Abstract

The influence of graphite on volume and surface resistivity as well as on some thermal properties of composites containing a polylactide matrix was studied. The graphite content was up to 50 wt. %. It was found that the volume and surface resistivity decreased with the increasing graphite content and the percolation threshold appeared at the level of the filler content of 30-40 wt. %. No essential influence of graphite on phase transition temperatures was observed. However, the phenomenon of cold crystallization appeared. The sample mass loss upon heating started at ca. 270 °C.
