Polipropilen plastik atıklarının katalitik parçalanması ile değerli kimyasallar ve sıvı yakıt üretimi

Modification of calcium carbonate surfaces in natural gas plasma for their use in polypropylene composite systems Öztürk, Serhat; Akovalı, Güneri; Department of Polymer Science and Technology (2006) In this study calcium carbonate (CaCO3) particles are surface modified by using plasma polymerized natural gas and effects of surface modification of CaCO3 filler on mechanical properties of CaCO3-PP composites are investigated. Different combination of plasma factors; RF power, natural gas flow rate, and plasma discharge durations, are investigated. Mechanical properties such as tensile strength and Young’s Modulus are measured by tensile testing machine. Storage modulus and loss modulus measurements are d...
Modification of polypropylene films for antistatic and anti-scratch properties Kürkçü, Pınar; Bayramlı, Erdal; Department of Polymer Science and Technology (2007) Polypropylene films are widely used in industry, especially for packaging purposes. However, these films become statically charged when they are subject to friction. The accumulation of charges in some applications can be harmful, especially for the electronic devices and can cause undesirable appearance due to the attraction of dusts. Furthermore, minimum susceptibility to mechanically induced surface damage is a desired property since scratches reduce the mechanical strength and the bright texture of the ...
Production and characterization of polypropylene/organoclay nanocomposites Yayla, Saniye; Yılmazer, Ülkü; Department of Chemical Engineering (2007) Polypropylene, PP, based nanocomposites were produced via melt blending method by using twin-screw extrusion in this study. The effects of organoclay type, compatibilizer type, and mixing order of components on the morphology, thermal, mechanical and flow properties of ternary nanocomposites were investigated. Terpolymer of ethylene/butyl acrylate/maleic anhydride, ethylene/methyl acrylate/glycidyl methacrylate, and copolymer of ethylene/glycidyl methacrylate elastomers were used as compatibilizer, whereas ...
Synthesis and characterization of polypropylene based ion-exchange resin Ecevit, Safiye Tuba; Aras, Leyla; Tinçer, Teoman; Department of Polymer Science and Technology (2012) The synthesis of ion-exchange resin which can be used in various separation and chemical purposes, such as diffusion dialysis, electro dialysis, electrolysis and fuel cells has of considerable interest. For all these applications, the interactions of the ionic groups and the resulted morphologies are critical for establishing the unique properties. Considerable researches have been continued to understand the microstructure of these materials. The aim of this study is to synthesize polypropylene (PP) based ...
Synthesis of aluminum incorporated mesoporous catalysts for pyrolysis of polypropylene Obalı, Zeynep; Sezgi, Naime Aslı; Department of Chemical Engineering (2010) The total amount of plastic wastes produced by our society has been growing rapidly. The low biodegradability of these wastes creates a serious environmental problem that is directing the governments and environmental agencies to take serious measures to solve the problem of the plastic wastes. Landfilling or incineration of these wastes are not the right solutions, because the former has the danger of leaching and soil impregnation of its degradation products and the latter produce air pollution problems d...
