The basic reseach on the surface sulfonation of polypropylene (PP) is very important for design of surfaces for higher functionalization. For this purpose, liquid-phase sulfonation of polypropylene surfaces at various temperatures and different time periods was performed using concentrated sulphuric acid. The physical and chemical changes produced by the sulfonation on the polypropylene surfaces were determined by contact angle measurements, mechanical analysis, UV-Vis spectroscopy, differential scanning calorimetry (DSC) and scanning electron microscopy (SEM). Both surface polarity and wettability of PP films were improved by sulfonation at low temperatures for short time periods; however, sulfonation at longer times, or higher temperatures, caused degradation of PP films. All sulfonated film samples had lower yield stress and stress at break. (c) Koninklijke Brill NV, Leiden, 2008

Synthesis and characterization of surface sulfonated polypropylene films Ecevit, Safiye Tuba; Aras, Leyla; Department of Polymer Science and Technology (2004) The basic reseach on the surface sulfonation of the polypropylene is very important due to the surface design for higher functionalization. For this purpose, liquid-phase sulfonation of the polypropylene surfaces at various temperatures for different time periods were performed by concentrated sulphuric acid. The physical and chemical changes formed by the effect of the sulfonation on the polypropylene surfaces were determined by contact angle measurement, mechanical analysis, UV-Vis spectrometer, different...
Preparation and Characterization of Polypropylene/Serpentine Composites Tan, Semra; Tincer, İsmail Teoman (Wiley, 2011-07-15) Composites of serpentine and polypropylene (PP) were prepared by twin-screw extrusion. Serpentine was collected as rocks from the Ankara-Beynam region and ground into powder with an average particle size of about 3 mu m for composite production. Both as-received (rock) and powdered serpentine were characterized. A silane coupling agent (SCA), gamma-aminopropyl triethoxy silane, was used for the surface treatment of serpentine. Mechanical properties of the composites were measured in terms of impact strength...
Preparation and Characterization of Low Density Polyethylene/Ethylene Methyl Acrylate Glycidyl Methacrylate/Organoclay Nanocomposites Coskunses, Fatma Isik; Yılmazer, Ülkü (Wiley, 2011-06-05) The effects of organoclay type, compatibilizer, and the addition order of components during melt-blending process on the morphology and thermal, mechanical, and flow properties of ternary nanocomposites based on low-density polyethylene (LDPE) were investigated. As a compatibilizer, ethylene/methyl acrylate/glycidyl methacrylate (E-MA-GMA), as organoclays Cloisites (R) 15A, 25A, and 30B were used. All samples were prepared by a corotating twin screw extruder, followed by injection molding. The highest incre...
PREPARATION AND CHARACTERIZATION OF PERLITE-FILLED HIGH-DENSITY POLYETHYLENES .2. THERMAL AND FLOW PROPERTIES AKINOKTEM, G; TINCER, T (Wiley, 1994-11-21) Thermal and flow properties of perlite-filled high-density polyethylenes (HDPE), studied in the first part of the paper, are discussed. Maximum peak temperatures of endotherms (T-mp) and the corresponding relative peak heights were examined by differential scanning calorimetry (DSC). The data obtained from a Brabender torque rheometer were evaluated to find the melt viscosities at low shear rate during preparation of perlite-HDPE composites. The filler concentration, types of HDPEs, and the use of gamma-APS...
Characterization and Electrical Conductivity of Poly(ethylene glycol)/Polyacrylonitrile/Multiwalled Carbon Nanotube Composites Aqeel, Salem M.; Kucukyavuz, Zuhal (Wiley, 2011-01-05) Polymer blends based on poly(ethylene glycol), polyacrylonitrile, and multiwalled carbon nanotubes (MWNTs) were prepared by the solvent cast technique from the dispersion of the MWNTs in the concentration range 0-3.45 wt %. The interaction of the MWNTs with the polymer blend was confirmed by a Fourier transform infrared (FTIR) spectroscopy study. The thermal properties of the polymer blend with the MWNTs were carried out by means of differential scanning calorimetry (DSC). It was evident from DSC that the p...
