课题天然高分子聚集态结构表征方法（Topic characterization methods of natural polymer aggregation structure） Topic, Aggregation and characterization of natural polymers Natural polymers are polymers found in natural organisms. As the basis of life including protein; nucleic acid exists in living cells of plants and animals; polysaccharides and microorganisms; plant lignin; natural rubber in the presence of lacquer and lacquer; marine chitin, algae etc.. First, the purpose, significance and research trends at home and abroad: (1) purpose and significance of research 1, the purpose of the study is to study the molecular chain structure of natural polymer, the interaction between molecules, molecular motion, condensed molecular structure, the hierarchical structure influence on the macroscopic properties of polymer and characterization of the polymer and its properties of polymers. The study of condensed matter of polymers is one of the important fields in polymer physics, and this part belongs to condensed matter Category. 2 、 research significance. Studying the structure and characterization methods of natural polymer aggregates can improve and improve the optical and mechanical properties of materials, and contribute to the study of new materials. For example, the preparation of liquid crystalline polymers by the modification of natural polymers with cellulose and chitin. (two) research trends at home and abroad Condensed polymer physics involves physics, chemistry, interdisciplinary materials, since the 1991 French scientist P. G. de Gennes won the Nobel prize in this field has been paid attention, in recent years, new development peak. However, the domestic research in this field is still lacking. Two. Main research contents, (1) background: when many long-chain polymers are aggregated into polymers, the states of molecules are stacked and arranged (in physics, the aggregation of molecules is called condensed matter). In many cases, the aggregation of molecular chains in polymers is
