    Development And Characterization Of Polylactic Acid/ Porous Corn Starch – Inclusion Complex Blend Film Containing Thymol by Loong, Ye Heng

    Published 2021
    “…The aim of this research was to fabricate a polylactic acid/porous corn starch – inclusion complex blend film with thymol as the active compound via co – precipitation for the formation of inclusion complex and compression molding for film formation, to determine its effect on the mechanical, thermal, and water vapor barrier properties of polylactic acid. Based on the Fourier - transform infrared spectroscopy result, absorption peaks observed in PLA – inclusion complex film samples, which corresponded to C=O stretching (1749.44 cm-1), C-H bending (1452.40, 1381.03, and 1359.82 cm-1), C-O stretching (1267.23, 1182.36, 1128.36, and 1082.07 cm-1), CO-O stretching (1045.42 cm-1), were found to be identical with pure polylactic acid film, indicating a high miscibility between inclusion complex and polylactic acid film. …”
