Nanocellulose solution based on iron(iii) sodium tartrate complexes

Abstract This research aims to efficiently convert biomass residues like wheat and rapeseed straw into potential cellulose-based nanomaterials using the iron( iii ) sodium tartrate solvent and assess their suitability for nanocellulose solutions based on the selected mechanical, physical, and optical properties of the paper. The nanocellulose solution from wheat straw achieved better general solvent properties. The burst index for kraft pulp was significantly increased from an initial 37.63 to 124.27 kPa after applying wheat nanocellulose solution, and to 121.03 kPa for rapeseed straw solution. Furthermore, the tensile index of the kraft pulp increases from 12.00 to 17.04 N m g −1 for the wheat solution and 14.39 N m g −1 for the rapeseed straw solution, which is comparable to industrial nanofibrils (14.04 N m g −1 ) and nanocrystals (15.88 N m g −1 ). This research confirms the potential of biomass residues as a valuable alternative raw material for producing a nanocellulose solution.
