Breakthrough in the synthesis and application of water-soluble low dimensional materials
the team of academician Tian He and associate researcher he Xiaopeng of the feilinga Nobel Prize scientists joint research center of East China University of science and technology cooperated with the team of academician Yan Deyue and special researcher Mai Yiyong of Shanghai Jiaotong University in the controllable synthesis of water-soluble low dimensional materials Supramolecular self-assembly and its application in the field of biotechnology. Breakthroughs have been made in the consumption and scientific research expansion of raw materials and products such as rubber. Relevant research results were recently published in German applied chemistry
graphene and its low dimensional derivatives have excellent mechanical, photoelectric and magnetic properties, and are widely used in the field of biomedicine. In view of the defects that it is difficult to obtain graphene with accurate structure by traditional mechanical stripping and chemical methods, the controllable synthesis and application of graphene nanoribbons drafted by the Ministry of industry and information technology have become an international research hotspot in recent years. Whether it is good or not is simple and clear. However, the graphene nanobelt structure developed so far cannot be dispersed in water, which greatly restricts the research of its supramolecular self-assembly structure and its application in the field of life science
aiming at these key problems, researchers have synthesized a series of graphene nanobelts with good water dispersity by modifying graphene nanobelts with precise structure with hydrophilic polyethylene oxide (PEO), and accurately marked the low dimensional supramolecular self-assembly in its aqueous phase in table 3.4. Based on the characteristics of strong absorption in the near-infrared region of its aqueous dispersion, researchers for the first time confirmed that this kind of graphene nanobelt self-assembly with precise structure can efficiently convert photon energy into heat energy under the radiation of near-infrared light, successfully realizing the polymer functionalization and aqueous dispersion of graphene nanobelts with precise structure, and opening up a new precise chemical way to obtain water dispersed graphene nanobelts with new properties, It also provides new insights for the preparation of structurally controllable low dimensional materials and their applications in the field of disease diagnosis and treatment, such as photoacoustic imaging and photothermal therapy
