■ Poly (phthalazinone ether sulfone) with biphenyl structure and its preparation method■ Poly (phthalazinone ether ketone) with biphenyl structure and its preparation method■ Sulfonated poly (phthalazinone ether ketone) proton exchange membrane material and its preparation method This award-winning project introduces a new poly (phthalazinone ether sulfone ketone) with biphenyl structure and its preparation method. The project is one of the comprehensive achievements of national key scientific and technological projects, the 863 Plan and key provincial and municipal key projects. After novelty search and expert appraisal, it is confirmed as the first and original innovation in the world, ranking at the international leading level. Its synthesis process is simple, easy to control, high product yield, easy to refine, low cost and optimal cost performance. It can be widely used in aerospace, electronic and electrical, nuclear energy, machinery, automobile, petrochemical, environmental engineering and other industries, showing unique advantages. Dalian Baolimo New Materials Co., Ltd., a joint venture established for the industrialization of this technology, has built a 500t/a production line, and its products are exported at home and abroad, with rapid market expansion and remarkable economic benefits.
In 2003, the team led by Qi won the second prize of technical invention in the national competition (the first prize was vacant for six years in a row), and its award-winning "Novel polyethersulfone ketone with naphthalene biphenyl structure and its preparation method" replaced foreign imported products, which promoted the progress of cutting-edge science and technology in the domestic material field.
On 20 12, Professor Jian presided over the completion of "High-performance poly (aryl ether nitrile sulfone) series resin and its new application technology" and won the second prize of national technological invention again. The project "Heteronaphthalene biphenyl polyether nitrile sulfone series high-performance resin and its new application technology" belongs to the field of special organic polymer materials science and technology, and is one of the innovative achievements of the national "863" plan and the tenth five-year plan of Liaoning Province. After expert appraisal, it was confirmed as "the world's first scientific research achievement with original innovation and reaching the international leading level" and has been industrialized. Its deep-processed products have been widely used in aerospace, electronic and electrical, nuclear energy, petrochemical and other fields.
