it
It's a bit "mysterious"
The nickname is "black gold"
But "low-key" to "almost transparent"
it
Very "powerful"
Superior performance and wide range of applications
It has the title of "King of New Materials".
it
It's quite "young"
It was first separated in 2004
Until now
Just 20 years
it
is an "Internet celebrity"
Once "Launched"
It comes with its own topic attributes
It is
Graphene
Loading...
"Graphene down jackets are warmer?"
"Can graphene batteries dramatically reduce charging time?"
"Can graphene be used in mobile phone manufacturing?"
……
Relevant information and product advertisements on the web
It's dazzling
Why is graphene so "hot"?
Let's take a look
1
Is "black gold" black?
Speaking of graphene
Maybe you don't know very well
But you know for sure its "mother"
- Graphite
Graphene, known as "black gold".
Is it black?
NO, NO, NO, NO,
Single-layer graphene in
Transmittance of 97.7% in the visible and near-infrared bands
The color is not easily visible to the naked eye
It can be described as "low-key" to "almost transparent"
2
Super strong, super flexible is it!
Graphene has:
Ultra-thin, ultra-strong, ultra-flexible
High electrical conductivity, high thermal conductivity, etc
Superior performance
The thickness of a single layer of graphene
Only 0.335 nanometers
Equivalent to the diameter of a human hair
One in 200,000
But its theoretical strength is 200 times that of steel
Graphene is also extremely easy to bend and fold
In flexible wearable devices
It has extremely high application value
There is no little graphene by it\
Shocked?
3
It can be "planted"!
After purification and processing
Graphene can be obtained from graphite ore
But there are structural flaws
and impurities, uncontrollable layers and other shortcomings
But
Now it only takes 10 to 30 minutes
Researchers use physical and chemical means
It can be "planted" on the copper foil
A sheet of A3 paper-sized high-purity graphene film
and then through technology transfer
Peel off the growing copper foil
You know, transfer the film intact
But it requires a lot of technology
There is also a new material
- "Super Mask Material"
It can be grown directly on the material you want to attach to
In aerospace, new energy and other fields
It has broad application prospects
4
"Show your talents" in many fields!
Due to its "magical" properties
Graphene is used in new energy, industrial energy saving,
aerospace, electronic information and other fields
can "show their talents"
Graphene is a super "panacea" for improving performance
Can stack "Buffs" on other products.
For example, after the addition of graphene to domestic aviation tires
Wear resistance and other properties are expected to be increased by about 20%.
Flexible batteries use graphene
The product can reach 100,000 bends
After growing a layer of graphene on the glass
Defogging and de-icing of automobiles in winter can have a good effect
With graphene
Subway seats can also be "warm"
A few days ago, it was equipped with a glass fiber material of monene
Subway seat heating unit
In Beijing CRRC Changxin Erqi Rail Equipment Co., Ltd
Loading successful
The seat surface temperature can quickly rise to 40°C
Achieve energy saving of 20~30% in electric seats
5
The road of discovery continues......
Beijing Graphene Research Institute
It is engaged in the research and development and application of graphene
New R&D institutions
After several years of hard work
Open up the collaborative innovation chain of industry, university and research
Developed and launched a series
Advanced graphene materials and equipment products
"Young" graphene
From materials research to laboratory results
and then to the landing of the production area
This road is "a long way to go"
The use of graphene "killer grade".
Still exploring
Continental in the field of graphene preparation and application
Constant acquisition breakthrough
Graphene is considered a revolutionary material of the future
It also allows people to expand its application
Full of imagination
Tough
The possibilities are endless
No wonder graphene has been "coming out" for 20 years
It's been so "hot" all the time
future
It is hoped that graphene will continue to "fire".
More surprises for us
Let's look forward to it!
