“…The, PANA and Au/copolymer nanocomposites are characterized by FTIR-ATR spectrophotometer and spectrum is given in Figure 2. The strong stretching vibration of carboxyl group (C=O) of PANA was at around 1688 cm -1 (Figure 2-A), however it was shifted to 1684 cm -1 in case of Au/copolymer nanocomposite (Figure 2-B) [9]. In the presence of 3-carboxy-N-(2-thenylidene)aniline, new vibrational bands at around 1247 cm -1 and 1502 cm -1 coresponding to C-C or C= C stretching of the thiophene ring were appeared.…”

In this study, gold/copolymer core−shell nanocomposites as a new metal-polymer composite have been obtained by in situ polymerization. During the polymerization, gold nanoparticles were highly stabilized throughout the copolymer matrix. Fabricated nanocomposites have been characterized by UV-Visible, and Attenuated total reflection -Fourier transform infrared (ATR-FTIR) spectrophotometry. Structure and morphology of synthesized nanoparticles were analyzed by atomic force microscopy (AFM) and Electron Microscopy/Energy-Dispersive X-ray Spectroscopy SEM/EDX. The electro-activity of synthesized Au/copolymer nanoparticles were studied with electrochemical impedance spectroscopy (EIS).

“…Polymerization conducted in the presence of Fe 2+ has been shown to proceed at a much greater rate than that conducted in the absence of a mediator, where it has been proposed that the main oxidative protagonist is the sulphate radical anion rather than APS itself [23]. While APS is the most common agent used for the polymerization of anthranilic acid and supporting monomers, metal ion oxidants such as Fe(III) [36,42,46], Cr(VI) [26,44,49,56,58,81], Pd(IV) [42], and Au(III) [61,63,74,76] have also been used to form polymeric structures-usually when the development of nanostructures is required, and these are discussed in more detail in Section 4.1.…”

“…In this case, oxidation of the aniline/anthranilic acid monomer leads to the simultaneous reduction of the metal ion, which then serves as the nanoparticle core. This strategy has been used for PAA [42,63] and various copolymer mixtures. Mallick et al (2008) employed palladium acetate in the presence of anthranilic acid to simultaneously oxidize the latter to PAA whilst reducing Pd(IV) to a metal.…”

Polyaniline has been utilized in various applications, yet its widespread adoption has often been impeded by challenges. Composite systems have been proposed as a means of mitigating some of these limitations, and anthranilic acid (2-aminobenzoic acid) has emerged as a possible moderator for use in co-polymer systems. It offers improved solubility and retention of electroactivity in neutral and alkaline media, and, significantly, it can also bestow chemical functionality through its carboxylic acid substituent, which can greatly ease post-polymer modification. The benefits of using anthranilic acid (as a homopolymer or copolymer) have been demonstrated in applications including corrosion protection, memory devices, photovoltaics, and biosensors. Moreover, this polymer has been used as a versatile framework for the sequestration of metal ions for water treatment, and, critically, these same mechanisms serve as a facile route for the production of catalytic metallic nanoparticles. However, the widespread adoption of polyanthranilic acid has been limited, and the aim of the present narrative review is to revisit the early promise of anthranilic acid and assess its potential future use within modern smart materials. A critical evaluation of its properties is presented, and its versatility as both a monomer and a polymer across a spectrum of applications is highlighted.

Electrically conducting polymers are increasingly being used as NIR fluorescence probes in the area of biomedical engineering via the application of a structural modification process. Peroxydisulphate (PDS) initiated the chemical polymerization process of anthranilicacid (AnA) in a nitrogen atmosphere at a temperature of 0 to 5 oC. Rosebengal (RB) was used as an end capping agent, and vigorous stirring was maintained with and without sand. The produced polymer and its nanocomposite were examined using instruments for UV-visible, TGA, DSC, SEM, EDX, FTIR, CV, FES, HRTEM, and XRD. The thermal stability of the resulting polymers was investigated using non-isothermal degradation kinetics. Additionally, the thermodynamic parameter values were determined. In the 3% weight Sand loaded PAnA system, a conductivity value of 4.31x10− 2 S/cm was recorded, signifying a 90.3% yield percentage. Sand was added, and this resulted in an increase in the rate of polymerization (Rp). The PAnA/Sand nanocomposite system has a higher photo-conversion efficiency of 1.49 percent as compared to the RB end capped PAnA system. The experimental results are scrutinized closely and compared to values reported in the literature.
