Make a hole in the micro world

  Xinhua News Agency, Beijing, November 4 (Reporter Wen Jing, Dong Xue) "We develop mesh carbon material, 1 gram of surface area can reach 3000 square meters, 2 grams can be covered with a football field." Academician, Chinese Academy of Sciences, Chemistry, Fudan UniversityProfessor Zhao Dongyuan said.

  It is believed that the new direction of nano-science is investigated by international peers, leading research and development of international related fields … November 3, Zhao Dongyuan team is due to the creation of the creation and application of the ordered mesh polymer and carbon material. , Won the first prize of the 2020 National Natural Science Award.

Inserting a "unmanned area" in the mesh material, if you talk a sponge, coral and activated carbon, you must be unfamiliar. Their common feature is that there are a lot of holes in the body.

These holes mean a larger specific surface area, lower density, better permeability and adsorption … In the micro-world, the aperture material in 2 nm to 50 nm, has become a school competition since the birth. Hotspot frontier field. It has a wide range of features that have a wide range of applications in many industries such as energy, health, information, and environments.

  Previously, the relevant research of the international chemical community is limited to the inorganic mesh material that is easy to synthesize, and the other important composition of the material can achieve "pioneering", which has been a "unmanned area" that is very satisfactory. .

  After bold imagination and hard to study, the Zhao Dongyuan team realized the creation of an orderly mesh polymer and carbon material, and it was considered to be the "milestone" and "pioneer" in the field of mesh materials.

  In the past 20 years, the organic-organic self-assembling idea of ??Zhao Dongyuan team and the generated mesh polymer and carbon materials have been used and studied by more than 1,500 scientific research institutions in more than 60 countries and leads the international mesh material. Development of the field. "Trienterate the study truly used in the country.

"Based on this research, Zhao Dongyuan team division cooperates, continuous breakthrough to many ways such as materials, catalysis, and storage, has produced an important application results in energy conversion, electronic devices, biomedicine and other fields – the residue and Further catalytic cracking into light oil, Sinopec 560,000 ton plug-in operation of 3 years; printed circuit board made of mesh material, the insulation is nearly 50%, and thousands of tons per year have been achieved Production; the mesh catalyst synthesized by targeted drugs and asymmetric drugs has also been developed … innovation is from anchoring direction to the spiritual light "" others are doing inorganic, can we do organic? Since the principle, you can make it.

"20 years ago, it flashed in the issue of Zhao Dongyuan’s mind, became the beginning of all. Zhao Dongyuan called this idea as" the science of the head ".

At that time, he had just ended his post on the United States, returning to the country to enter Fudan University, and a heart is going to do his favorite research on the land of the motherland.

  Compared to the more susceptible inorganic mesoporous material, organic polymer and carbon material have advantages such as lightness, softness, easy processing, but its synthetic process is more difficult, difficult, complex complexity, and complex, domestic and foreign materials are helpless.

  Students, group teams, ideas, and do tests. Nearly 3 years have passed, and the record is a failure.

"Just like in a black box." But deep discipline accumulated and keen insights let Zhao Dongyuan are extremely firm. "Experimental science is to continue to explore, constantly try."

"The transfer occurs in a" cerebral hole ": can make the complex problem simplified, split the synthesis process, step by step? Follow this idea, the team starts from the ancient polymer of phenolic resin, open new A round of experiments.

  Zhao Dongyuan has now clearly remembers that in 2003, 上海闵行598水磨店 there was a sudden call in late night.

The phone is the excited voice of the student Gu Dong: form an orderly mesh! Once the scientific gate is open, it will pass a hundred. After successful synthesis of the order polymer and mesoporous carbon, the team continued to propose organic-organic self-assembly ideas, establish a systematic synthetic method, created a series of new orderly mesh polymers and carbon materials … more than ten years Come, the 19 new mesoporous materials created by the Zhao Dongyuan team, all named FDU (Fudan University). These new mesoporous materials have been carried out for thousands of ton production, providing experimental reagents at home and abroad, promoting the development of the industry. Orthodox research, he wants to be the "finished hole" 44 years old, the academician of 上海电话品茶90分钟两次 the Chinese Academy of Sciences, published the papers in the field of mesoporial materials and the world leader … Zhao Dongyuan looks very lightly with the honor and the aura, and when it comes to scientific research, The light is flashing. "Bold thinking, rigorous, sure. The charm of basic research is innovation, a good result is happy!" In the field of mesh material "bubble" for more than 30 years, his body and enthusiasm as yesterday. In the eyes of Zhao Dongyuan, the world is like a huge "finishing" laboratory. Once, accompany your child to Lego world to play, those beautiful and vivid assembly components, in the brain of Zhao Dongyuan, aroused the water: in the micro world, can it also build a hole with various functional primitives? As a result, he opened a new research direction. Zhao 上海sn水磨 Dongyuan said that basic research is most needed to invest and focus, but not necessarily sitting in the table, "When you really immerse, anything in daily life can become the inspiration for science." "I always look Going to anything is thinking ‘Can you make a hole? This has become an occupational disease. I really want to make all things to make a hole, give them more features! "Immersed in the imagination, Zhao Dongyuan’s tone excited. "I followed Teacher Zhao in 14 years, he has been with us to innovate.

"Team member, Professor Li Wei, said, said that they will continue to explore seawater power generation, mesh liquid materials, etc. It is a steam diesel. Or make a heat insulating material, thin painting, you can achieve summer insulation, winter insulation.
