Phase separation when PLA is blended with other bioplastics
Problem Phenomenon
When PLA is blended with other biopolymers (PHA, PBS, etc.), phase separation occurs.
Cause Analysis
Different bioplastics are thermodynamically incompatible and macroscopic phase separation occurs.
Solution
Use reactive compatibilizers; optimize the blending conditions.
Key Takeaway
PLA blending needs to solve the compatibility problem.
