TEMPO-Oxidized Cellulose with High Degree of Oxidation [PDF]

Polymers, 2017
In this paper, water-soluble 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO)-oxidized cellulose with a high degree of oxidation was prepared by a two-step process using bamboo dissolving pulp. The first step was to destroy the cellulose crystal I by NaOH/urea solution to obtain cellulose powder with decreased crystallinity.

The Oxidative Pretreatments of Cellulose for Cellulosic Superabsorbents

Journal of Anatolian Environmental and Animal Sciences, 2019
Cellulosic superabsorbents (SAP) are produced by using cellulose and cellulose derivative blends with different binding methods, generally.  But cellulose in SAP leads decrease in water absorption and water bonding ability because of nonreactive character of cellulose based on its chemical structure.
