Description

technical field [0001] The invention relates to the field of ion exchange membrane materials, in particular to a biocompatible heterogeneous ion exchange membrane material and a preparation method thereof. Background technique [0002] The ion exchange membrane is a polymer membrane containing ionic groups and has the ability to selectively permeate the ions in the aqueous solution, also known as the ion selective permeable membrane. Ion exchange membrane occupies an important position in the field of membrane technology, and it will also play an important role in the research of biomimetic membranes. There are two main types of ion exchange membranes: homogeneous ion exchange membranes and heterogeneous ion exchange membranes. The homogeneous ion exchange membrane refers to a membrane in which the entire bulk phase of the membrane is made of active polymers (or ion exchange resins). The disadvantage of homogeneous membranes is that since they must be synthesized from basi...
