Epoxy chain extender compatibilized poly(lactic acid)/polyoxymethylene blends: Improved crystallization, enhanced heat resistance and toughness for three-dimensional printing.
Bio-based and biodegradable poly(lactic acid) (PLA) is severely limited in three-dimensional (3D) printing due to its inherent brittleness, poor heat resistance, and slow crystallization rate. In this study, PLA/polyoxymethylene (POM) composites were prepared via one-step melt blending with an epoxy-functionalized olig...
