1. Introduction Nanocellulose is a type of nano-scale material obtained by physical, chemical or enzymatic treatment of natural cellulose. It has high strength, high specific surface area, biocompatibility and renewability. It is widely used in cutting-edge fields such as electronic materials, biomedicine, and environmental governance. Among all preparation methods, the selective oxidation method catalyzed by TEMPO (2,2,6,6-tetramethylpiperidin-1-oxy) radical has become a research hotspot because of its mild oxidation conditions, strong structural controllability and good product stability. This method can selectively oxidize the C6-position primary alcohol hydroxyl group to be a carboxy group to achieve nano-scale fiber dissociation, which is the key route for the preparation of **TEMPO oxidized nano-cellulose (TOCNs)**. 2. Detailed explanation of the TEMPO oxidation mechanism TEMPO oxidation reaction is a mild free radical oxidation process, its essence is the conversion of primary hydroxyl groups to carboxyl groups.

1. Core advantages of nanocellulose thermal performance. As a revolutionary bio-based nanomaterial, nanocellulose is attracting widespread attention from the materials science community. Studies have shown that nanocellulose has an ultra-low thermal expansion coefficient of 0.1×10⁻⁶/K, which is only 1/120 of steel and 1/23 of aluminum alloy. This characteristic is due to its highly ordered crystal structure, cellulose Iβ-type crystal, the thermal expansion coefficient in the axial direction is -1.5×10⁻⁶/K, showing abnormal thermal shrinkage and cold expansion. In terms of thermal stability, nanocellulose performs equally well: initial decomposition temperature: 220-260℃ (depending on the source and treatment process) Maximum decomposition temperature: 300-350℃ Carbon residue rate (600℃): 15-30% Glass transition temperature: 150-200℃ (dry state) 2.
