Microstructure and barrier properties of reactive compatibilized PLA/PA11 blends investigated by positron annihilation lifetime spectroscopy

Poly(lactic acid)/polyamide11 (PLA/PA11) blends were prepared by reactive blending with multifunctional epoxy here oligomer as compatibilizer, and the compatibility of PLA and PA11 was improved.The compatibilization, toughness mechanisms, and rheological behavior of PLA/PA11 blends were studied.Positron annihilation lifetime spectroscopy (PALS) was
