嵌段聚合物由于不同嵌段热力学不相容而形成微观相分离,进而发生自组装排列成规则有序的微观结构,其中网状结构是自组装微观结构中的复杂结构,具有令人瞩目的特性,在纳米科技领域应用价值极高,备受各国研究者的青睐。本文介绍了嵌段聚合物自组装原理和网状结构的特点,重点综述了两嵌段聚合物自组装结构中常见的三种网状结构的发展、制备方法以及在纳米科技中的应用,并指出当今网状结构的研究热点,预测该领域的发展趋势。
Due to the thermodynamic incompatibilities of different block blocks, the segmented polymers form a microscopic phase separation, which leads to the self-assembly of ordered and ordered microstructures. The reticular structure is a complex structure in self-assembled microstructures. Characteristics, high value in the field of nanotechnology, much of the researchers of all countries of all ages. In this paper, the principle of self-assembly of block polymers and the characteristics of network structures are introduced. The development, preparation and application of three kinds of network structures commonly seen in the self-assembly structure of diblock polymers are reviewed in detail. It points out the research hotspots in today’s mesh structure and predicts the development trend in this field.
