Abstract

TRANSFERRING HEAT THERMAL PULSE THROUGH POLYMER MATERIALS

Klaudia Wiśniewska and Carles M. Rubio*

ABSTRACT

The aim of this work was to determine the influence of temperature on thermal properties of polymer materials, as well as investigate the heat flux transfer in semicrystalline and amorphous polymers. The method is based on American standard ASTM D5334:2008 using a dual needle sensor; which was adapted to these materials. The thermal conductivity was determined due to its accuracy and reliability in the used technique. The polymers studied were polyamide-6, polymethyl methacrylate and polyvinyl chloride. The obtained results indicated that thermal conductivity of investigated polymer increased when the temperature increased. Major factor which influence on heat transfer is the crystallinity of the sample. Semicrystalline polymers had higher value of thermal conductivity than the amorphous polymers, the reason was more efficient vibration of phonon in semicrystalline lattice. Other important factors which affected the thermal properties of polymers were dimension and orientation of sample.
