This research work presents a simple and effective way for preparation of polyaniline (PANI) nanofiber composites mixed with polyvinyl alcohol or polystyrene (PS) and their application for lead (Pb) removal from an aqueous medium. Interestingly, PANI/PS porous nanofibers show excellent performance as a one-step Pb removal technique from aqueous solutions. The efficiency of Pb removal is found to be more than 95%, which is pretty higher than the previously reported values of other nanocomposites, as Pb removal adsorbents. Furthermore, when pure PANI nanofibers cannot remove Pb in an efficient way, this is a straightforward method for separation from the solution. This is attributable to the high surface area of PANI-PS composites. This study also provides a simple and effective way for the development of new environmental cleaning materials. The PANI/PS composite nanofiber could be a good candidate for efficient Pb removal from wastewater and for deep purification of polluted water. The composite materials have been investigated in terms of morphology, chemical structure, thermal behavior, and defect evolution using Scanning Electron Microscopy, Fourier Transform Infrared Spectroscopy, Differential Scanning Calorimetry, Thermal Gravimetric Analysis, and Positron Annihilation Spectroscopy, respectively. To measure the adsorption capacity and intensity of adsorption, the adsorption data were fitted in Langmuir, and Freundlich models. J. VINYL ADDIT.

“…as can be seen in figure the characteristic peaks of the PAni.PS blend were shown at 1740 cm -1 (C=C stretching vibration of the quinoid ring), 1493 cm -1 (stretching vibration of C=C of the benzenoid ring), 1263 cm -1 (C-N stretching vibration), 1103 cm -1 (C-H in-plane defo rmation), 806 cm -1 (C-H out-of-plane deformation) selected to polyaniline. In addition, characteristic absorbtion band at 2968 cm -1 (methylene C-H stretching) are asigned to polystyrene [10].…”

Abstract:A polyaniline (Pani) blends films have been prepared successfully by the casting method. The Pani blends films of thickness 50 µm have been prepared from the Pani and PMMA, PS and POE at constant concentration. The Pani blends films are characterized by X-ray diffraction and Fourier transform infrared spectroscopy, the presence of characteristic bonds of Pani blends films were observed from FTIR spectroscopy technique. Electrical properties revealed that conductivity of Pani blends films at room temperature are 5.18 ×10 -9 , 9.23×10 -9 and 1.22 ×10 -8 S.cm -1 for Pani blends with PMMA , PS and PEO, respectively. Mechanical properties show variation values of tensile stress and hardness for different Pani blends films.
