Abstract: Methods for integrating the production of cellulose nanocrystals (CNC) and cellulose nanofibrils (CNF) from cellulose are provided. The methods use milder acid hydrolysis conditions than those for maximal CNC production to achieve reduced degradation of cellulose into soluble sugars. Also provided are negatively charged cellulosic solid residues (CSRs) in the form of cellulose fibers (CF) and/or cellulose microfibrils (CMF) during the acid hydrolysis, as well as CNFs fabricated from the CSRs.

Keywords: cellulose nanocrystals, cellulose nanofibrils, degradation, acid hydrolysis
