Electrospinning of polystyrene/butly rubber blends : a parametric study
Göktaş, Ahmet; Gündüz, Güngör; Department of Chemical Engineering (2008)
Nanofibers, which have high surface area to volume ratio and better mechanical properties, are nanomaterials that both industry and scientists have started to show great attention in the last two decades. They are used in many areas such as life and filtration sciences, sensors, and composite reinforcement etc. Among five main production types, electrospinning is the best candidate for further development with a wide range of opportunities to be applied to all types of polymers and ceramics. This method use...
Synthesis and characterization of polystyrene clay nanocomposites
Özden, Gülsüm; Yılmazer, Ülkü; Department of Chemical Engineering (2004)
This study was undertaken to prepare polystyrene (PS)/montmorillonite (MMT) nanocomposites by different methods, including melt intercalation, in-situ polymerization and masterbatch methods. The in-situ polymerization method consisted of dispersing the styrene monomer into the galleries of MMT followed by subsequent polymerization. The PS/MMT nanocomposites formed by melt intercalation method were prepared on a twin-screw extruder. The masterbatch method was in fact a two-step process. As the first step, a ...
Sulfonation degree determination by adiabatic bomb calorimetry of polystyrene ionomers
Dumanlı, Ahu Gümrah; Aras, Leyla; Kısakürek, Duygu; Department of Polymer Science and Technology (2003)
In this study, the sulfonation degree of sulfonated polystyrene is determined by adiabatic bomb calorimeter, which is a novel analysis method for this determination. The theoretical combustion enthalpy calculations are compared with the experimental results and a correlation factor is found between these values. The effect of neutralization on the calorific values is also examined. The sulfonation reaction and the degree of sulfonation are determined by analytical titration method and elemental sulfur analy...

Nanocomposites based on blends of polystyrene
Dike, Ali Sinan; Yılmazer, Ülkü; Department of Polymer Science and Technology (2011)
Due to brittleness of polystyrene, PS, its usage area is restricted. To solve this problem and expand the usage area of PS, it can be blended and impact modified with an elastomeric material. In this study, the decrease in the modulus and tensile strength imparted by impact modification was overcome by reinforcing this mixture by incorporating organoclays and producing nanocomposites. This study consists of two parts. In the first part of this study three different types of aliphatic elastomeric materials a...
