Abstract Microfibrillated cellulose (MFC) is often added to polylactic acid (PLA) matrixes as a reinforcing filler to obtain
fully-biodegradable composites with improved mechanical properties. However, the incompatibility between
MFC and the PLA matrix limits the mechanical performance of MFC-reinforced PLA composites. In this paper,
DL-lactic acid-grafted-MFC (MFC-g-DL) was used to improve the compatibility with PLA. Reinforced composites
were prepared by melt extrusion and hot-cold pressing. The tensile strength of the PLA/MFC-g-DL composite
increased by 22.1% compared with that of PLA after adding 1% MFC-g-DL. Scanning electron microscopy
(SEM), differential scanning calorimetry (DSC), and dynamic thermomechanical analysis (DMA) were used to
