A new generation multihollow opaque polymer pigment was synthesized by suspension polymerization of water-in-oil-in-water emulsion method, where methyl methacrylate and ethylene glycol dimethacrylate monomer mixture was used as oil phase. The effects of surfactant and cosurfactant composition in terms of hydrophilic/lipophilic balance on the stability of the water-in-oil emulsion and the size of water droplets were studied. Low droplet sizes and the optimum stability were obtained with Span 80&Tween 80 surfactant mixture at an HLB value of 8. The desired size distribution was obtained at monomer/surfactant/water ratio of 75.5/9.4/15.1 at an ultrasonic mixing power of 80 W lasting for 30 s. The surface morphology and hollow structure of polymer pigments were analyzed by scanning and transmission electron microscopy techniques. L*a*b color and gloss properties of polymer pigments were examined. The opacity values were assessed by contrast ratio measurements, and the pigments provided up to 97.3% opacity with 50% v/v solid content in resin. In addition, the pigments exhibited low gloss values and yielded matte films. (c) 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 43696.

Characterization and Electrical Conductivity of Poly(ethylene glycol)/Polyacrylonitrile/Multiwalled Carbon Nanotube Composites Aqeel, Salem M.; Kucukyavuz, Zuhal (Wiley, 2011-01-05) Polymer blends based on poly(ethylene glycol), polyacrylonitrile, and multiwalled carbon nanotubes (MWNTs) were prepared by the solvent cast technique from the dispersion of the MWNTs in the concentration range 0-3.45 wt %. The interaction of the MWNTs with the polymer blend was confirmed by a Fourier transform infrared (FTIR) spectroscopy study. The thermal properties of the polymer blend with the MWNTs were carried out by means of differential scanning calorimetry (DSC). It was evident from DSC that the p...
Synthesis and Characterization of a New Conducting Polymer Based on 4-(2,5-di-2-thiophen-2-yl-pyrrol-1-yl)-phthalonitrile Yavuz, Arzu; Bezgin, Buket; Önal, Ahmet Muhtar (Wiley, 2009-12-05) A new conducting polymer was synthesized by electrochemical polymerization of 4-(2,5-di-2-thiophen-2-yl-pyrrol-1-yl)-2-phthalonitrile (SNS-PN). Electrochemical polymerization of SNS-PN was performed in acetonitrile/0.2M LiClO4 solvent/electrolyte couple. Characterizations of the resulting polymer P(SNS-PN) were carried out by cyclic voltammetry, UV-vis, and Fourier transform infrared (FTIR) spectroscopic techniques. Spectroelectrochemical studies revealed that P(SNS-PN) has an electronic band gap of 2.45 eV...
Conducting polymer composites: Polypyrrole and poly(vinyl chloride vinyl acetate) copolymer Balci, N; Bayramli, E; Toppare, Levent Kamil (Wiley, 1997-04-25) Composites of a polypyrrole (PPy) and poly(vinyl chloride-vinyl acetate) copolymer (PVC-PVA) were prepared both chemically and electrochemically. An insulating polymer was retained in the blend and the thermal stability of the polymer was enhanced by polymerizing pyrrole into the host matrix in both cases. The composites prepared electrochemically gave the best results in terms of conductivity and air stability. (C) 1997 John Wiley & Sons, Inc.
Conducting Polymer Composites of Multiwalled Carbon Nanotube Filled Doped Polyaniline Yilmaz, Faris; Kucukyavuz, Zuhal (Wiley, 2009-01-15) A multiwalled carbon nanotube (c-MWNT)/polyaniline (PANI) composite was synthesized by an in situ chemical oxidative polymerization process. With the carbon nanotube loading increased from 0 to 30 wt %,, the conductivity also increased and became weakly temperature-dependent. Fourier transform infrared spectroscopy studies showed that the synthesis by an in situ process led to effective site-selective interactions between the quinoid ring of the PANI and the multiwalled nanotubes, facilitating charge-transf...
Electrosynthesis of polyfuran in acetonitrile-boron trifluoride-ethyl ether mixture and its device application Tirkeş, Süha; Önal, Ahmet Muhtar (Wiley, 2007-01-15) Electrochemical polymerization of furan was achieved in acetonitrile/boron trifluoride/ethyl ether (CH3 CN/BF3/EE) mixture in the presence of tetrabutylammonium tetrafluoroborate via constant potential electrolysis at 1.4 V versus Ag/AgCl. Electrochemical behavior of furan was investigated in the same solvent mixture of varying ratios, utilizing cyclic voltammetry. Free-standing polyfuran (PFu) films were obtained in CH3CN/BF3/EE mixture (2/4/4; v/v/v) and characterized using FTIR spectroscopic technique. S...
