The "king of new materials" mentioned in "Dream Pool Essays"! What exactly is graphene?

If you ask what new material is the hottest nowadays, the one that everyone mentions the most is definitely graphene. Graphene is only 1/200,000 of the thickness of a hair, but its strength is 200 times that of steel. It is the thinnest, lightest and strongest material known in the world.

What exactly is graphene?

What is graphene?

As early as in "Mengxi Bitan", it was recorded that "there is petroleum in Fu and Yan... It looks like pure lacquer, but burns like hemp, and the smoke is very thick, and the curtains turned black wherever the smoke touches." The general idea is that there is petroleum in the Yan'an area of ​​Shaanxi, which looks like paint and can burn like hemp. It produces thick smoke when burning, and the places where the smoke touches turn black.

The "ultrafine smoke" mentioned here contains nanocarbons such as graphene.

Graphene is a two-dimensional nanomaterial composed of carbon atoms arranged periodically in a six-membered ring structure. It is currently the thinnest but also the strongest material in the world. It has excellent optical, electrical, thermal and mechanical properties and is one of the most important strategic materials in the 21st century.

Why is graphene called the "king of new materials"?

Graphene is ultra-thin, ultra-light and ultra-strong, and has amazing mechanical, electrical, optical, thermal and acoustic properties. Therefore, it is known as the "king of new materials" and is widely considered to be one of the important materials in the future electronics, energy, biomedicine and other fields. **It can play an important role in many different industrial applications, including electronic equipment manufacturing, energy storage system design, biomedical technology, etc. Its industry "Road to King" has experienced a three-step jump in food.

1. The era of "minced meat noodles" - graphene is added in small amounts as a mysterious ingredient, quietly reshaping the material properties and injecting innovative flavors into traditional industries;

2. The symbiotic chapter of “scrambled eggs with tomatoes”: graphene is no longer hidden behind the scenes, but becomes the functional main body alongside a variety of materials;

2. The creation feast of "Sashimi Lobster" - graphene will become the most dazzling ingredient on the stage with its extraordinary value and subversive functions.

Functions and applications of graphene

In today's cutting-edge field of materials science, the essence of the graphene product technology system can be condensed into the core architecture of "a piece of raw material + two fibers + two membranes".

A versatile raw material

——Single-layer graphene, as a cornerstone, is leading the material innovation with its unique two-dimensional structure and excellent physical and chemical properties.

Two fibers

——Represents high-performance graphene-based carbon fibers and health-conscious protective fibers, and are widely used in various fields.

In the field of civil aviation , energy saving and weight reduction, and improved fuselage strength, safety and maneuverability;

In rail transit , it can be used in decorative parts and structural components to reduce energy consumption, reduce smoke toxicity, and ensure passenger safety;

In automobiles , we will strengthen lightweight production, reduce carbon emissions, and enhance component performance.

When used on yachts , it can make the hull slimmer, enhance reliability and impact resistance, resist acid and alkali corrosion, and extend the life of the hull.

In addition to its industrial applications, graphene is also used in daily necessities, such as nylon, polyester, and viscose, covering all categories, connecting the entire fiber, fabric, and terminal textile industry.

Two films

——Heat dissipation film and heat spreader film, which use the efficient thermal conductivity of graphene to achieve precise temperature control. They are indispensable key technologies for cooling precision electronic devices and balancing thermal energy in energy equipment.
