A series of blends of poly(vinyl chloride) (PVC) and low density polyethylene (LDPE) are prepared and examined. Plasma treatment is applied to one of the components (LDPE) in order to affect the degree of compatibility. For this purpose, different monomers, such as carbon tetrachloride and vinyl chloride, are used. Tensile test results for all the blend samples, with and without plasma-treated LDPE, are compared. The surface energy results of blends prepared from untreated and treated LDPE-PVC showed considerable differences, with appreciable increases for the latter, indicating an increase in the work of adhesion as a result of the plasma surface modifications applied. The tensile test results and the measured surface energies are found to show a similar parallel behaviour.

Synthesis and characterization of waterborne and phosphorus-containing flame retardant polyurethane coatings
Celebi, F; Aras, L; Gündüz, Güngör; Akhmedov, IM (Springer Science and Business Media LLC, 2003-09-01)
Phosphorus-containing flame retardant water-dispersed polyurethane coatings were produced by incorporating different amounts of a phosphorus compound onto the polyurethane main chain. The novel phosphorus containing compound (phosphorus phenyl dihydroxy) was synthesized in three steps using benzaldehyde, pentaerythritol, phenyl phosphonic dichloride, and acetic acid.
Thermal evolution of structure and photocatalytic activity in polymer microsphere templated TiO2 microbowls
Altunöz Erdoğan, Deniz; Polat, Meryem; Garifullin, Ruslan; Guler, Mustafa O.; Ozensoy, Emrah (Elsevier BV, 2014-07-30)
Polystyrene cross-linked divinyl benzene (PS-co-DVB) microspheres were used as an organic template in order to synthesize photocatalytic TiO2 microspheres and microbowls. Photocatalytic activity of the microbowl surfaces were demonstrated both in the gas phase via photocatalytic NO(g) oxidation by O-2(g) as well as in the liquid phase via Rhodamine B degradation. Thermal degradation mechanism of the polymer template and its direct influence on the TiO2 crystal structure, surface morphology, composition, spe...
Electrical and mechanical properties of carbon black reinforced high density polyethylene/low density polyethylene composites
Altıntaş, Bekir; Küçükyavuz, Zuhal; Department of Polymer Science and Technology (2004)
In this study, the High Density Polyethylene (HDPE) and Low Density Polyethylene (LDPE) blends prepared by Plasticorder Brabender were strengthened by adding Carbon Black (CB). Blends were prepared at 190 °C. Amounts of LDPE were changed to 30, 40, 50 and 60 percent by the volume and the percent amounts of CB were changed to 5, 10,15, 20 and 30 according to the total volume. Thermal and morphological properties were investigated by using Differential Scanning Calorimeter (DSC), Scanning Electron Microscope ...
Structural characterization of iron-based bulk metallic glass alloys produced by centrifugal casting
PEHLIVANOGLU, MK; Akdeniz, Mahmut Vedat; BOR, A Sakir (2003-05-01)
In this study bulk metallic glass alloys in the Fe-Zr-B-M (M=Al, Co, Cu, Mo, Ni, W) systemwere produced by using a centrifugal casting method. The thickness ofthe samples that could be produced with an almost completely amorphousstructure was found to be as high as similar to2 mm for alloy Fe60Co8Zr10Mo5W2B15. Alloying element additions or replacements have resulted in a considerable effect on glass-forming ability. Among others, Al and Cu were found to have the most deteriorative effects. The ternary alloy...
Structural and optical properties of thermally annealed thallium indium disulfide thin films
Guler, I; Hasanlı, Nızamı (Elsevier BV, 2020-06-30)
Structural and optical properties of thallium indium disulfide (TlInS2) thin films, deposited by thermal evaporation technique and thermally annealed at different temperatures, were analyzed. Crystallite size, dislocation density and lattice strain of the thin films were found from X-ray diffraction experiments. The atomic compositions of the films were determined from energy dispersive spectroscopy analysis. Surface morphology of the films was analyzed using atomic force microscopy. From room temperature t...
