The crystallization and thermal behaviors of the modified-PLA were evaluated from −70 to 200 ◦C by using a Differential Scanning
Calorimeter (DSC) (materials analysis and characterizations, MTC
1000s) at the heating rate of 10 ◦C/min to observe the glass transition
temperature (Tg), melting temperature (Tm), crystallization
temperature (Tc) and the degree of crystallinity (Xc) of the modified
PLA was determined as shown in Eq. (1)
