控制主客体之间的分子相互作用对于吸附和释放应用是相当重要的。为了解决这一挑战，聚合物离子液体（PIL）刷制备通过可逆加成断裂链转移聚合，其中我们证明，PIL赋予抗污染的材料的基础上的PIL的可计数性。用阴离子交换法制备了聚（1-乙烯基-3-丁基咪唑溴盐），用于控制主客体间的相互作用。测量所得表面的膜厚度、接触角和表面形态来确认环糊精官能化PIL刷的结构特征。具有可切换特性的PIL刷保护固定化的宿主分子免受不期望的相互作用，而在储存期间没有任何形态变化，并且在生物分离和生物传感器中具有潜在的应用。
The control of molecular interactions between host and guest is of considerable importance for adsorption and release applications. To address this challenge, polymeric ionic liquid (PIL) brushes were prepared via reversible addition fragmentation chain transfer polymerization, where we demonstrate that PILs confer a resistance to fouling of the material based on the counterion tunability of PILs. The anion-exchange of poly(1-vinyl-3-buthylimidazolium bromide) was used for the control of the host guest interactions. Measurement of film thickness, contact angle, and surface morphology of the resulting surfaces were used to confirm the structural characteristics of the cyclodextrin-functionalized PIL brushes. The PIL brushes with switchable properties protect the immobilized host molecule against undesirable interactions without any morphological changes during storage and has potential application in bioseparation and biosensors.
