"Because of the irregular school curriculum, two years of high school life is like a waste." After completing two years of study in Tangxia Middle School, Dai Liming failed the college entrance examination. However, he was not discouraged and still chose to continue his studies. 1978, attend the advanced class of Ruian Middle School and study hard. Driven by a good learning atmosphere, he rekindled the fire of hope.
A mid-term exam, because something happened at home, he could not take the math exam. Mr. Huang Jiguang, the math teacher, asked him to take the exam back and let him finish it at home like an exam. The teacher's trust increased Dai Liming's confidence. At the same time, under the guidance of chemistry teacher Cao Zhendan, the difficult chemistry test in the college entrance examination was like a roadblock, which shattered many people's dreams of the college entrance examination, while Dai Liming got Ryan's second highest score. From 65438 to 0979, he was admitted to the Department of Chemical Engineering of Zhejiang University with excellent results. As the university is approaching graduation, Dai Liming is busy writing his graduation thesis. At that time, influenced by Yuan Huigen, a mentor who returned from studying in the United States, Dai Liming chose a new plastic variety-"high impact polystyrene", which has not been deeply studied in China. From topic selection to completion, it took two months to study a plastic entity. After the completion of this graduation thesis, Yuan Huigen, the tutor, found that there were still many places to dig deep, so he instructed Dai Liming to do in-depth research and made a related paper, which was published in domestic chemical professional magazines.
"The general impact strength of polyethylene is not very good. If you add some rubber, the effect will be completely different. " During his graduation thesis, he not only cultivated his ability of independent scientific research, but also laid a solid foundation for the future. Different rubber content and synthetic varieties have strong and weak impact resistance. Dai Liming has spent the last three or four months in the laboratory, and his daily life is full of problems such as content and performance. The rubber is unevenly dispersed and the dosage is not well controlled. After hundreds of experiments, I finally made a satisfactory "work".
Dai Liming graduated with the first place, and the school and Zhejiang Institute of Chemical Technology extended an olive branch to Dai Liming. After careful consideration and referring to the advice of his tutor Yuan Huigen, he finally chose Zhejiang Institute of Chemical Technology with better scientific research conditions. 1985, Dai Liming went abroad to study in Australian National University at his own expense. In three and a half years, Dai Liming was lucky enough to receive the guidance of John Wyatt, a former member of the Royal Society, and successfully completed his doctorate. "At that time, I devoted myself to research, and' conductive polymer materials' was a great achievement at that time." Adding rubber to plastic can make the original non-conductive plastic conductive, which can be widely used in aerospace field, reducing cost and weight, and secondly reducing fuel consumption. It was reported from 65438 to 0988 that the conductivity of this rubber was greatly improved after doping iodine, which caused a great sensation. Nature has reported this topic, but its transmission mechanism has not been clarified for a long time.
In 1992, Dai Liming first proposed that the mechanism of this kind of rubber conduction is that iodine is added first and then eliminated to produce * * * yoke structure on polydiene polymer chain, rather than super bond caused by iodine doping. On this basis, he used the characteristics of polybutadiene to selectively add iodine and eliminate hydrogen iodide. Through microlithography, he successfully carved conductive micron-scale line width patterns on polybutadiene rubber films. This simple and selective method of forming stable conductive patterns on polymer films is of great significance to the development of new conductive polymer materials and new printed circuit boards, integrated circuits and photoelectric storage devices. Due to his long-term research work on functional polymers and nanomaterials, Dai Liming has made a series of innovative research achievements in the research fields of carbon nanotube synthesis and assembly, conductive polymers, luminescent polymers, and new polymer photoelectric materials containing C60. Especially in the preparation and application research of array carbon nanotubes, it has achieved world-renowned research results and is now one of the world-renowned scientists in this field.
"The directional controllable growth and arrangement of carbon nanotubes is an important problem to be solved urgently in the basic research and application research of carbon nanotubes. The previously directionally grown carbon nanotubes were mainly realized by using porous templates. " In 200 1, Dai Liming successfully prepared large-area highly oriented carbon nanotube array films by pyrolysis of specific organometallic compounds without using templates.
Through electrochemical method, Dai Liming also realized the deposition of conductive polymer on the wall of each array of carbon nanotubes, and obtained the array of conductive polymer-carbon nanotubes coaxial nanowires. After application, his above-mentioned innovative achievements won six international patents. brief introduction
Dai Liming, the head of biochemistry lesson preparation for senior three in Hangzhou Yucai Middle School, is now a biochemistry teacher in grade seven and grade eight. He has been engaged in education for 30 years, and it is his consistent style to be loyal to education and work conscientiously. He has won many honors at the municipal, district and school levels in education, and 20 1 1 was named the first person of the year in Hangzhou Yucai Middle School. This is the greatest affirmation of his work by the leaders and all the teachers. Teacher Dai's work style is rigorous and practical. In the four-year talent training, she has been keeping a close eye on the biochemical teaching in grade three and achieved remarkable results. The scientific achievements of her class are among the best in Hangzhou in the annual senior high school entrance examination. Teacher Dai Liming's professional knowledge is solid and extensive, and he stands tall and sees far in teaching work. He usually expands his knowledge in classroom teaching, so that talented students can better adapt to innovative senior high school entrance examination questions, and the excellent rate of science in senior high school entrance examination is very high every year. Love students, treat students as children, and teach and educate people. This is the greatest advantage of Mr. Dai Liming. He is kind and has a harmonious relationship between teachers and students. Students are very enthusiastic about learning science, and like to take teacher Dai's class. He has been practicing his own style in classroom teaching: humorous and full of passion, so his classes always attract students firmly. He always sincerely cares about every student, makes friends with them, and patiently and meticulously counsels them after class, which won the high trust of students and the unanimous praise of parents, and also won the excellent scientific achievements of his class in recent years. He often said: the students of one session after another are his greatest pride, and the improvement of students' academic performance and achievements is his greatest satisfaction. Being a teacher by example, he treats others sincerely and has a harmonious relationship with his colleagues. As the leader of the biochemical group, he sets an example, unites his colleagues, cooperates sincerely in the group, takes the lead, cares for and helps young teachers, gives careful guidance in business and trains many apprentices. After making some achievements in his career, he is looking for a new breakthrough and opening up a new situation. Teacher Dai Liming has always had a goal in mind: to make the science group of Yucai Middle School a first-class science group in the province and make it another beautiful gold business card of Hangzhou Yucai Middle School.
