Electrochromic Properties of Polyaniline-Based Hybrid Organic/Inorganic Materials

Abstract: Hybrid materials based on polyaniline (PAni) were obtained by in situ polymerization of aniline with chitosan and/or organically modified clay (nanomer I-24) in HCl. The samples were characterized by Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM) and direct current (DC) electrical conductivity. Thin films of PAni, PAni-clay, PAni-chitosan and PAni-chitosan-clay were prepared by casting a solution of each sample in N-methyl-2-pyrrolidone (NMP) onto in… Show more

“…PAni was synthesized according to the method described by Silva et al [10] , in which 1.0 mL of freshly distilled aniline was dissolved in 10.0 mL of 1.0 mol L −1 HCl and the solution was cooled to −10 °C in an ice, NaCl and ethanol bath. Then, a solution containing 3.0 g of (NH 4 ) 2 S 2 O 8 dissolved in 40 mL of 1.0 mol L −1 HCl was slowly poured into the monomer solution, under vigorous stirring.…”

“…The FTIR spectra of neat Pani, electrospun PCL, and PCL/PAni mats are presented in Figure 4. The PAni FTIR spectrum shows the characteristic bands at 1584 cm -1 and 1488 cm -1 , which are assigned to the stretching vibration of quinoid rings and the stretching mode of benzonoid rings [9,10,34] , respectively. The bands at 1321 cm -1 refer to C-N stretching bonds of secondary amine group [35] , whilst the bands at 1158 and 829 cm -1 are attributed to the in-plane C-H bending of quinoid structure and the out-of-plane bending of C-H bonds in the aromatic ring.…”

“…However, they can be made oleophilic by exchanging the cations with organic ions like cetyl trimethyl ammonium bromide ions or cetyl trimethyl ammonium pyridinium ions etc., producing organoclay composites or polymer clay nanocomposites (PCNs). These composites are extremely investigated in material science and find widespread applications as adsorbents for heavy metal ions [2][3][4], ceramics and thin films [5], building materials [6], photocatalysts for wastewater treatment [7,8], drug delivery vehicle [9], bio-inspired materials [10], optoelectronic devices [11], ferrofluids [12], and hydrogel clay hybrids for pesticide and nutrient retention [13].…”
