Abstract Lignin is a natural biopolymer with a complex three-dimensional network, commercially obtained from waste
liquid of paper pulp and bioethanol production, and could be a candidate for preparation of environment-friendly
bio-based polyphenol material. In the present work, the demethylated wheat straw alkali lignin (D-Lig), prepared
by demethylation of wheat straw alkali lignin (Lig) using an in-situ generated Lewis acid, was used to synthesize
bio-based phenol formaldehyde resin adhesive (D-LPF) applied in plywood. Effects of synthetic process’s factors,
including lignin substitution for phenol, NaOH concentration and molar ratio of formaldehyde to phenol, on the
bonding strength and… More >
