초록

영어
To widen the applications of cellulose beads, sulfonated cellulose beads were prepared by chemically modifying HwBKP fibers with sulfur trioxide pyridine complex (STP), dissolving in tetraethylammonium hydroxide (TEAOH)/urea solvent, and dropping into acetic acid solution. Herein, the effects of the added STP amount on the properties of sulfonated cellulose solution and cellulose beads were investigated. It was observed that the sulfonated cellulose beads exhibited anionic surface charge in a fairly wide pH range, and the degree of substitution of sulfonic acid groups and the zeta potential of the cellulose beads could be controlled by adjusting the amount of STP added. In addition, as the added STP amount increased, the crystallinity of cellulose decreased, the viscosity and surface tension of sulfonated cellulose/TEAOH/urea solution decreased, and the size of cellulose beads increased.
