Description
Technical field
The utility model belongs to the grapheme material technical field, relates in particular to a kind of Graphene/graphene oxide composite membrane.
Background technology
The appearance of CNT and Graphene has stimulated people its physics and mechanical property to be applied to the very big interest of device.Confirmed that in theory and experimentally they have very high hardness and intensity.Also have very high electrical conductivity and thermal conductivity in addition.Unique mechanical and physical property make them obtain extensive studies in device miscellaneous.
Many research groups are obtaining remarkable achievement aspect the microactrator of CNT, but the research based on the microactrator of full grapheme material and sensor aspect is less relatively, Small 2009,6,210 have introduced a kind of material that comprises CNT/graphene oxide composite membrane, and this material demonstrates good humiture sensitivity.But carbon nanotube layer is made up of nano-material, and the graphene oxide layer is made up of the nano flake material, thereby the associativity of two layers of material is poor, and electrical conductivity is not high.
The utility model content
Goal of the invention:Shortcoming for the associativity difference that solves the two layers of material that prior art exists the purpose of this invention is to provide a kind of Graphene/graphene oxide composite membrane, because two layers of material is graphene-based material, the composite membrane associativity of preparation is good.
Technical scheme:A kind of Graphene/graphene oxide composite membrane is composited by graphene layer and graphene oxide layer, and every layer thickness is between 50 nanometers-1 millimeter.
Beneficial effect:Compared with prior art, the present invention has following characteristics:
The present invention utilizes suction filtration or evaporation to obtain the composite membrane of Graphene/graphene oxide, and this film has good mechanical performance, simultaneously has very strong response characteristic for temperature or humidity, and the crimp force that causes owing to high temperature or high humility is quite big; The amount of crimp that different temperature or humidity cause is also different big.When temperature or humidity reduction, the flattening gradually of this film has good repeatability in addition.This characteristic makes Graphene can be applied on microactrator or the sensor.
