(54) Title: ION CONDUCTIVE SPACER, PREPARING PROCESS THEREOF AND ELECTRODIALYSIS REVERSAL STACK (57) : An ion conductive spacer for use in an electrodialysis reversal stack is disclosed, which includes a plastic netting and a polymeric coating coated on the plastic netting and containing charged groups. The morphology of the polymeric coating has interconnected ionic clusters which allow continuous and macroscopic ion transportation throughout a surface of the plastic netting. An electrodialysis reversal stack using the above ion conductive spacer and a process for preparing the above ion conductive spacer are also disclosed.
