Abstract

The invention relates to a graphene cellphone window substrate and belongs to the field of microelectronic packaging. The graphene cellphone window substrate is prepared through the following steps: dissolving oxidized graphene by use of absolute ethyl alcohol and diluted hydrochloric acid, hydrolyzing for 20 minutes, performing suction filtration, drying the obtained materials in a vacuum drying oven at 240 DEG C, grinding the dried materials into powder, dissolving the powder in deionized water, putting a SiC slice in the solution to react for 2 hours under an atmospheric pressure of 0.1GPa and at a temperature of 110 DEG C, putting the obtained materials into a microwave apparatus for reacting for 20 minutes, coating the SiC with 1 micron Al, putting the SiC slice into a precipitation system, introducing acetylene and hydrogen under the protection of argon, increasing the temperature to 500 DEG C, ending the reaction 2 hours later, waiting for the SiC slice to be cooled to a room temperature, polishing the SiC slice after hydrogen ions are injected to the surface of the SiC slice, and finally, repeatedly cleaning the polished region by use of deionized water.

Description

A kind of Graphene mobile phone window substrate slice

Technical field

The present invention relates to a kind of Graphene mobile phone window substrate slice, belong to microelectronics Packaging field.

Background technology

2004, successfully from graphite, isolate Graphene in an experiment, from then on Graphene is paid close attention to by physics, region of chemistry and the military.Graphene has excellent conductivity and mechanical performance, become " dark fund ", and it can be coated in some good processing performances such as the surface of solids, is widely used in the numerous areas such as electronics, communication, aviation-grade defence and military by people.Along with the progressively breakthrough of the difficult problems such as mass production, the commercial application of Graphene is accelerated gradually, based on having obtained great achievement in research at present.The present invention discloses a kind of Graphene mobile phone window substrate slice, can protect mobile phone window better, and itself have good stability and resistance to wear, and behaviour does simple in process of production, and raw materials for production are cheap.

Summary of the invention

The invention provides Graphene mobile phone window substrate slice, simple to operate, inexpensively, product itself has stronger resistance to wear and stability to price.

In order to reach above-mentioned purpose, the concrete technical scheme of employing is:

A kind of Graphene mobile phone window substrate slice

(1) take a certain amount of graphene oxide, add absolute ethyl alcohol and the dilute hydrochloric acid solution of 1:2, slowly stir, be hydrolyzed 20 minutes, suction filtration, puts into vacuum drying oven, with 240 DEG C of oven dry, and pulverize;

(2) powder is dissolved in deionized water, puts into SiC thin slice, at the air pressure of 0.1GPa, at 110 DEG C of temperature, react 2 hours, put into microwave instrument, 500W, react 20 minutes;

(3) SiC is plated the Al of 1 micron, put into settling system, pass into acetylene and hydrogen under the protection of argon gas, temperature rises to 500 DEG C, terminates reaction after 2 hours;

(4) waiting for that SiC sheet is cold goes to room temperature, after SiC sheet surface imp lantation hydrogen ion, and polishing, then polishing area deionized water is cleaned repeatedly, obtained Graphene mobile phone window substrate slice.

specific embodiments:

Take a certain amount of graphene oxide, add absolute ethyl alcohol and the dilute hydrochloric acid solution of 1:2, slow stirring, be hydrolyzed 20 minutes, suction filtration, put into vacuum drying oven, with 240 DEG C of oven dry, pulverize, powder is dissolved in deionized water, put into SiC thin slice, at the air pressure of 0.1GPa, at 110 DEG C of temperature, react 2 hours, put into microwave instrument, 500W, react 20 minutes, SiC is plated the Al of 1 micron, put into settling system, acetylene and hydrogen is passed under the protection of argon gas, temperature rises to 500 DEG C, reaction is terminated after 2 hours, waiting for that SiC sheet is cold goes to room temperature, after SiC sheet surface imp lantation hydrogen ion, polishing, again polishing area deionized water is cleaned repeatedly, obtained Graphene mobile phone window substrate slice.
