Abstract

One solution for increasing the thermal conductivity of thermoplastics is adding nanoparticles to the polymer. Various titanium dioxide particle types are tested, which differ in their surface area. Also the amount of TiO2 is varied between 0 wt-% and 20 wt-%, because a compromise is needed between increased thermal conductivity and reduced strength and rigidity caused by increasing the concentration of particles. Furthermore, the way of compounding and the influence of dispersant on the particle dispersion in the polymer matrix are examined. Inter alia it could be determined that an amount of 20 wt-% TiO2 in polyamide 6 leads to an increase of thermal conductivity of 26 %. It can be shown that polyamide 6-filaments with 5 wt-% TiO2 can be melt spun. The mechanical properties of these modified filaments are still high enough for further textile treatment.
