概要
- 論文の詳細を見る
The pH-sensitive swelling of a xanthan/chitosan complex gel, which swelled in NaOH solutions of pH 9-12, was analyzed by the collective diffusion model developed by Tanaka and Fillmore, which is based on the diffusion of a polymer network. The time-course for swelling of the gel beads under a change in pH from 11 to 10 fitted well with the equation derived by Tanaka and Fillmore. The collective diffusion coefficient characteristic of the gel was also obtained, although the value of this coefficient was higher than that of the cooperative diffusion coefficient determined from dynamic light scattering experiments by about 4 orders of magnitude. This result indicates that the swelling rate of the gel due to pH change was not controlled by cooperative diffusion of the polymer networks.
