Abstract
In this work, cellulose nanofibers (CNF) were obtained from sugarcane bagasse (SC) without high-energy mechanical treatments, using TEMPO-mediated oxidation. Variable NaClO concentrations were used to impart electrostatic repulsion between surface charged groups thus facilitating fibril separation. CNFs with diameters in the 3-5 nm range were obtained by oxidation of SC pulp with NaClO at 25 and 50 mmol/g. After a 30 min -sonication step, these...
