A Simple Regeneration Process Using a CO₂-Switchable-Polarity Solvent for Cellulose Hydrogels.

ABSTRACT: Cellulose is one of the main components of plant cell walls, abundant on earth, and can be acquired at a low cost. Furthermore, there has been increasing interest in its use in environmentally friendly, carbon-neutral, sustainable materials. It is expected that the applications of cellulose will expand with the development of a simple processing method. In this study, we dissolved cellulose in aqueous N-butyl-N-methylpyrrolidinium hydroxide solution ([C₄mpyr][OH]/H₂O) and investigated the cellulose regeneration process based on changes in solubility upon application of CO₂ gas. We investigated the effect of transformation of the anion chemical structure on cellulose solubility by flowing CO₂ gas into [C₄mpyr][OH]/H₂O and con
