3.2. Thermogravimetric analysis (TGA)
In order to investigate the thermal properties of the PLA and
PLA/MCC composites, thermogravimetric analysis (TGA) were performed. Fig. 2 shows the TGA (weight% vs. temperature ◦C) and DTG thermograms of pure PLA and PLA/MCC composites with
various MCC contents. The thermal degradation data of pure PLA
and PLA/MCC are tabulated in Table 1, using the temperatures
