ABSTRACT
This study aimed to investigate the impact of poly (ethylene glycol) (PEG) on the properties of nanocomposites consisting of polylactic acid (PLA) and 3-aminopropyltriethoxysilane-modified bacterial cellulose (MBC) nanofibers. Differential scanning calorimetry (DSC) studies indicated that the presence of PEG enhanced the chain mobility of PLA during crystallization, thereby enabling the MBC to act as efficient nucleation agents. Furthermore, DSC and X-ray diffraction (XRD) analyses provided evidence for the formation of two distinct crystal structures, namely α and α,’ as well as various spherulitic dimensions. Finally, the toughening of PLA was occurred by adding PEG to PLA and ternary nanocomposites.
