摘要：

To widen the applications, cationic cellulose beads were synthesized by adding glycidyltrimethylammonium chloride (GTAC) to cellulose fibers dissolved in a mixture of tetraethylammonium hydroxide and urea at room temperature for cationic modification, and dropping the cationic cellulose solution into an acetic acid solution. Herein, the effects of the added GTAC amount on the properties of cationic cellulose soultion and cellulose beads were investigated. It was observed that increasing the amount of GTAC increased the viscosity and surface tension of the cationically modified cellulose solution and increased the particle size of the cellulose beads. Furthermore, the zeta potential of the cellulose beads can be controlled by modifying the GTAC amount. © 2022 Korean Technical Assoc. of the Pulp and Paper Industry. All rights reserved.
