Preparation of Macroporous Cellulose Beads through a Single-Step Non-Solvent Induced Phase Separation Method from a Cellulose Acetate Solution

Abstract Macroporous cellulose beads having a three-dimensionally interconnected porous structure have been economically prepared from a cellulose acetate solution in a single step at room temperature. The water absorbency and stiffness of the obtained macroporous beads could be controlled by changing the CA concentration.
