Cellulose Nanocrystals (CNC) is a class of nanomaterials derived from natural cellulose decomposition, with high crystallinity, high strength, excellent thermal stability and biodegradability. CNC crystallinity is one of its most significant properties, which gives CNC great potential in a variety of high-end applications. This article will deeply explore the high crystallinity characteristics of CNC, including its impact on mechanics, thermal and optical properties, and analyze in detail how this characteristic promotes the widespread application of CNC in composite materials, environmentally friendly packaging, drug delivery and other fields. 1. The crystallinity of nanocellulose crystals and their importance. The crystallinity is the ratio of the crystalline region to the non-crystalline region in cellulose molecules, which affects the mechanical strength, thermal stability, chemical durability and other properties of CNC. Generally speaking, the crystallinity of CNC is as high as 70%-90%, which is much higher than that of natural cellulose (junction).
