Today, nanotechnology has quietly penetrated into all aspects of our daily life, such as clothing, food, housing, and transportation. By applying nanotechnology and nanomaterials, antibacterial refrigerators and antibacterial washing machines can be made. Now, sterile tableware, sterile playing cards, sterile gauze and other products using nanotechnology and nanomaterials have also been launched. If nanotechnology is used in food manufacturing, today, nanotechnology has quietly penetrated into all aspects of our daily life, such as clothing, food, housing, and transportation.
Application of nanotechnology and nanomaterials can be made into antibacterial refrigerators, antibacterial washing machines, etc. Now, sterile tableware, sterile playing cards, sterile gauze and other products using nanotechnology and nanomaterials have also been launched. If nanotechnology is used in food manufacturing, it can help us improve gastrointestinal absorption.
Nano is just a high-tech icy technology? Nano is out of reach for the common people? Nanotechnology is another hot spot that people pay attention to after the Internet and genes. What is Nano? A nanometer is a measure of geometric size, measuring just one billionth of a meter in length, roughly equal to the length of 45 atoms arranged together. Nanotechnology refers to the fabrication of objects no larger than a few hundred nanometers in volume, only as wide as a few dozen atoms packed together.
The rise of nanotechnology in my country
As a leader in emerging high-tech technologies, Dali Nano has conducted in-depth research on plastics, rubber, rubber-plastic composites, papermaking, paint coatings, medicine, cosmetics, textiles and other industries for nearly 30 years. At present, the products that have been successfully introduced to the market include PVC-specific functional nanomaterials, PP-specific functional nanomaterials, PE-specific functional nanomaterials, PPR-specific functional nanomaterials, rubber-specific functional nanomaterials, and rubber-plastic composite functions. There are more than 40 kinds of seven series including functional nanomaterials and ABS special functional nanomaterials. The advent of this real basic nanomaterial and its functional nanomaterials will promote the development of my country's strategic emerging industries, and reduce my country's plastics, rubber, rubber-plastic composites, papermaking, paint coatings, medicine, cosmetics, textiles and other fields. Production costs, improving product quality, and participating in international market competition provide a source of raw materials with international cutting-edge technologies.
As low-carbon, energy-saving, and circular economy become new economic development models, the seven series of basic nanomaterials and functional nanomaterials produced by Dali Nano Company will have a broader market prospect and huge market demand. Coatings, inks, paper and other industries reduce production costs, improve product quality, and participate in international market competition, providing raw material sources with cutting-edge technologies in the world. new material. It will definitely make a significant contribution to the implementation of the strategic economic development model of low carbon, energy saving, and circular economy in my country.
The application of nanotechnology in life
Nanotechnology has been successfully used in people's lives. "Clothing": adding nanoparticles to textile and chemical fiber products can deodorize and sterilize; "food": aseptic tableware and aseptic food packaging made of nanomaterials have been When it comes out, nano-food is full of color, fragrance, and health; "living": the surface of glass and ceramic tiles is coated with a nano-thin layer, which can be made into self-cleaning glass and self-cleaning ceramic tiles, without scrubbing at all. Building materials containing nanoparticles can also absorb ultraviolet rays that are harmful to the human body; "line": Nanomaterials can improve and improve the performance indicators of vehicles.
At the Beijing Science and Technology Week, around an exhibition area called "Eco Lodge", nano-products are changing the concept of many people. Dou Jianguo put a piece of glass into the solar film transmittance meter. As he moved the glass, he reminded, "Be optimistic about the changes in the data." Sure enough, as soon as his voice fell, the infrared data on the measuring instrument changed from 84% to 4%. "Half is ordinary glass, and half is coated with nanofilm." He explained the reason for the change. "The main purpose of thermal insulation is to isolate infrared rays. Generally, the thermal insulation effect of glass is not ideal; coating a layer of film containing high-performance nano-oxide as the main raw material on the glass surface not only does not affect the transparency of the coating, but also has a good thermal insulation effect. High light transmittance.”
As the business manager of **** Nanotechnology Company, Dou Jianguo stated the benefits of nano-coated glass in one sentence, "It can make the room warm in winter and cool in summer, three to nine degrees higher in winter and three to nine degrees lower in summer. "According to expert estimates, the energy loss of glass windows accounts for about 50% of the energy consumption of the entire building. Is it possible to achieve energy saving by slightly modifying the old glass? In the past few years, Advanced Nanotechnology has developed a new type of energy-saving glass - low-E coated glass. "In many household windows, the glass has poor thermal insulation effect, and the heat exchange between indoor and outdoor is little hindered, and the air conditioner often runs at full capacity." Dou Jianguo said, "This energy-saving glass is coated with a layer of nanometers on the surface of ordinary glass. materials, which can save energy by about 30%.”
"Solar cells can be flexible, just like fibers." At the entrance of the "Ecological Cabin", Peng Ming and Yu Xiao, graduate students of Peking University, explained to the visitors coming and going. In order to overcome the problems of traditional flat-panel solar cells in terms of application form and electrode cost, the research team of Professor Zou Dechun of Peking University took the lead in the world in 2008 to propose a flexible woven fiber solar cell that does not require transparent electrodes.
In the past few years, the research team has extended fiber photovoltaic technology to fiber energy storage devices and designed a new flexible fiber supercapacitor composed of three fibers. The higher photoelectric conversion efficiency of fiber solar cells is increased to 7%. "This flexible nanofiber-based photovoltaic cell is tubular and has the best photon collection capability." Peng Ming said, "Unlike flat-panel cells such as crystalline silicon, this cell is more portable and can be applied to smart fabrics. It can be worn on the body to power flexible sensors, portable electronic devices, etc."
In a word, the application prospect of nanotechnology is very broad, and the economic benefits are very huge. I believe that in the near future, after further extensive application of nanotechnology, it will bring another industrial revolution to mankind in the 21st century, and also create a number of employment opportunities.
