This paper reports the chemoenzymatic synthesis of an amylose‐grafted cellulose. A maltoheptaose was chemically introduced to the amine‐functionalized cellulose by reductive amination to produce the maltoheptaose‐grafted cellulose. Then, the phosphorylase‐catalyzed enzymatic polymerization of glucose 1‐phosphate from the graft‐chain ends on the cellulose derivative was performed, giving the amylose‐grafted cellulose. The obtained material is shown to form gels and films. The dry and wet cycles of the materials were repeated.
