If nanotechnology is used in food manufacturing, it can help us improve gastrointestinal absorption.

Nano is just a highly sophisticated ice-cold technology? Nano is out of reach for the people? Nano technology is another hot topic that people are following after the Internet and genes. What is a nanometer? A nanometer is a unit of measurement of geometric dimensions. The length is only one part per billion of a meter, which is slightly equal to the length of 45 atoms arranged. Nanotechnology refers to the manufacture of objects with a volume not exceeding hundreds of nanometers, the width of which is only the width of dozens of atoms gathered together.

The rise of nanotechnology in my country

Dali Nano, as a leader in emerging high-tech technologies, has conducted in-depth research on industries such as plastics, rubber, rubber-plastic composites, papermaking, paints, pharmaceuticals, cosmetics, and textiles for nearly 30 years. At present, the products 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 forty kinds of seven series including sexual nanomaterials and ABS special functional nanomaterials. The advent of this truly basic nanomaterial and its functional nanomaterials will promote the development of China's strategic emerging industries and reduce the number of fields in China's plastics, rubber, rubber-plastic composites, papermaking, paints and coatings, medicine, cosmetics, textiles, etc. Production costs, improving product quality, and participating in international market competition provide a source of raw materials with the most cutting-edge technology in the world.

With low carbon, energy saving, environmental protection and circular economy becoming the new economic development model, the seven series of basic nanomaterials and functional nanomaterials produced by Dali Nano will have a broader market prospect and huge market demand. , Coatings, inks, paper and other industries reduce production costs, improve product quality, participate in international market competition and provide the source of raw materials with the most cutting-edge technology in the world, at the same time, provide the most cutting-edge technology for the consumption of China's petroleum, wood and other strategic resources Replace new materials. It will definitely make a significant contribution to China's strategic economic development model of low carbon, energy saving, environmental protection and circular economy.

Application of nanotechnology in life

Nanotechnology has been successfully used in people's lives. "Clothing": adding nanoparticles to textiles and chemical fiber products can eliminate odor and sterilization; "food": aseptic tableware made of nanomaterials, aseptic food packaging supplies The nano food is available in all colors and fragrances, and it is also healthy; "live": the surface of glass and tiles is coated with a thin layer of nano, which can be made into self-cleaning glass and self-cleaning tiles, without having to scrub at all. Building materials containing nanoparticles can also absorb ultraviolet rays that are harmful to the human body; "OK": Nanomaterials can improve and improve the performance indicators of vehicles.

At Beijing Science and Technology Week, around an exhibition area called "Ecological Cabin", nano-products are changing the concept of many people. Dou Jianguo put a piece of glass into the solar film transmittance measuring instrument. As he moved the glass, he reminded, "I'm optimistic about the changes in data." Sure enough, his voice just fell, and the infrared data on the meter changed from 84% to 4%. "Half is ordinary glass, half is coated with nano film." He explained the reason for the change. "The heat insulation is mainly infrared insulation. Generally, the heat insulation effect of glass is not ideal; coating a 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 good heat insulation effect High light transmittance. "

As the business manager of the first nanotechnology company, Dou Jianguo said the benefits of nano-coated glass in a 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." It is estimated that the energy loss of glass windows accounts for about 50% of the energy consumption of the entire building. Can energy saving be achieved through a slight modification of the old glass? In the past few years, the first nanotechnology company has developed a new type of energy-saving glass-low-e coated glass. "Many home windows have poor glass insulation, little hindrance between indoor and outdoor heat exchange, and air conditioners often run at full capacity." Dou Jianguo said, "This energy-saving glass is coated with a layer of nano on the surface of ordinary glass. Material, can save about 30% energy. "

"Solar cells can be flexible, just like fibers." Peng Ming and Yu Xiao, Peking University graduate students, explained to visitors coming and going at the door of "Ecological Hut". In order to overcome the difficulties of traditional flat solar cells in terms of application form and electrode cost, Professor Zou Dechun's research team at Peking University first proposed a flexible woven fiber solar cell without transparent electrodes in 2008.

In the past few years, the research team has expanded fiber photovoltaic technology to fiber energy storage devices and designed a new flexible fiber supercapacitor composed of three fibers. The maximum photoelectric conversion efficiency of fiber solar cells is increased to 7%. "This flexible nanofiber-based photovoltaic cell is tubular and has a full range of photon collection capabilities." Peng Ming said, "Unlike flat cells such as crystalline silicon, this cell is more portable and can be applied to smart fabrics. The body provides energy for flexible sensors, portable electronic devices, etc. "

In short, the application prospects of nanotechnology are very broad, and the economic benefits are huge. I believe that in the near future, nanotechnology will be widely used in the near future, and it will bring another industrial revolution to humans in the 21st century, and also create some employment opportunities.
