Melt-mixed thermoplastic polymer/carbon nanotube composites for thermoelectric applications

Pötschke P., Krause B., Luo J., Leibniz Institute of Polymer Research Dresden (IPF), DE

Thermoelectric generators (TEG), which can convert waste heat directly into electricity, are one type of promising energy harvesting devices. The thermoelectric (TE) effect (also called Seebeck effect) describes an electrical potential (voltage ∆U) induced by [...]

Rheological Characterization of Melt Compounded Polypropylene/clay nanocomposites

Abdel-Goad M., Kretzschmar B., Pötschke P., Al-maameri R., Heinrich G., Sultan Qaboos University, OM

Polypropylene/clay nanocomposites were prepared by using a two step melt compounding process on twin screw extruders. In order to enhance the exfoliation, time and degree of mixing were varied using different screw speeds and dosing [...]

Thermal and Electrical Characterization of Polypropylene/Carbon Nanotubes Nanocomposites

Pandis Ch., Logakis E., Chorianopoulos M., Spanoudaki A., Kyritsis A., Peoglos V., Pissis P., Micusík M., Krupa I., Omastová M., Pionteck J., Pötschke P., National Technical University of Athens (NTUA), GR

The influence of multi-walled carbon nanotube (MWCNT) content on electrical/dielectric and thermal properties of CNTs-reinforced polypropylene (PP) nanocomposites is studied. We focus on the investigation of electrical and dielectric properties in relation to percolation: ac [...]

Thermal and Electrical Properties of Polyamide/Multi-Walled Carbon Nanotubes Nanocomposites

Logakis E., Pandis Ch., Kanapitsas A., Peoglos V., Pissis P., Pionteck J., Pötschke P., Micusík M., Omastová M., National Technical University of Athens (NTUA), GR

In the present work we investigate the influence of multi-walled carbon nanotubes (MWCNTs) on the thermal and electrical properties of a polyamide 6 (PA6) matrix by differential scanning calorimetry (DSC) and dielectric relaxation spectroscopy (DRS) [...]
