ORIGINAL ARTICLE

Abstract

The influence of metal powders on the rheological, thermal properties, and IR spectra of poly(lactic acid)/metal (PLA/metal) composites has been studied in this paper. It was found that loading of tungsten and lead powders into PLA results in the anomalous decrease in viscosity of composites. The melting point and decomposition temperature are decreased by 1.5–5.0 °C and 50–60 °C compared to those for neat PLA with filling.
