使用具有超临界二氧化碳（scCO（2））可溶性嵌段的氟化嵌段共聚物作为模板，开发了一种新颖、简便且可重复的薄膜纳米细胞制造方法（见图）。纳米细胞的平均间距为34 nm，数密度为9 X 10(10) cm(-2)。通过改变 scCO(2) 的饱和压力可以轻松调节纳米细胞结构的尺寸。
A novel, facile, and reproducible method of fabricating nanocells in thin films (see Figure) has been developed using a fluorinated block copolymer with a supercritical carbon dioxide (scCO(2)) soluble block as a template. The nanocells have an average spacing of 34 nm and a number density of 9 X 10(10) cm(-2). The size of nanocellular structures is readily tunable by changing the saturation pressure of scCO(2).
