nanomaterials
Do you know what nano is?
Nano (nm) is a unit of length. 1 nanometer is 10-9 meters (one billionth of a meter). For macroscopic substances, nanometer is a very small unit. For example, the diameter of a human hair is generally 7000- 8000nm, the diameter of human red blood cells is generally 3000-5000nm, the diameter of general viruses is also tens to hundreds of nanometers, and the grain size of metals is generally in the order of microns; for microscopic substances such as atoms, molecules, etc., it was previously expressed in angstroms , 1 angstrom is equivalent to the diameter of a hydrogen atom, and 1 nanometer is 10 angstroms.
It is generally believed that nanomaterials should include two basic conditions: first, the characteristic size of the material is between 1-100nm, and second, the material has some special physical and chemical properties that are different from conventional size materials.
Nanotechnology is an emerging technology that emerged in the 1990s. It is a brand-new technology that studies the movement patterns and characteristics of electrons, atoms and molecules in a space of 0.10 to 100 nanometers (one billionth of a meter).
Some novel nanomaterials have been applied to certain products, producing magical effects
"Green" energy
The energy crisis has caused humans to be looking for various efficient and "green" energy sources. New materials play an important role in this.
For example, traditional batteries pollute the environment and cannot be reused. Lithium-ion batteries made with lithium as electrodes are small in size, light in weight, can be charged multiple times, and have little environmental pollution. It has been widely used in mobile communications, small cameras and other equipment.
When artificial earth satellites are launched into the sky, the electronic instruments and equipment on satellites and spacecrafts require sufficient and continuous electrical energy, and are required to be light in weight, long in life, easy to use, and able to withstand the effects of various shocks and vibrations. Solar cells made of polycrystalline silicon and amorphous silicon materials fully meet these requirements
summary
1. A variety of high-tech materials provide convenience for our lives
2. Nanomaterials are the most mentioned among modern materials. Its uses are also very wide.
3. Memory alloy is playing an increasingly important role due to its own characteristics.
