In view of the above thermogravimetric analysis, it was concluded that the produced CNCCr(NO3)3 product from cellulosic feedstock exhibits better thermal stability than sulfated CNCH2SO4, and it will be more suitable for the production of green bio-nanocomposites as the typical processing temperature for polymer synthesis (i.e., thermoplastics) is normally higher than 200 °C. In this sense, CNCCr(NO3)3 with more thermal stability than that of MCC and sulfated CNCH2SO4 provide better-reinforcing capability for different applications such as cosmetics, thermal sensitive papers, and disposable products, owing to the high elastic modulus of its crystal domains . Table 2 summarizes the values of Tmax for cellulose and its nanomaterials derived from different species and collected from the literature.
