In this study, antibacterial properties were induced in polyurethane (PU) films by the incorporation of Ag+-loaded zeolites as fillers. The mechanical and thermal properties of the prepared composites were also investigated. For this purpose, two different types of zeolite microparticles, high-silica zeolite beta crystals and low-silica zeolite A crystals, were synthesized. Ag+ was added by ion exchange, and these particles were incorporated into the PU prepolymer, which was prepared from its main components of toluene diisocyanate and polypropylene ethylene glycol (medical purity). Microbiological tests revealed that both types of composites, prepared by the addition of Ag+-containing zeolite beta or zeolite A to the PU matrix, had antibacterial properties. It was demonstrated for the first time that a high-silica zeolite (zeolite beta) and its composite film could be effectively employed as antibacterial materials. Furthermore, mechanical and thermal characterization of the composites showed that the zeolites enhanced the mechanical properties of the polymer and did not cause any deterioration in its thermal properties.

Preparation of BaxSr1-xTiO3 thin films by chemical solution deposition and their electrical characterization
Adem, Umut; Özenbaş, Ahmet Macit; Department of Metallurgical and Materials Engineering (2003)
In this study, barium strontium titanate (BST) thin films with different compositions (Ba0.9Sr0.1TiO3, Ba0.8Sr0.2TiO3, Ba0.7Sr0.3TiO3, Ba0.5Sr0.5TiO3) were produced by chemical solution deposition technique. BST solutions were prepared by dissolving barium acetate, strontium acetate and titanium isopropoxide in acetic acid and adding ethylene glycol as a chelating agent and stabilizer to this solution, at molar ratio of acetic acid/ethylene glycol, 3:1. The solution was then coated on Si and Pt//Ti/SiO2/Si ...
Isocyanate functionalization of nano-boehmite for the synthesis of polyurethane organic-inorganic hybrid materials
Eroğlu, Gülden; Gündüz, Güngör; Çolak, Üner; Department of Polymer Science and Technology (2011)
In this study, organic-inorganic hybrid materials were prepared from polyurethane and boehmite. It was achieved by polymerizing monomers in the presence of functional nano-particles of boehmite with cyanate groups. The produced polyurethane organic-inorganic hybrid materials with enhanced mechanical properties were used for coating applications. Plate-like boehmite nano-particles were produced by hydrothermal process from aluminum hydroxide which was first ground in a high energy ball-mill, and then, proces...
Preparation and characterization of zeolite beta-polyurethane composite membranes
Aksoy, Eda Ayse; Akata, Burcu; Bac, Nurcan; Hasırcı, Nesrin (2007-06-05)
Incorporation of zeolite into polyurethane (PU) membranes was investigated by using as-synthesized and calcined zeolite beta particles at two different loading contents (0.1 and 1 wt %). The chemical interaction between the zeolite beta crystals and PU was observed by ATR-FTIR spectroscopy. The SEM results suggested that the calcined zeolite beta crystals were more homogeneously dispersed in the composite membranes than the assynthesized zeolite beta crystals. DMA results demonstrated that all composite mem...
Synthesis and characterization of hyperbranched and air drying fatty acid based resins
Bat, Erhan; Gündüz, Güngör; Department of Chemical Engineering (2005)
There has been a considerable effort in the last years to decrease the amount of volatile organic compounds (VOCs) present in organic coatings. The risks to human health and environmental hazards associated with VOCs, governmental directives, and economic factors are the main driving forces behind this effort. One way of achieving less or no VOC containing coating systems is to produce low viscosity resins. Hyperbranched resins owing to their globular structure have low viscosities and are promising materia...
Production of epoxide functionalized boehmite nanoparticles and their use in epoxide nanocomposites
Coniku, Anisa; Gündüz, Güngör; Maviş, Bora; Department of Chemical Engineering (2012)
In the present study the effects of addition of organically functionalized boehmite nano-particles on the mechanical properties of epoxy polymers were analyzed. Nanosize platelets of boehmite powders were produced via a hydrothermal process from the raw material aluminum trihydroxide Al(OH)3 provided by a a chemical supplier, but which in future studies can be replaced by local resources of aluminum trihydroxide available in Seydişehir, Turkey. The ground aluminum trihydroxide particles were submitted to a ...
