Abstract

Cellulose nanocrystals (CNs) were produced from unbleached and bleached sugarcane bagasse pulps by classical H₂SO₄ hydrolysis of fiber and pith fractions of pressed culms. Both the raw materials and final products were characterized by Fourier transform infrared spectroscopy, scanning electron microscopy, thermogravimetric analysis, field emission gun scanning electron microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy. The advantages and disadvantages of using both unbleached and bleached pulps for the production of CNs were demonstrated and discussed.
