Characterization and morphology analysis of degradable poly(l-lactide) film in in-vitro gastric juice incubation

► PLLA film was fabricated using a hot melting process to a thickness of around 40-50 μm. ► Fabricated PLLA film contained amorphous and crystalline regions. ► Decomposition of the PLLA film began with surface erosion in human gastric juice. ► Gastric solution diffused into the swelling PLLA film for the next step of degradation.
