▎ 摘　　要

The effect of cellulose chains on the electronic properties of graphene oxide sheets has been studied using the density functional theory. The results show that graphene oxide sheets with insulating and semiconducting properties behave as semiconductors in the presence of cellulose chains. The large energy band gap of graphene oxide sheets decreases by increasing the number of adsorbed cellulose chains. The results provide a new insight into hybrid materials, with higher performance, to be used in emerging nanoelectronic devices.
