Abstract
Provided is a hetero-junction membrane including: a first layer comprising first nanoparticles of a first conductive type; and a second layer comprising second nanoparticles of a second conductive type, wherein the first layer and the second layer are joined to each other. The hetero-junction membrane has advantages in that actuating efficiency is much higher, the direction of actuating can be predicted and the manufacturing processes are simple compared to conventional bucky paper formed of a single layer.
