| 摘要 |
The present invention relates to: a graphene oxide film, coated with bile acid or bile salt, which is physiochemically stable and has excellent mechanical strength, by forming a coating layer containing bile acid or bile salt on a graphene oxide; and a method for manufacturing the same. The graphene oxide film coated with bile acid or bile salt, according to the present invention, has a stable, stacked structure having a very high mechanical strength and is physiochemically stable even against external stimuli such as a reductant, ultraviolet rays and a pressurized gas, and thus the graphene oxide film coated with bile acid or bile salt can be applied to a display element, a semiconductor element, a separation film, a sensor, a fuel cell, a solar cell, a lithium secondary battery and the like. |
