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.

the effect of blending lignin with polyethylene

The effect of blending lignin with polyethylene

Lignin is an amorphous natural polymeric material that is based on phenylpropane derivates. Lignin has many functions in wood, but its commercial utilisation is relatively low. In biomass lignin is present together with polysacharides in the amount 20–30% lignin to 60–80% polysacharides . Various properties of lignin designate it for different technical purposes.
