Combination pigments were synthesized by the deposition of copper phthalocyanine and tetracarboxamide copper phthalocyanine on a mica-titania pigment in dimethyl formamide solvent to improve color properties. The MIR and XRD analyses were performed to observe the crystal transformations of the pigments on the substrate. The stable beta form of copper phthalocyanine normally preferred in paint applications was obtained at 90 degrees C and 120 degrees C, while tetracarboxamide copper phthalocyanine remained amorphous at all temperatures experimented. Pigment surface morphologies were investigated by SEM analysis. Copper phthalocyanine crystalline rods were observed on the mica-titania substrate, however, the tetracarboxamide copper phthalocyanine pigment did not exhibit any such crystalline structure due to its amorphous structure, which was confirmed by XRD analysis. Furthermore, nitrogen elemental analysis was performed to determine the amount of copper phthalocyanines adsorbed to the mica-titania surfaces at different temperatures. The resulting combination pigments showed enhanced luster, good dispersion, hue, and high color intensity.

Synthesis and characterization of copper phthalocyanine deposited mica titania pigment Topuz, Berna Burcu; Gündüz, Güngör; Department of Polymer Science and Technology (2010) In the present work, anatase and rutile titanium dioxide (TiO2) coated lustrous mica pigments were prepared by heterogeneous nucleation method. Anatase-rutile phase transformation of the TiO2 on mica substrate was achieved by coating very thin layers of tin (IV) oxide on mica surfaces prior to TiO2 deposition. Muscovite mica, which was used in the experiments was sieved, pre-treated with sodium bicarbonate and decantated before coating process. The surface morphology of mica titania pigments and anatase-rut...
Synthesis, crystal structure and characterization of new transition metal compounds of bromophenols: Bis(2,4,6-tribromophenolato) di(N-methylimidazole)M(II) (M=Co, Cu) Camurlu, P; Yılmaz, Ayşen; Tatar, L; Kisakurek, D; Ulku, D (Wiley, 2005-03-01) Bis(2,4,6-tribromophenolato)di(N-methyl imidazole)M(II), where M stands for cobalt and copper metals, was synthesized via reaction of the corresponding metal sulphate and 2,4,6-tribromophenolate in aqueous media in the presence of N-methyl imidazole and sodium hydroxide. Although various crystallization procedures were applied only cobalt complex was obtained as single crystals. The Co(II) ion has a distorted octahedral enviroment involving two O atoms and two N atoms of the Bis(2,4,6-tribromopbenolato)di(N...
Characterization and enhancement of IR optical and tribological properties of DLC films synthesized by RF-PECVD Taburoğlu, Vahit Eren; Özenbaş, Ahmet Macit; Akata Kurç, Burcu; Department of Micro and Nanotechnology (2017) This thesis analyzes the hydrogenated amorphous diamond like carbon (a-DLC) films coated on aluminum substrates by the technique of plasma enhanced chemical vapor deposition (PECVD). Effects of film thickness, hydrogen content and RF power on the tribology, optical characteristics and structure are observed and studied in detail. DLC films have compressive intrinsic stresses by default. Surface topography revealed by an interferometer shows that too low/high compressive stress is detrimental to the film. In...
Formation and characterization of infrared absorbing copper oxide surfaces Arslan, Burcu; Erdogan, Metehan; Karakaya, İshak (2017-04-30) Copper oxide formation has been investigated to combine the advantages of producing different size and shapes of coatings that possess good light absorbing properties. An aqueous blackening solution was investigated and optimum composition was found as 2.5 M NaOH and 0.225 M NaClO to form velvet copper oxide films. A two-step oxidation mechanism was proposed for the blackening process by carefully examining the experimental results. Formation of Cu2O was observed until the entire copper surface was covered ...
CHARACTERIZATION OF CARBON-SUPPORTED PT-SN BIMETALLIC CATALYSTS FOR THE ELECTROCHEMICAL OXIDATION OF METHANOL Gökağaç Arslan, Gülsün; KENNEDY, BJ; CASHION, JD; BROWN, LJ (1993-01-01) Carbon-supported platinum oxide-tin oxide samples have been studied as electrocatalysts for methanol oxidation. The Teflon-bonded electrodes are found to be poor electrocatalysts. X-Ray photoelectron and Mossbauer spectroscopy, together with electron microscopy, have been used to determine the nature of the bimetallic crystallites. Differences in the activity of various Pt-Sn-containing electrodes for methanol oxidation are discussed.
