Effects of condensation degrees of FPLs on their adhesion performances. Lignin adhesive preparation: 1:2 (w/w) lignin/water, pH 7; hot-pressing conditions: 170 C, 8 min, 1.5 MPa and a glue application level of 100 g m -2 . The dot-dashed line at 0.7 MPa in c , d marks the minimum industrial requirement for the adhesion strength. All sample preparation and testing procedures as well as data calculation are described in the Methods . All examined bonding strengths were found to be significantly (analysis of variance (ANOVA), P < 0.01) affected by the condensation degree (or hydrogenolysis monomer yields) of lignins (Extended Data Table 1 ). Error bars show the s.d. of measured bonding strengths with four repeats.
