摘要

利用石英晶体微天平研究β-环糊精修饰的壳聚糖与金刚烷甲酸聚乙二醇单甲醚酯进行主客体自组装的过程

从而制备刷状聚合物. 结果显示: 吸附初期

显著上升

随后两者变化都不大

逐渐达到平衡

向样品池通入去离子水

稍微上升而Δ

稍微下降. 这表明

在自组装过程中

β-环糊精与金刚烷发生包结络合作用

界面上吸附的高分子链发生了构象变化. 这一工作为研究固/液界面的主客体自组装反应过程提供了新的途径.

Abstract

The host-guest self-assembly process between β-cyclodextrin modified chitosan (the host polymer) and methoxypoly (ethylene glycol) adamantane carboxylate (the guest polymer) was studied by quartz crystal microbalance

which further prepared brush polymer. Quartz crystal surface

which was coated

was placed in the sample cell for testing. After the baseline was balanced

solution was passed into the sample cell. At the same time

the change in Δ

and Δ

as a function of time was recorded. Results indicated that Δ

decreased and Δ

increased significantly in the initial stage

and they both changed slowly and gradually reached equilibrium. When deionized water was passed into the sample cell

increased and Δ

decreased slightly until balance was reached. This information demonstrated the host-guest self-assembly between β-cyclodextrin and adamantane and this process showed two dynamic procedures coupled with chain conformational changes of polymer. This work may provide a new method for the research of the host-guest self-assembly process on solid/liquid interface.
