PVA/(ligno)nanocellulose biocomposite films. Effect
This fact indicates that the increase in antioxidant power derives from the residual lignin content in nanocellulose due to the aromatic structure of lignin which acts as antioxidant agent preventing or retarding oxidation processes induced by oxidizing species, such as free radicals . The AOP of the films was increased from 4.76 ± 0.25% of neat PVA to 10.75 ± 1.37% and 10.01 ± 1.12% for LCNF-Mec and LCNF-TO, respectively.
