“…27,[30][31][32][33] In addition, the electron orbitals of the cation in the zeolite framework are other factors affecting the electrical conductivity. 80CuNaY shows a higher value of the electrical conductivity than 80NiNaY and 80FeNaY, respectively, because of the charge-balanced ion size.…”

In the case of Na + , which is an alkaline cation, the electrical conductivity of NaY is lower than those of 80CuNaY and 80 NiNaY due to the void size within the zeolite.…”

Doped poly(p-phenylene vinylene) (dPPV) is mixed with modified zeolite Y to improve the selective and sensitive response of zeolite Y toward three different ketone vapors (acetone, methyl ethyl ketone, and methyl iso-butyl ketone), which are known as the toxic components. Zeolite Y (Si/Al 5.1, Na + ) or NaY is ion exchanged with transition cations, Cu 2+ , Ni 2+ , and Fe 2+ , at 80% cation exchanged to prepare 80CuNaY, 80NiNaY, and 80FeNaY. In this work, the effects of transition cations, ketone vapor type, and ketone vapor concentration are systematically investigated. The highest electrical conductivity response and sensitivity toward acetone vapor at the vapor concentration of 30,000 ppm is obtained with 80CuNaY, whereas 80FeNaY shows the lowest values due to the electrostatic interaction between the zeolite framework and the cation. dPPV is mixed with 80CuNaY and exposed to the three ketone vapors. The electrical conductivity response and sensitivity of the composites toward acetone exhibits the highest values, whereas with MIBK they show the lowest value. After mixing of 80CuNaY with dPPV, the minimum vapor concentration toward acetone vapor decreases from 9 to 5 ppm. The response of the composite is irreversible as evidenced by Fourier transform infrared and atomic force microscopy techniques. C 2014 Wiley Periodicals, Inc.

Zeolites are known to provide high chemical stability, high porosity, high surface area, high selectivity, and adsorption properties. Nevertheless, zeolites still possess low electrical conductivity. The processes for improving the electrical conductivity of a zeolite are through adjusting the Si/Al ratio of zeolite, the ion-exchange process, and blending with conductive polymers (CPs). [5][6][7][8]14 The ion-exchange processes with alkaline, alkaline earth, and transition metals are expected to change the response and selectivity properties of zeolites. The ion-exchange process combined with blending a CP into the zeolite matrix has been shown to effectively improve the electrical conductivity of the zeolite for detecting toxic gases and chemical vapors. [5][6][7][8][14][15][16][17][18][19][20][21][22][23][24] CPs are the other type of materials, which can be used as gassensing materials as they show the high electrical conductivity, magnetic, and optical properties. One of the CPs, which has been widely used in the gas-sensing application, is poly(p-phenlene vinylene) (PPV) because it has a high electrical conductivity, good mechanical properties, good chemical stability, and ease in synthesizing. 25,26 A positive or negative response of doped PPV or dPPV depends on the electrophilic or nucleophilic nature of the gases or chemical vapors. Although dPPV exhibits a high electrical conductivity, its selectivity and adsorption properties

In this study, 3-octylthiophene (3OT) and its nanocomposites with TiO 2 (3OT/TiO 2 ) were electrochemically synthesized in different initial monomer concentrations (50, 75, 100, and 150 mM) in 0.1 M tetraethylammonium tetrafluoroborate (TEABF 4 )/acetonitrile (CH 3 CN) on a glassy carbon electrode (GCE). The best modified electrodes, which were taken from the optimum conditions of redox behaviors, were also electropolymerized in 0.5 M oxalic acid/acetonitrile (CH 3 CN) solution on Al1050 electrode. The modified Al1050 electrodes were characterized by optical microscope, FTIR-ATR, SEM-EDX, and EIS. The optimum conditions of the electrocoated P(3OT)/Al1050 and P(3OT)/TiO 2 nanocomposites on Al1050 electrode were investigated for corrosion performances against 3.5% NaCl solution. The corrosion tests were performed by EIS and Tafel extrapolation plots together with the equivalent circuit model of R s (Q c (R c (Q p R ct ))). P(3OT)/TiO 2 nanocomposite films showed higher protection efficiency (PE ¼ 89%) than P(3OT) films (PE ¼ 81%). The P(3OT)/TiO 2 nanocomposite films coated on Al1050 electrodes may be used in industrial applications of corrosion protection against salt water.
