Abstract Alkali lignin was processed by plasma and then used in modification of phenol formaldehyde resin in this study.
Chemical structural changes of lignin which was processed by plasma as well as bonding strength, tensile property, curing performance and thermal property of the prepared phenol formaldehyde resin which was modified by
the plasma processed lignin were analyzed. Results demonstrated that: (1) Alkali lignin was degraded after the
plasma processing. The original groups were destroyed, and the aromatic rings collected abundant free radicals
and oxygen-containing functional groups like hydroxyls, carbonyls, carboxyls and acyls were introduced into
increase the reaction activity of lignin… More >
