preparation example Construction

[0051] Specifically, an amorphous carbon / nano - Preparation micron film network, comprising the steps of:

[0052] 1) on the substrate 1 prepared nano - network 2 microns, and put into a reaction chamber 11;

[0053] 2) the introduction of the carbon source 3, the growth of amorphous carbon on the substrate 1 to form the amorphous carbon / nano - micron network films.

[0054] More specifically, it is also provided for preparing amorphous carbon / admittance of a "transfer method" - micron film network, comprising the steps of:

[0055] 1) providing a first substrate, prepared on the first substrate satisfied - network microns, and into the cavity;

[0056] 2) providing a container having contained a carbon source, was prepared and placed in a sodium - a first substrate upstream network micron film; completely discharged air in the reaction chamber, under a protective reducing gas for the preparation of a nano - micron Network heating the film of the first substrate;

[0057] 3)...

Embodiment 1

[0091] Step 1: A high purity copper for later after electrochemical polishing, washed with deionized water remaining on the high-purity copper electrolytic solution, and washed 2-3 times in acetone, alcohol, deionized water, each 10 minutes, blown dry with nitrogen foil.

[0092] Step 2: The self-supporting carbon nanotube network film 2 spreads prepared by CVD on the first substrate 1, about 10nm film thickness of the carbon nanotube network embodiment of the present embodiment, a pore size of between 20nm-1000nm.

[0093] Step 3: the carbon nanotube film with a first substrate 1 upside down in a vessel containing the carbon 3 4, such as figure 1 Shown, and in which one end of a quartz tube. The present embodiment is a solid PMMA carbon powder preferably has a mass 20mg, quartz boat 4 container.

[0094] Step 4: Wash the reaction gas is introduced into the cavity until the cavity and clean air is excluded; as a cleaning gas is high purity argon gas 500sccm preferred embodiment of...

Embodiment 2

[0100] Step 1-2 consistent with the embodiment of Example 11-2;

[0101] Step 3: A first carbon nanotube film with the substrate 1 is placed in the zone 22, as figure 2 , The carbon source is placed in the heating zone 21. The present embodiment is a solid carbon powder naphthyl, preferably mass 20mg, carbon filled container quartz boat.

[0102] Step 4: Wash the reaction gas is introduced into the cavity until the cavity and clean air is excluded; as a cleaning gas is high purity argon gas 500sccm preferred embodiment of the present embodiment, the washing time was 10min.

[0103] Step 5: After cleaning, adjustment meter, warmed to 22 to the temperature region T1 in an atmosphere of hydrogen and argon. After the temperature was stabilized, the temperature of the heating zone 21 reaches T2, a hold time of t1. In this embodiment, the hydrogen flow rate of 30 sccm, an argon gas flow rate of 300sccm, T1 is 400 ℃, T2 was 300 ℃, t1 is 40min.

[0104] In step 6-7 and step 6-7 in Example...

Abstract

The invention provides an amorphous carbon / nano-micron network film and a preparation method thereof, belonging to the technical field of nanomaterials, comprising: amorphous carbon and a nano-micron network, and the amorphous carbon is filled in the nano-micron In the pores of the network to form a composite film without pores; the amorphous carbon is a two-dimensional amorphous carbon nano film composed of carbon atoms. The present invention provides a novel amorphous carbon / nano-micron network film, which fills the nano-micron network with amorphous carbon to form a non-porous two-dimensional composite film, which can prevent external substances such as water and oxygen from interacting with electrons. Oxidative corrosion on the surface of devices, metal coatings, etc., has more excellent protection properties than nano-micro networks.

Description

Technical field [0001] The present invention relates to the technical field of nanomaterials, in particular, it relates to an amorphous carbon / nano - Network micron film and preparation method. Background technique [0002] Charcoal is one of the earliest human exposure to the substance, since R.E.Smalley, H.W.Kroto and R.F.Curl found C 60 After the study of carbon nanomaterials have been kept in the ascendant state. Since then, carbon nanotubes, graphene have been found, it can be said, carbon nanomaterials, revolutionized material aspects, and greatly promoted the development of other disciplines. [0003] Amorphous carbon, a carbon allotrope one element properties between diamond and graphite which is often considered to be a transition state. For the amorphous nanoscale carbon film, its presence also large differences corresponding two-dimensional thickness of a single atomic layer graphene. Specifically, the carbon between the carbon atom and the amorphous carbon film is n...
