A Study of Preparing Self-assembly Brush Polymer by Quartz Crystal Microbalance
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
F
and Δ
D
as a function of time was recorded. Results indicated that Δ
F
decreased and Δ
D
increased significantly in the initial stage
and they both changed slowly and gradually reached equilibrium. When deionized water was passed into the sample cell
Δ
F
increased and Δ
D
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.
