文摘
- •
In situ microfibrillation of PLA/PA blends was used to produce fully bio-based films.
- •
Flexible PA microfibrils were successfully produced and dispersed in PLA matrix.
- •
Physical gelation even at low contents of microfibrils improved PLA’s melt strength.
- •
The microfibrils greatly improved the PLA’s crystallization behavior.
- •
Oxygen and water vapor transmission rates of the PLA film were reduced significantly.
