Supercritical impregnation of thymol in poly(lactic acid) filled with electrospun poly(vinyl alcohol)-cellulose nanocrystals nanofibers: Development an active food packaging material

The active nanocomposite obtained from the whole procedure shows a significant improvement of its mechanical and thermal properties and the incorporation of thymol is not significantly modified when it is compared to the impregnation response of nanofibers-free PLA. However, the release rate of thymol was significantly slower when PV/CNC nanofibers are incorporated in the polymer structure.
