Polyurethane (PU) films were prepared from liquefied cellulose, hemicelluloses and lignin in different proportions. The simplex-lattice design method was employed to investigate the effects of each component and their associated interactive effects on the properties of the liquefied products and the PU films. Thermal properties were studied by means of Dynamic Mechanical Analyzer (DMA) and Thermal Gravimetry Analyzer (TGA). Results showed that the contents of cellulose, hemicelluloses and lignin significantly affected the thermal properties of PU films. The results of DMA suggested that the addition of the liquefied materials increased the glass transition temperature (T-g) of polyurethane (PU) films but decreased both storage modulus (E') and loss modulus (E ''). TGA results indicated that the addition of the liquefied materials decreased the thermal stabilities of the PU films.

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...
Sol-Gel processing of organically modified ITO thin films and characterization of their optoelectronic and microstructural properties Kesim, Mehmet Tümerkan; Durucan, Caner; Department of Metallurgical and Materials Engineering (2012) Indium tin oxide (ITO) thin films were formed on glass substrates by sol-gel method. Coating sols were prepared using indium chloride tetrahydrate (InCl3•4H2O) and tin-chloride pentahydrate (SnCl4•5H2O) stabilized in organic solvents (acetylacetone and ethanol). First attempt was to synthesize ITO thin films using standard/unmodified coating sols. The effect of calcination treatment in air (300 – 600 °C) and number of coating layer(s) (1, 4, 7 or 10) on optoelectronic properties (electrical conductivity and...
Structural characteristics of thermally evaporated Cu0.5Ag0.5InSe2 thin films Gullu, H. H.; Parlak, Mehmet (2016-05-01) In this work, Cu0.5Ag0.5InSe2 (CAIS) thin film samples were prepared by thermal evaporation of Cu, Ag, InSe and Se evaporants sequentially on glass substrates. Following the deposition, annealing processes were applied at different temperatures. The as-grown and annealed CAIS samples were nearly stoichiometric in the detection limit of the compositional measurement. The x-ray diffraction (XRD) measurements revealed that they were in polycrystalline structure with a preferred orientation along the (112) dire...
POLYURETHANES - EFFECT OF CHEMICAL-COMPOSITION ON MECHANICAL-PROPERTIES AND OXYGEN PERMEABILITY ULUBAYRAM, K; Hasırcı, Nesrin (1992-01-01) A series of polyether urethane films with varying hard/soft segment ratio were synthesized using toluene-2,4-diisocyanate (TDI) and polypropylene glycol (PPG) in order to evaluate them as biomaterials. In order to obtain medical purity the polymerization reactions were carried out in bulk without using any other ingredients such as solvent, catalyst, u.v. absorber, etc. The effects of chemical composition and the presence of the chain extender on some properties were examined. For the samples with higher TD...
Properties and Phase Segregation of Crosslinked PCL-Based Polyurethanes Guney, Aysun; Hasırcı, Nesrin (2014-01-05) Polyurethane (PU) films were prepared from different types of poly(e-caprolactone) glycols and hexamethylene diisocyanate without using any other ingredients such as solvent, catalyst, or chain extender. Polymers were stabilized by crosslinking formed as allophanate and/or biuret linkages during the curing process. The effects of different components on the product properties such as chemical structure, microphase segregation, mechanical strength, thermo-mechanical, thermal properties, and surface hydrophil...
