SUPER-TOUGH CELLULOSE AEROGEL FIBER AS WELL AS PREPARATION METHOD AND USE THEREOF

原文（中国語）

A super-tough cellulose aerogel fiber, as well as its preparation method and applications are provided. Specifically, the method includes employing a wet spinning technique; preparing a molecular-level cellulose solution using a cellulose polymer as the raw material; using the molecular-level cellulose solution as the spinning solution, wherein during the spinning process, the cellulose polymer undergoes in-situ self-assembly and hydrogen bonding crosslinking to form a multi-level nanofiber structure, wherein the nanofiber structure is a continuous three-dimensional multi-level pore network structure. The super-tough cellulose aerogel fiber not only has excellent physical properties such as high strength and high toughness, but also possesses good adsorption and heat preservation performance due to a multi-level porous structure, so that the super-tough cellulose aerogel fiber can be applied to weaving and other technical fields, and is widely applied.
