摘要
Water and salt transports through a charge-mosaic membrane prepared from a pentablock copolymer of the ISBAI type were investigated by using aqueous solutions of KCl. The membranes showed a very high permeability for KCl, pronounced negative osmosis, and piezodialysis. The data were analyzed according to the phenomenological equation by O. Kedem and A. Katchalsky.
