2.2. Preparation of PLA and PLA/MCC composite
A 10 wt% solution of PLA pellets in chloroform was prepared
by stirring the solution inside the water bath at 60 ◦C
for 2 h until the pellets were fully dissolved (Maria, Garcia,
& Lagaron, 2010). The PLA solution was immediately cast
on the clean glass plates and left for the solvent to evaporate
at ambient temperature for 48 h. The thickness of the
cast solution was approximately 100 m and noted as pure
PLA.
