A route to Uniaxially oriented ribbons of bacterial cellulose Nanocrystals based on Isomalt spun sacrificial template

Abstract

We have carried out orientation of bacterial cellulose nanocrystals (BCNC) by implementing a process based on mechanical shearing BCNC dispersed in a viscous temporary isomalt glass. After the orientation, the isomalt matrix was selectively solubilized to afford uniaxially highly oriented BCNC ribbons as demonstrated by SEM and X-Ray studies. The 2D WAXS determined Herman's order parameter reached 0.85.
