Polylactide (PLA) is the leading bioplastic in production volume. To overcome its heat resistance limitations a novel hierarchical strategy has been developed. In this unique approach DD-lactide is grafted onto various nanoparticles (including degradable fillers like nanocellulose and non-degradable like fumed silica) and then embedded in commercially available poly(LL-lactide). The resulting high temperature use materials are relatively brittle with low extension to break.To oversome this limitation, blending with renewable poly(butylene succinate) is conducted. The full property suite of these unique biobased nanocomposite blends incorporating stereocomplexation is reported on. It is shown that the materials are suitable for a wide variety of uses requiring degradability.
