本课题利用超支化聚合物制备纳米金属分散液，研究超支化聚合物对纳米金属溶液的制备和分散机理。在前期研究的基础上合成具有长链结构的超支化聚合物，该化合物的亲水链段和疏水链段在水溶液中会形成网状胶束，这些网状胶束可以在水溶液中控制纳米金属材料的生成。研究超支化聚合物结构对制备的纳米金属颗粒的大小、分散性和稳定性的影响，期望制备出具有稳定结构的纳米金属分散液。进一步利用纳米金属分散液整理纤维素纤维和织物，研究纳米金属颗粒在纤维上的吸附剂机理，总结整理工艺对纤维素纤维后整理的影响。测试整理后纤维和织物磁性，抗菌性，紫外线防护等功能性的变化。本研究对超支化聚合物合成纳米材料与具有指导意义，同时为纤维素纤维的功能化改性提供了新的思路。

In this project，hyperbranched polymer are used for the synthesis of nano metal dispersion ,the mechanism of the nano metal dispersion fabricated by hyperbranched polymer are studied. Based on the previous study, the hyperbranched polymer with long polymer chain molecular structures is further synthesized in this study. The hydrophilic chain segment and hydrophobic chain segment in the polymer can form a network micelles in aqueous solutions and this micelles can control the fabrication of nano metal. In order to synthesis the nano metal dispersion with solid structur, the structure of hyperbranched polymer affects the size, dispersion and stability of the metal particles are studied. This project also studied the treatment of cellulose fiber by nano metal dispersion, the adsorption mechanism of nano metal on the fiber are discussed. The performance of the treated cellulose fiber such as magnetic, antimicrobial properties, UV protection are tested. The research have guiding significance for the synthesis of nano metal materials, meanwhile the study can provide ideas for the functional treatment of cellulose fiber.
