Thermal response of polystyrene/poly methyl methacrylate (PS/PMMA) polymeric blends

The phase behavior of polymeric materials is understood through glass transition temperature. It is a temperature boundary above which the polymeric material is soft and viscous, and becomes hard, brittle, and glassy below this temperature. In the present work, PS/PMMA immiscible polymer blend samples are studied at different compositional ranges. Thermal transport properties of PS/PMMA polymeric blends were measured , from room temperature to 120°C. Variation in thermal conductivity ...

Polymer encapsulated paraffin wax to be used as phase change material for energy storage

In this thesis study, the sensor was used to characterize polymer encapsulated paraffin waxes as phase change materials (PCM). The main purpose of this study was to determine the effect of the polystyrene (PS) and PS: wax microcapsules on the morphology and thermal, mechanical and conductivity properties of the polypropylene matrix. Post-melting, the PP microcapsules were extremely well dispersed within the matrix and there was a strong interaction between them ...


Effect of nano CdS dispersion on thermal conductivity of PS/PVC and PS/PMMA polymeric blend nanocomposites 

The goal of this study was to determine how adding CdS nanoparticles to two polymer blends (PS/PVC and PS/PMMA) affects their thermal conductivities. Also, the effect of increasing the wt% of both PVC and PMMA in their respective blends was investigated. The thermal conductivity of the samples was determined through a transient plane method. The thermal conductivity of both polymer blends increased with the addition of CdS nanoparticles. ...

Studies on the Preparation of Polystyrene Thermal Conductivity Composites

Through the use of thermally conductive fillers the thermal properties of polystyrene (PS) are improved significantly. The different fillers include: aluminum oxide (Al2O3), magnesium oxide (MgO), B-silicon carbide particles (B-SiCp),  and  B-silicon carbide whiskers (B-SiCw). The use of PS flakes resulted in higher thermal conductivities than the use of PS particles, and the use of  B-silicon carbide whiskers resulted in the most favorable thermal conductivity and resulted in a ...

Preparation and characterization of thermally conductive polystyrene/carbon nanotubes composites

Researchers in this study aimed to develop polymer composites with high thermal conductivity, using polystyrene (PS) and multi-walled carbon nanotubes (MWNTs). These composites were prepared by ultrasonic radiation, through a simple-solution-evaporation method. Poly(styrene-co-maleic anhydride) (PSMA), with a benzene group and experiencing a strong affinity for PS was used as a base, to allow the MWNTs to be dispersed within the composite (MWNT-g-SMA). Results determined that the addition of MWNTs ...
