Block copolymer thin films are highly versatile and accessible materials capable of producing nanofeatures in the size regime of a few to hundreds of nanometers by a simple spin‐coating‐and‐anneal process. Unfortunately, this simple protocol usually leads to parallel microdomains, which limits the applicability of such nanofeatures. A great deal of effort has been put into achieving perpendicular microdomains, but those that incorporate thermal annealing are arguably the most practical and reproducible in the lab and industry. This review discusses the recent ongoing efforts on various thermal approaches to achieving perpendicular microdomains in order to provide the readers with a toolbox to work with.

薄膜中垂直嵌段共聚物微区的热学方法：评述与评价

嵌段共聚物薄膜是一种用途广泛且易于获得的材料，能够通过简单的旋涂和退火工艺产生几纳米至几百纳米大小的纳米特征。不幸的是，这种简单的协议通常会导致并行的微域，从而限制了此类纳米功能的适用性。在实现垂直微区方面已经付出了巨大的努力，但是可以肯定的是，结合了热退火的微区在实验室和行业中是最实用且可重现的。这篇综述讨论了最近为实现垂直微区而采用各种热方法的努力，以便为读者提供一个可以使用的工具箱。
