The possibility of grafting between conducting polymers, like polypyrrole (PPy) and polyaniline (PAn), and insulating polymers, such as polybisphenol A carbonate (PC) and polyamide (PA), is studied via semi-empirical methods using the AM1 parametrization. Several experimental studies on the issue have previously revealed that a chemical interaction exists between the couples (PAn-PC, PPy-PC and PPy-PA) during the electrochemical synthesis of PAn and PPy in the insulating host matrices. Here we present additional theoretical evidence indicating that such grafting is possible, at least for small oligomers.

Development of a novel PANI@WO3 hybrid composite and its application as a promising adsorbent for Cr(VI) ions removal Hsini, Abdelghani; Naciri, Yassine; Laabd, Mohamed; Bouzıanı, Asmae; Navío, J.A.; Puga, F.; Boukherroub, Rabah; Lakhmiri, Rajae; Albourine, Abdallah (2021-10-01) In the current study, an in-situ oxidative polymerization method was used to synthesize polyaniline-coated tungsten trioxide biphasic composite (PANI@WO3). The as-developed composite material properties were elucidated using different characterization tools such as X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), N2 sorption-desorption isotherm, and X-ray photoelect...
The characterization of polyaniline and polypyrrole composites by pyrolysis mass spectrometry Hacaloğlu, Jale; Kücukyavuz, Zühal (2009-09-05) hi this work, direct insertion probe pyrolysis mass spectrometry technique was applied to investigate the thermal and structural characteristics of electrochemically prepared polyaniline (PANI), polypyrrole (PPy), and their composites/copolymers synthesized either by electrochemical polymerization of pyrrole on PANI-coated electrode (PANI/PPy) or by coating PANI on PPy (PPy/PANI) in H(2)SO(4) solutions. It has been determined that the polymer first coated on the electrode degraded to a certain extent during...
On the Possibility of a Polymer-Like Nanorod Based on Columnar Stacked Single Benzenoid Carbon Rings Malcıoğlu, Osman Barış (American Scientific Publishers, 2009-04-01) The properties of a polymer like nanorod based on columnar stacked layers of a single C-6 ring is investigated using density functional theory, in a plane-wave basis set and utilizing an ultrasoft pseudopotential. In this manner, the existence possibility of an unsubstituted, small cross section columnar pi-conjugated nanorod is aimed to be inferred via the calculated physical properties and bulk energetics. Two possible geometries for such a structure is presented in conjunction with previous work. The sys...
Studies on interaction of electromagnetic waves with barium hexaferrite ceramics Gürkan, Nurdan; Timuçin, Muharrem; Department of Metallurgical and Materials Engineering (2008) M-type barium hexaferrite powders doped with titanium and/or cobalt have been synthesized according to the stochiometric formulations BaFe(12 (4/3)x)TixO19, BaFe12-xCoxO19 , BaFe12-2xTixCoxO19 (x varying from 0 to 1.5 with an increment of 0.5) by the mixed oxide approach. The powders were used to manufacture small ceramic tiles by sintering each composition at 1250 °C with soaking times ranging from 1 to 16 hours. XRD work revealed formation of the magnetoplumbite crystal structure in all ceramics. The var...
Development of alumina supported ternary mixed matrix membranes for separation of H-2/light-alkane mixtures Topuz, Berna; Yılmaz, Levent; Kalıpçılar, Halil (2012-10-01) Ternary component mixed matrix membrane was prepared from PES, SAPO-34 and 2-hydroxy 5-methyl aniline on a macroporous alumina disk by the solvent evaporation method in order to investigate the effect of existence of an inorganic support. The membrane and its pure PES/Alumina counterpart were characterized by single gas permeability measurements of H-2, CH4, C2H6 and C3H8. The corresponding H-2/CH4 selectivities of membranes were 71.3 and 41. The membranes were also used to separate equimolar mixtures of H-...
