(A) The clarity situation of polymer blends of PLLA/PLGA and PCL/PLGA dissolved in THF with 10% (w/v) concentration at 60°C. The blend solution of PLLA/PLGA is clear, meaning the miscibility of PLLA and PLGA, while the blend solution of PCL/PLGA is turbid, indicating that PLGA is immiscible with PCL. (B) The SEM images of scaffold prepared from polymer blend of PLLA/PLGA.

Abbreviations: PCL, poly(ε-caprolactone); PLGA, poly(lactic-co-glycolic acid); PLLA, poly(l-lactic acid); SEM, scanning electron microscope; THF, tetrahydrofuran.
