Porous poly(lactic acid) and PLA‐nanocomposite structures

This article presents foaming behaviors and cellular structures of poly(lactic acid) (PLA)‐clay nanocomposite and respective neat PLA foams using CO 2 as a foaming agent. The effects of nanoclay and foaming conditions on the foam morphology and mechanical properties of neat (PLA) and PLA‐clay nanocomposites have been investigated by temperature modulated differential scanning calorimeter (TMDSC), X‐ray diffraction, scanning electron microscopy,...
