Results of the TGA tests on neat PLA, neat PBAT and their blends.
| Sample | T5% (°C) | Tpeak1 (°C) | Tpeak2 (°C) | m700 (%) |
|---|---|---|---|---|
| PLA | 339.7 | 376.1 | - | 0.0 |
| PLA_PBAT_15 | 341.2 | 372.6 | - | 0.9 |
| PLA_PBAT_30 | 341.8 | 368.8 | 406.0 | 1.5 |
| PLA_PBAT_45 | 343.7 | 368.5 | 409.9 | 2.6 |
| PLA_PBAT_60 | 345.3 | 360.0 | 409.4 | 3.4 |
| PLA_PBAT_75 | 346.5 | 366.4 | 412.6 | 3.8 |
| PBAT | 374.3 | - | 414.4 | 4.2 |
T5% = temperature corresponding to a mass loss of 5%; Tpeak1 = temperature of the maximum degradation rate of PLA; Tpeak2 = temperature of the maximum degradation rate of PBAT; m700 = mass residue at 700 °C.
