抄録

<p>Wet-spinning of pure and completely linear α-1,3-glucan, synthesized in vitro enzymatic polymerization from sucrose, was first processed using an ionic liquid (1-ethyl-3-methylimidazolium acetate, [Emim][OAc]). The preparing dope of α-1,3-glucan was extruded, drawn, and coagulated in water and ethanol bathes. The cross-section shape, porosity, and mechanical property of the regenerated fibers were controlled by the type of the coagulation bath. Moreover, the crystal structure of the fiber coagulated in water showed a hydrated form (polymorph II). On the other hand, that of the fiber coagulated in ethanol showed an anhydrous form (polymorph III), and it was transformed into the hydrated form by solvent substitution with water.</p>
