Preparation, Characterization, and Conductivity of Polyaniline Doped with 12-Tungstoboric Acid

Synthesis and catalytic performance of cesium and potassium salts of aluminum substituted tungstoborate for pyrolysis of polyethylene waste to petrochemical feedstock

“…The synthesized material was characterized by various spectroscopic and surface-based techniques. FTIR spectrum revealed Keggin structure of both unsubstituted 12-tugstoborate (KB) [33,34] and aluminum substituted tungstoborate (KAB and CsAB) [35,36] [39,40]. The observed shift in B-O a stretching frequency is 26 cm -1 that is consistent with earlier reports for transition metal substituted Keggin polyoxometalates [39,40].…”

A New Way to Prepare MoO3/C as Anode of Lithium ion Battery for Enhancing the Electrochemical Performance at Room Temperature

“…In contrast, pristine MoO 3 without carbon was obtained by directly calcining AMo-PANI at 500 o C in air for 1 h. The samples were characterized by powder XRD (DX-2700B X-ray diffractometer, Cu Kα, λ = 1.54184 Å, China), FT-IR (Bruker Vertex 70 IR spectrometer, 4000-400 cm -1 , Germany) and FE-SEM (SU8010, 3.0 kV, Japan). The conductivities of different samples were measured by four-terminal method described previously [25]. In this measuring system, the 2400-C source measure unit (Tektronix, America) served as current source and the 34401A digital multimeter (Agilent, America) with 6 1 / 2 digital resolution served as voltage meter.…”

“…Aniline (AN) was distilled under reduced pressure and stored in the refrigerator before being used. AMo-doped polyaniline was synthesized by a method described in the literature [25]. Firstly, 4.0 g of AMo and 2 mL of AN were dissolved in a HCl solution (1 M, 100 mL) under ultrasonication to form solution A.…”

Synthesis, Electrical Conductivity, and Dielectric Behaviour of Polyaniline Doped with H2SO4; HCl and (HCl + NaNO2) Mixture

“…The acid doping of polyaniline generates suitable soluble counterions which improves the processibility of such conducting polymers. The acid doping of PANI is capable of polyaniline protonation along with providing suitable functional groups to the polymer backbone, making the polymer chemically stable, electrically conductive along with increasing the solubility factor of the polymer [13][14][15][16] . The degree of protonation can affect the dielectric, electrical conductivity, and other properties of PANI.…”
