中文摘要：

对以嵌段聚合物为模板制备聚合物纳米多孔材料的研究进行了评述，重点介绍了超临界流体选择溶胀法制备聚合物纳米多孔材料新技术。与传统方法相比，利用超临界二氧化碳（scCO2）对含亲CO2组分嵌段聚合物的选择溶胀性，在聚合物材料中引入了纳米闭孔结构的的技术具有非破坏性优点。除此之外，该方法能够获得非平衡态下的多种聚合物纳米结构，改变了以往只能在平衡态下通过化学刻蚀或热降解等方法获取纳米多孔结构的方式，拓展了超临界流体在材料制备中的应用。

英文摘要：

Block copolymer （bcp） templates have been intensively studied to fabricate a variety of nanostructures. Creating nanocellular and porous polymeric materials using bcp templates is a branch of objectives of the bcp template techniques. Conventional methodologies to fabricate porous polymeric materials are based on decomposition of particular bcp domains using ozone, biodegradation, and ultraviolet light. In this review, we report a novel, environmentally benign method using CO2 to fabricate nanocellular polymeric materials using a fluorinated bcp as the template.
