Document Type and Number:
Japanese Patent JP2008260015
Kind Code:
A
Abstract:

To provide a method for manufacturing an alternate adsorption membrane, which can stably manufacture a high-quality alternate adsorption membrane by a relatively simple manufacturing apparatus.

This method for manufacturing an alternate adsorption membrane comprises a positively charged material having positive charge and a negatively charged material having negative charge both stacked alternately on the surface of a film forming material. The method comprises at least a positively charged material-containing liquid coating step of delivering and coating a positively charged material-containing liquid containing the positively charged material to form a liquid film on the surface of the film forming material and a negatively charged material-containing liquid coating step of delivering and coating a negatively charged material-containing liquid containing the negatively charged material to form a liquid film on the surface of the film forming material. The positively charged material-containing liquid coating step and the negatively charged material-containing liquid coating step are repeated by the number of times of stacking necessary for providing the alternate adsorption membrane.
