Understanding the effect of lignin on the production process and characteristics of lignocellulose nanofibrils from Eucalyptus nitens
[EN] Cellulose, hemicellulose, and lignin are the main constituents of lignocellulose nanofibrils (LCNFs). The content and modification of lignin in the pulps affect the production process and characteristics of LCNFs, showing changes in their morphology, surface, rheological, and dielectric behavio...
