Preparation of Sugarcane Bagasse-Derived Cellulose Nanofibers via Deep Eutectic Solvent and Chemical Oxidation

Article Preview

Abstract:

This study aims to utilize sugarcane bagasse, an agricultural by-product, for the production of cellulose nanofibers. The preparation process combines deep eutectic solvent (DES) treatment with chemical oxidation methods. The objective is to develop sugarcane bagasse cellulose nanofibers (SBCNFs) using a green approach that ensures high yield and low energy consumption. The resulting SBCNFs are incorporated into polylactic acid (PLA) to create environmentally friendly products with net-zero carbon potential, as well as biocomposites that exhibit high thermal resistance and mechanical strength, thereby increasing the product's added value. The results show that DES effectively removes lignin and hemicellulose from sugarcane bagasse. The fibers obtained through DES treatment were successfully oxidized via chemical methods, yielding nanofibers with diameters ranging from 18.9 to 26.7 nm. Furthermore, the heat deflection temperature (HDT), tensile strength, and impact strength of the SBCNF/PLA composites reached 116.7°C, 62.5 MPa, and 27.2 J/m, respectively.
