of H-bonded CÀ ÀCl decreases, and that of ' 'free' ' CÀ ÀCl increases with increasing temperature. The enthalpy gap between the H-bonded NÀ ÀHÁ Á ÁO¼ ¼S and the H-bonded NÀ ÀHÁ Á ÁCl¼ ¼C dissociation was also obtained as 23.2 KJ/mol. POLYM. FIG. 7.

“…In this case, large molecular sized anions are trapped within the polyaniline matrix, thereby maintaining the polymer’s electronegativity in order to attract protons. Camphorsulfonic acid [ 147 , 148 , 149 ], dodecylbenzenesulfonic acid (DBSA) [ 150 , 151 ], and poly(2-acrylamido-2-methyl-1-propanesulphonic acid) (PAMPSA) [ 152 , 153 , 154 ] were reported to be the most effective organic acids used for this purpose. Furthermore, the use of such organic acids enhances solubility of the polymer and improves solution processability.…”

One dimensional polyaniline nanowire is an electrically conducting polymer that can be used as an active layer for sensors whose conductivity change can be used to detect chemical or biological species. In this review, the basic properties of polyaniline nanowires including chemical structures, redox chemistry, and method of synthesis are discussed. A comprehensive literature survey on chemiresistive/conductometric sensors based on polyaniline nanowires is presented and recent developments in polyaniline nanowire-based sensors are summarized. Finally, the current limitations and the future prospect of polyaniline nanowires are discussed.
