概要
- 論文の詳細を見る
Dynamic polyion complex membrane (PIC-DM) was formed by depositing a mixture of two oppositely charged polyions, sodium polyacrylate and polyethylene imine. The effect of composition on solute rejection by the PIC-DM formed was investigated.<BR>The rejection curve of the PIC-DM shifted to the higher-molecular weight side with increase of the charge amount of excess polyion in the mixture. The membrane structure evaluated from the solute rejection property was analyzed successfully by dual pore sizes model. The pore sizes and their number fractions were related to the ratio of charge of the polyions.
