Summary:Attapulgite (ATT) is a naturally rigid reinforcing filler. In this present study, ATT was first purified, and varying amounts of purified ATT was added to polylactic acid (PLA) to modify PLA through a melt-blending technique. The objective was to determine how the content of ATT affected the characteristics of the ensuing PLA/ATT nanocomposites: morphology, mechanical and thermal properties. Filling PLA with ATT increased both the thermal and mechanical properties, but too much ATT was not beneficial as the effect was to decrease both properties. Energy dispersive spectroscopy indicated that the percentage of Si element increased with the amount of ATT, but more than 10 wt % ATT led to a poor ATT distribution in the nanocomposites.
