Abstract
The utility model discloses a kind of film, it comprises: graphene film layer, and is formed in the PEN thin layer of graphene film layer upper and lower surface.The film obtained by establishing PEN thin layer on graphene film layer, the pliability having possessed Graphene is good, the feature that rigidity is high, and the chemical stability simultaneously also utilizing PEN is good, and resistance to acids and bases etc. are all better than other polyester films.Not only establish PEN thin layer on the surface of graphene film layer, also well make use of PEN thin layer and there is good heat resistance, and barrier property, protect graphene film layer but also improve the performance of film integral.
Description
Technical field
The utility model relates to thin film materials art, particularly relates to a kind of film.
Background technology
Film is a kind of thin and soft transparent sheet.Generally be made up of plastics, rubber.Wherein polyester film comprises as optical thin film, laminated film, superconducting thin film, polyester film, nylon film, plastic sheeting etc.It is widely used in electronic apparatus, machinery, the industries such as printing.But, for the film used at present, as makrolon material (PC), though possessing high strength and coefficient of elasticity, but high impact strength, serviceability temperature scope its maximum weak point wide be that case hardness is low, resistance to marring is bad; Polymethyl methacrylate (PMMA), high optical transparency, good weatherability, case hardness are high, but its impact strength is low, processing difficulties; PETG (PET), combination property is more excellent, but PET film generally need be processed through stretch processes, flatness is wayward, and due to orientation knot biaxially oriented polyester film because the physical and mechanical properties of the excellence such as its high grade of transparency, high brightness, higher heat-resistant stability, preferably barrier property is more and more extensive in the application that tobacco bale shifts, top grade aluminizes market, but the requirement along with Downstream Market automaticity is more and more higher and the consideration of production cost, needs polyester film thickness more and more thinner.
Summary of the invention
In order to solve the problems of the prior art, the purpose of this utility model is to provide a kind of film.Its adhesion strength is good, tensile strength is high, and thickness is little.
For achieving the above object, the utility model adopts following design:
A kind of film, it comprises:
Graphene film layer and the PEN thin layer in graphene film layer upper and lower surface.
Preferably, the outer surface of PEN thin layer is also provided with metallic diaphragm.
Preferably, described metallic diaphragm is Ti, TiN or TiC rete.
Preferably, the thickness of described metallic diaphragm is 0.5 ~ 10 μm.
Preferably, described graphene film layer is single-layer graphene layer or multiple graphene layers.
The utility model adopts above design, its film establishing PEN thin layer to obtain on graphene film layer, the pliability having possessed Graphene is good, the feature that rigidity is high, the chemical stability simultaneously also utilizing PEN is good, and resistance to acids and bases etc. are all better than other polyester films.Not only establish PEN thin layer on the surface of graphene film layer, also well make use of PEN thin layer and there is good heat resistance, and barrier property, protect graphene film layer but also improve the performance of film integral.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model Films Example one;
Fig. 2 is the structural representation of the utility model Films Example two.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment one:
As described in Figure 1, a kind of film disclosed in the utility model, it comprises:
Graphene film layer 1; Be formed in PEN (PEN) thin layer 2 of graphene film layer 1 upper and lower surface.Described graphene film layer 1 is single-layer graphene layer.
Embodiment two:
As shown in Figure 2, with embodiment one unlike, wherein on the outer surface of PEN thin layer 2, be also provided with metallic diaphragm 3.Described metallic diaphragm 3 is Ti rete.The thickness of described metallic diaphragm 3 is 0.5 μm.Described graphene film layer 1 is multiple graphene layers.
Embodiment three:
With embodiment one unlike, wherein on the outer surface of PEN thin layer 2, be also provided with metallic diaphragm 3.Described metallic diaphragm 3 is TiN rete.The thickness of described metallic diaphragm 3 is 10 μm.Described graphene film layer 1 is single-layer graphene layer.
Film of the present utility model can adopt following methods to prepare: at Cu Grown Graphene (Graphene); Be about the thick PMMA of 10m at Graphene/Cu surface spin coating one deck, treat PMMA spontaneous curing about 30 minutes; Sample is placed in Fe (NO

4etc. solution surface, fallen by Cu substrate etching, PMMA-Graphene swims on liquid level; Up picked up by PMMA-Graphene from liquid level with silicon chip, placement is dried to be placed in drying box or low vacuum (10-2Torr) and Graphene is contacted with silicon chip better; With acetone soln, PMMA is dissolved, Graphene is transferred on target substrate PEN thin layer; Enclosing one deck PEN thin layer again with on the PEN film of Graphene, graphene film layer is between PEN thin layer.
Further, metallic diaphragm can be established in the outer surface spraying of the PEN thin layer of above-mentioned obtained film or plating.
Thin film disclosed in the utility model is good for the pliability of Graphene, and the feature that rigidity is high, the chemical stability simultaneously also utilizing PEN is good, and resistance to acids and bases etc. are all better than other polyester films.Not only establish PEN thin layer on the surface of graphene film layer, also well make use of PEN film and once there is good heat resistance, and barrier property, protect graphene film layer but also improve the performance of film integral.Can be widely used in and make ultra-thin video recording tape base and high-performance electric sub-element, and for every field such as the top grade packaging of precision instrument and defence product and shock resistance packagings.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
