Abstract

We report a facile one-step route to graft poly(ionic liquid)s (PILs) onto cellulose nanofibrils (CNFs). The dispersibility of the PIL-functionalized CNFs in water and various organic solvents could be tuned by the choice of the PIL-binding anion. We demonstrate that such omnidispersible PIL@CNF hybrids can be used to reinforce porous poly(ionic liquid) membranes.

摘要

我们报道了一种将聚离子液体（PILs）接枝到纤维素纳米纤维（CNFs）上的简便一步法。通过选择PIL结合阴离子，可以调节PIL功能化CNFs在水和各种有机溶剂中的分散性。我们证明，这种全分散的PIL@CNF杂化物可用于增强多孔聚离子液体膜。
