Adding nanoparticles to textile and chemical fiber products can deodorize and sterilize. Although chemical fiber cloth is strong, it has annoying static phenomenon, which can be eliminated by adding a small amount of metal nanoparticles.

Step 2 eat

Using nano-materials, refrigerators can resist bacteria. Sterile tableware and aseptic food packaging products made of nano-materials have come out. By using nano-powder, wastewater can be completely turned into clean water, which fully meets the drinking standards. Nano food is delicious and healthy.

Step 3 be alive

The application of nanotechnology can improve the washability of wall coatings by 10 times. Self-cleaning glass and self-cleaning tiles can be made by coating nano-thin layers on the surfaces of glass and tiles without scrubbing at all. Building materials containing nanoparticles can also absorb ultraviolet rays harmful to human body.

Step 4: ok

Nanomaterials can improve the performance of vehicles. Nano-ceramics are expected to become ideal materials for engine parts such as automobiles, ships and airplanes, which can greatly improve the efficiency, working life and reliability of engines. Nanosatellites can provide drivers with traffic information at any time to help them drive safely.

Extended data

Nanotechnology is based on the microscopic research theory of physics and chemistry, and is the product of the combination of modern science (chaotic physics, quantum mechanics, mesoscopic physics and molecular biology) and modern technology (computer technology, microelectronics, scanning tunneling microscope technology and nuclear analysis technology).

The idea of nanotechnology can be traced back to the 1960s.

1959, richard feynman, a famous physicist and Nobel Prize winner, attended the annual meeting of american physical society in California Institute of Technology, and made a famous speech "There is still a huge space at the bottom", predicting that human beings can make smaller machines with small machines, and finally arrange the atoms one by one to make products according to human wishes. This is the earliest dream about nanotechnology.

The term "nanotechnology" was first put forward in 1974. Professor Taniguchi, a scientist in tokyo institute of technology, used it to describe precision machining for the first time in a scientific paper entitled "On the Basic Concepts of Nanotechnology".

German physicist Grader Bing and Swiss physicist heinrich rohrer created experimental conditions for studying nanotechnology. 198 1 year, they all invented the scanning tunneling microscope (STM) in IBM's laboratory in Zurich, Switzerland.

For the first time, scanning tunneling microscope enables human beings to observe the arrangement of single atoms on the surface of substances and the physical and chemical properties related to the surface electronic behavior in real time.
