Agricultural biomasses are the prominent natural sources of
cellulose currently available on the planet. When this was treated chemically,
this acquires the properties such as toughness, good biocompatibility, and
higher thermal stability. The purpose of this study is to transform
agricultural biomass into value-added material through green synthesis, and
hence, the nanocellulose is synthesised from Mango wood. In this study,
Nanocellulose was extracted from Mango wood (Mangifera indica), a widely
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. FT-IR, X-Ray Diffraction, SEM, TEM, and Thermo Gravimetry
studies were used to examine the functionality, crystallinity, and morphology
of synthesised nanocellulose. The functional groups and significant conversion
of cellulose to nanocellulose are confirmed by FT-IR spectra. The crystallinity
of the synthesised nanocellulose is illustrated by XRD. The surface
architecture and size obtained are represented by SEM and TEM monographs. The
TEM images depict that the synthesised nanocellulose has a dimension between
27.33 and 34.85 nm. The thermal studies evidenced that the synthesised
nanocellulose shows superior thermal stability up to 473.8°C. As a result of
high thermal resistance, this can be used in the manufacture of
high-temperature-resistant materials. Due to their smaller size, these can be
used to manufacture high-strength nanocomposites. The efficient conversion of
agricultural waste into value-added material is achieved through a greener pathway.
This study demonstrates the practical application of nanocellulose synthesised
from agricultural biomass, providing a sustainable approach to solid waste
management and reducing chemical usage in nanocellulose production in India.
