Not long ago, Ren Zhengfei in an interview that will be a technological revolution broke out in 10 to 20 years, "I think the future greatest subversion of this era is the era of graphene subversion silicon era", "now there is a limit width of the silicon chip, the limit is seven nm, has been near the border, graphite is the frontier technology revolution". Where is the graphene mentioned here? Can it really bring about subversion?


Shi Moxi (Graphene) is a two-dimensional carbon material, is a single layer graphene, double layer graphene and multilayer graphene collectively. Published in 2004, Andre, Professor of discovery at the University of Manchester, won the Nobel prize for physics in 2010.
On March 2015, Chinese Academy of Sciences Chongqing Green Intelligent Technology Research Institute and the Ningbo material technology and engineering Chinese Institute launched a graphene mobile phone, the mobile phone uses a newly developed graphene touch screen, battery and thermal film, touch, longer standby time has better and better thermal conductivity performance.


Carbon nanotubes
Carbon nanotubes (CNTS) also called buckytubes, is a kind of new material with special structure and properties. Carbon nanotubes are considered as important materials for theoretical research and application because of their peculiar physical properties. At present, the research on the characteristics and production methods of carbon nanotubes has made great progress, and the research focus is turning to mass production and application fields.


Sapphire
First of all, sapphire is a kind of precious stone. It exists in nature in different forms and colors. Red sapphires are often referred to as "rubies", and blue sapphires are usually processed into jewelry. But some sapphires are transparent, so they can be used on smartphones.
What's so special about sapphires? Sapphire is currently one of the most hardest substance on earth, Moore its hardness value is 9 (mol hardness value of up to 10), second only to diamond hardness (10), which means that only with the same hardness of diamonds material to hurt and to sapphire. So unless you have a diamond in your pocket, the sapphire screen phone in your pocket will not be scratched for months.
Apple Corp has been applying sapphire glass technology on iPhone products, such as iPhone 5S's Home key, camera glass, etc., while the newly launched smart watch iWatch also uses a sapphire screen.


Optically thin
A class of optical dielectric material consisting of thin layered media propagating beams through an interface. The application of optical films began in 1930s. In modern times, optical thin films have been widely used in the field of Optics and optoelectronics, producing various optical instruments.
The main optical thin film devices include reflecting film, antireflection film, polarizing film, interference filter and spectroscope, etc..


Rare earth material
Rare earth elements were first found in relatively rare minerals produced in Sweden. "Soil" is called "insoluble" substances at the time, so it is called "rare earth". Rare earth materials called rare earth materials.


Carbon fiber material
Carbon fiber (carbon fiber, referred to as CF) is a new kind of fiber material with high strength and high modulus fiber with carbon content of more than 95%. It is a flaky graphite, microcrystalline and other organic fibers stacked along the axial direction of the fiber, obtained by carbonization and graphitization of microcrystalline graphite material. Carbon fiber "an hand in a velvet glove lighter than aluminum," the quality, but the strength is higher than that of steel, and has the characteristics of corrosion resistance, high modulus, in the national defense and civilian areas are important materials. It has not only the intrinsic characteristics of carbon materials, but also the softness and processability of textile fibers. It is a new generation of reinforced fiber.


Nanofiber material
The use of nano fiber is very wide, such as the implantation of nano fiber fabric surface, forming a layer of stable gas film, made biphobic interface fabric, can waterproof, anti oil, anti fouling and high protection; made of nano fiber, the fabric and porous membrane, can not only make the through the air, with the breath, but also wind and filtering fine particles, a barrier of aerosol, anti chemical and biological weapons and toxic substances. In addition, nano fiber can also be used in chemical, pharmaceutical and other products purification, filtration and so on.


polyimide material
Polyimide is one of the best comprehensive performance of organic polymer materials, high temperature above 400 degrees, long-term use temperature range of -200 to 300 DEG C, no obvious melting point, high insulation resistance, dielectric constant of 4 103 GHz, the dielectric loss is only 0.004 ~ 0.007, F to H grade insulation material.
