“…The thermogram of polyaniline emeraldine base form shows a weight loss of 7-8% upto 100℃, a weight loss of 22% from 100-450℃ and a weight loss of 40% from 450-800℃. Our data are found in good agreement with the data reported in literature [31][32][33], which confirms the reliability of our results. When polyaniline was mixed with polystyrene sulphonic acid in different compositions, i.e.…”

Polyanilines are synthesized by free radical chemical oxidative polymerization of aniline & o-toluidine using ammonium persulphate as an oxidant in protonic acid medium. These polymers have been introduced into polystyrene sulphonic acid (PSSA) in 2:1, 1:1, 1:2 compositions for the preparation of composite materials. The composite samples so obtained are thermally characterized by thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), X-ray diffraction, and FTIR spectra. The incorporation of polymer in PSSA has been endorsed by FTIR analysis. TGA data reveals that the (Polyaniline/Polystyrene sulphonic acid) PANI/PSSA (2:1) and (Poly o-toluidine/Polystyrene sulphonic acid) POT/PSSA (2:1) composites show better thermal stability than their 1:1 and 1:2 counterparts. Steric hindrance of -CH 3 group present in ortho position and sulphonic acid group of PSSA affects the thermal behaviour of composites. Two-step transitions are clearly reported from the DSC thermograms of polyanilines/PSSA composites and non-reversing chemical cross-linking reaction was further confirmed by X-ray diffraction and DSC thermograms.

In this research, a simple method was used to synthesize poly(aniline-co-m-aminobenzoic acid) also known as P(ANI-co-m-ABA) composite polystyrene (PS) nanofibers by using in situ chemical polymerization technique. The copolymer was polymerized on electrospun PS nanofibers mats with varied monomers solution concentration and the polymerization time. P(ANI-co-m-ABA) was also polymerized on PS films were prepared for comparison. The conductivity of the composites was studied and the result showed addition of graphene (GP) into the composites improved the conductivity of the composites. The composites of P(ANI-co-m-ABA)/PS nanofibers and films were characterized by Fourier transform infra-red (FTIR), thermogravimetric analysis (TGA) and ultraviolet visible (UV-vis) spectroscopy. Surface morphology of the composite was studied by scanning electron microscopy (SEM).Keywords: poly(aniline-co-m-aminobenzoic acid), nanofibers, electrospinning Abstrak Dalam kajian ini, satu cara mudah telah digunakan untuk sintesis poli(anilina-ko-m-asid aminobenzoik) atau diringkas sebagai P(ANI-co-m-ABA) komposit polistirena (PS) fiber nano dengan menggunakan teknik pempolimeran kimia in situ.

“…4a represents the TGA curves of the polyanilines determined through weight loss (%) data obtained between 30 and 400 °C. It was observed that the PANIs showed two-step mass loss processes which were similar to the reported observations [46]. The first process around 60 to 140 °C was attributed to the expulsion of water and dopant from the PANI matrix.…”

Polyaniline /sawdust /titanium oxide (PANI/SD/TiO 2 ) composite was chemically synthesised by insitu polymerization of aniline monomer in acidic medium containing sawdust and titanium oxide. The structure and morphological variations of PANI/SD/TiO 2 composite were interrogated by means of spectroscopy (FTIR, UV-visible, thermal gravimetric (TG) analyzer, X-ray diffraction (XRD), scanning electron microscope (SEM) and transmission electron microscope (TEM). Noticeable spectral and morphological changes were observed compared to pristine PANI thus, strongly suggesting chemical interaction between compounds present in the composite. Batch experiments were adopted in examining the adsorption kinetics and isotherm of selected polychlorinated biphenyl (PCB) congeners (PCB: 28, 52 and 101). Results indicate that PANI/SD/TiO 2 can be used as a novel, effective and low-cost adsorbent material for lower Chlorinated PCB remediation (PCB 28). Adsorption equilibrium studies followed Freundlich for PCB 52 and Langmuir models for PCB 28 and 101. While the adsorption kinetics were best described by pseudo-second-order (PCB 28 and PCB 52) and intraparticle diffusion models (PCB 101).
