Herein, we report the water-assisted self-assembly of alternating copolymers bearing imidazolium cations and hydrophobic groups to create water-compatible and nanostructured materials. The copolymers efficiently absorbed water into the cationic segments from the outer environments, depending on the relative humidity. The absorbed water serves as hydrophilic molecules to modulate the weight fraction of hydrophilic/hydrophobic units in the samples. Thus, the morphologies and domain spacing of the nanostructures can be controlled by not only the side chains, but also the amount of absorbed water. The self-assembly of the cationic copolymers, developed herein, afforded universal access to various morphologies, including lamella, gyroid, and cylinder, in addition to the precision control of the domain spacing at the 0.01 nm level.

通过阳离子交替共聚物的自组装普遍获得水相容性纳米结构材料


在此，我们报告了带有咪唑鎓阳离子和疏水基团的交替共聚物的水辅助自组装，以产生水相容的纳米结构材料。根据相对湿度，共聚物有效地将外部环境中的水吸收到阳离子链段中。吸收的水作为亲水分子来调节样品中亲水/疏水单元的重量分数。因此，纳米结构的形态和域间距不仅可以通过侧链来控制，还可以通过吸收的水量来控制。本文开发的阳离子共聚物的自组装除了在 0.01 nm 水平上精确控制域间距外，还可以普遍获得各种形态，包括层状、螺旋状和圆柱状。
