Nanocomposites composed of unsaturated polyester matrix and organically modified clay filler were prepared. After the synthesis, XRD patterns showed that the interlayer spacing expanded from 1.25 nm to 4.5 nm. The mechanical properties of the nanocomposites were determined and it was found that adding only 3 w/w % organically modified clay improved the flexural modulus of unsaturated polyester by 35%. From DSC diagrams, it was found that T-g values of the nanocomposites also increased with the clay content. It is concluded that partially exfoliated / intercalated nanocomposites were formed at relatively low clay contents.

Synthesis and mechanical properties of unsaturated polyester based nanocomposites Inceoglu, AB; Yılmazer, Ülkü (2003-03-01) Two classes of nanocomposites were synthesized using an unsaturated polyester resin as the matrix and sodium montmorillonite as well as an organically modified montmorillonite as the reinforcing agents. X-ray diffraction pattern of the composites showed that the interlayer spacing of the modified montmorillonite expanded from 1.25 nm. to 4.5 nm, indicating intercalation. Glass transition values of these composites increased from 72degreesC, in the unfilled unsaturated polyester, to 86degreesC in the composi...
Mechanical properties and surface energies of low density polyethylene poly(vinyl chloride) blends Akovali, G; Torun, TT; Bayramlı, Erdal; Erinc, HK (1998-03-01) 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 consid...
Poly(epsilon-caprolactone) composites containing gentamicin-loaded beta-tricalcium phosphate/gelatin microspheres as bone tissue supports Sezer, Umran Aydemir; Aksoy, Eda Ayse; Hasırcı, Vasıf Nejat; Hasırcı, Nesrin (2013-02-05) In this work, novel antibacterial composites were prepared by using poly(epsilon-caprolactone) (PCL) as the main matrix material, and gentamicin-loaded microspheres composed of beta-tricalcium phosphate (beta-TCP) and gelatin. The purpose is to use this biodegradable material as a support for bone tissue. This composite system is expected to enhance bone regeneration by the presence of beta-TCP and prevent a possible infection that might occur around the defected bone region by the release of gentamicin. Th...
Mechanical Properties of FeCoCrNi High Entropy Alloy (HEA) Produced from Industrial Raw Materials by Induction Melting Erdal, Anıl; Polat, Gökhan; Kalay, Yunus Eren (null; 2018-11-25) Equimolar FeCoCrNi high entropy alloy (HEA) was produced from industrial raw materials which were not pure and contain various impurity elements such as Al, Si and C by induction melting in order to investigate mechanical properties of the alloy. This alloy was casted into compressed steel mold that let us to produce mechanical test samples. XRD (X-Ray Diffraction) and SEM (Scanning Electron Microscopy) were used for structural characterization of the samples. Brinell hardness test was applied for mechanica...
Flame retardancy of polymer nanocomposites Işıtman, Nihat Ali; Kaynak, Cevdet; Department of Metallurgical and Materials Engineering (2012) This thesis is aimed to understand the role of nanofiller type, nanofiller dispersion, nanofiller geometry, and, presence of reinforcing fibers in flame retardancy of polymer nanocomposites. For this purpose, montmorillonite nanoclays, multi-walled carbon nanotubes, halloysite clay nanotubes and silica nanoparticles were used as nanofillers in polymeric matrices of poly (methyl methacrylate) (PMMA), high-impact polystyrene (HIPS), polylactide (PLA) and polyamide-6 (PA6) containing certain conventional flame...
