title: Self-assembly of amylose-grafted carboxymethyl cellulose.
abstract: In this study, we performed the self-assembly of the amylose-grafted carboxymethyl cellulose sodium salt (NaCMC) for the formation of nanofiber films under aqueous conditions. The introduction of amylose graft chains was conducted by the chemoenzymatic approach including phosphorylase-catalyzed enzymatic polymerization. The product had the rigid NaCMC main chain, which further assembled leading to nanofibers by the formation of double helix between the long amylose graft chains in the intermolecular NaCMC chains of the products. The lengths of the fibers were depended on degrees of polymerization of amylose chains. The nanofiber films were constructed by drying the alkaline solutions of the amylose-grafted NaCMC. The lengths of the nanofibers strongly affected their arrangements in the films. The nanofibers were merged further by washing out alkali to produce the robust nanofiber films.
