Abstract

In this work, the main chemical reactions conditions of a succession of specific chemical treatments used for the isolation of nanocellulose from sisal fibers were evaluated. The novelty of this work is the study done to analyze the effect of different reaction conditions (time or concentration) in fiber structure and composition as well as in the characteristics of obtained cellulosic samples. In order to achieve this goal different physicochemical, thermal and morphological characterization techniques were used after each chemical treatment and the most suitable reaction conditions were selected for the subsequent treatment. Moreover, the thermal stability evolution of cellulose nanocrystals during the dialysis process was evaluated.
