Synthesis and Characterization of Mango Wood Nanocellulose Fibers

Abstract

Agricultural biomasses are the prominent natural sources of cellulose currently available on the planet. When this was treated chemically, this acquire the properties such as toughness, good biocompatibility, and higher thermal stability. In this study, Nanocellulose was extracted from Mango wood (Mangifera indica) a largely available agricultural biomass. The cellulose was alkali-treated followed by bleaching to remove lignin and hemicellulose, pectins, and waxes. The green solvent i.e Ionic liquid (1-butyl-3-methylimidazolium chloride ([Bmim] Cl) was used to dissolve cellulose to yield Nanocellulose through sonication and centrifugation. The functional groups and significant conversion of cellulose to nanocellulose are confirmed by FT-IR spectra. The crystallinity of synthesized nanocellulose is illustrated by XRD. The surface architecture and size obtained are represented by SEM and TEM monographs. The TEM images show the synthesized nanocellulose has a dimension between 27.33 to 34.85 nm. The thermal stability of the obtained nanocellulose was evidenced using TGA/DTA. The thermal studies records that synthesized nanocellulose shows superior thermal stability up to 473.8°C. The efficient conversion of agricultural waste into value added material is achieved through a greener pathway.
