Critical discussion on the thermal behavior of sulfated cellulose nanocrystals
Source abstract
Abstract
Cellulose nanocrystals (CNCs) have evolved from a laboratory curiosity to an industrial material manufactured at a scale of up to 1 ton/day. In order to maximize their use in various applications such as composites, it is critical to evaluate the influence of the surface chemistry on their thermal stability. The effect of temperature on native CNCs is heavily damaging to the material integrity, but the early stage temperature-catalyzed degradation process can be prevented by neutralization of the surface sulfate half-ester groups, either by organic or inorganic counterions. In addition, we studied the influence of the hydrolysis conditions on the CNCs’ resistance to elevated temperatures. The observations were carried out by thermogravimetric analysis (TGA). Finally, complementary work regarding color formation when CNCs are exposed to heat is presented.
