PEER-REVIEWED ARTICLE bioresources

Cationic polyacrylamide is used in the paper-making industry as a drainage and retention aid. When a cellulose fiber suspension is drained during paper-making, the colloidal contact between fibers initiates hydrogen bonding, leading to the formation of paper (Retulainen et al. 1998). Cellulose nanofibers have high
