纳米结构嵌段共聚物（BCP）薄膜是一种生成复杂周期图案的优雅工具，其周期范围从几纳米到数百纳米。这种组织良好的纳米结构有望使下一代纳米制造研究在生物学、光学或微电子的功能材料设计中具有强大的应用。然而，这个有价值的平台受到双嵌段共聚物结构的几何特征的限制，考虑到热力学驱动力倾向于形成最小化嵌段之间界面的结构。因此，丰富BCP自组装过程获得的各种结构的策略正在获得动力，本进展报告通过考虑产生“非原生”形态的新兴策略，回顾了迭代BCP自组装所固有的机会。
Nanostructured block copolymer (BCP) thin films constitute an elegant tool to generate complex periodic patterns with periodicities ranging from a few nanometers to hundreds of nanometers. Such well-organized nanostructures are foreseen to enable next-generation nanofabrication research with potent applications in the design of functional materials in biology, optics or microelectronics. This valuable platform is, however, limited by the geometric features attainable from diblock copolymer architectures considering the thermodynamic driving force leaning toward the formation of structures minimizing the interface between the blocks. Therefore, strategies to enrich the variety of structures obtained by BCP self-assembly processes are gaining momentum and this progress report reviews the opportunities inherent to iterative BCP self-assembly by considering the emerging strategies for the generation of "non-native" morphologies.
