Query: Synthesis and characterization of cotton fiber-based nanocellulose   Nanocellulose prepared from the natural material has a promising wide range
of opportunities to obtain the superior material properties towards various
end-products. In this research, commercially available natural cotton was
treated with aqueous sodium hydroxide solution to eliminate the hemicellulose
and lignin, then cellulose was collected. The collected cellulose was subjected
to acid hydrolysis using sulphuric acid to obtain nanocellulose. The prepared
nanocellulose was further characterized with the aid of Fourier transform
infrared spectroscopy, X-ray diffraction and Scanning Electron Microscopy to
elucidate the chemical structure, crystallinity and the morphology.
