Entangled cellulose nanofibers produced from sugarcane bagasse via alkaline treatment, mild acid hydrolysis assisted with ultrasonication

Agriculture waste such as sugarcane bagasse (SCB) is composed mostly of cellulose, a very versatile natural biopolymer with well-established applications in many industries. The purpose this study was to use combination treatment methods which include alkaline and mild acid hydrolysis assisted ultrasonication extract cellulose nanofibers (CNFs) from bagasse. Initially, the SCB fibers were treated sodium hydroxide aqueous hydrogen peroxide, bleaching agent before subjected followed by at 70% amplitude defibrillate disperse fibers. focused on using sulfuric extracted SCB. FESEM images isolated CNFs exhibited diameter range 20–30 nm length up several micrometers. This observation suggests that combined are highly effective isolating plant biomass. Moreover, XRD analysis reveals presence peaks 2θ 15.2° 22°, indicating type I crystallinity 42%. Meanwhile, FTIR spectra prove individual CNF successfully due removal non-cellulosic constituents. result verifies amorphous portions lignin hemicellulose completely removed. long entangled network fibrils through ultrasonication. expected have high strength aspect ratio can be used reinforced material manufacturing nanocomposites.
