Ion exchange membrane is a polymer membrane that contains ionic groups and has the ability to selectively transmit ions in the solution. Cation exchange membrane refers to a membrane that has a selective effect on cations. It is usually a sulfonic acid type and can be regarded as a polymer electrolyte. There are two methods for preparing ion exchange membranes: membrane surface treatment and membrane body modification. Cation exchange membranes have the advantages of high permeability, low energy consumption, excellent conductivity, low resistivity, and long service life, and have broad application prospects in the field of water treatment.

​​According to different functions and structures, ion exchange membranes can be divided into three types: cation exchange membranes, anion exchange membranes and bipolar membranes. In recent years, driven by national policy support and market demand, the development of my country’s ion exchange membrane industry has accelerated. As a segmented product, the market space for cation exchange membranes has continued to expand.

According to the “2023-2028 China Cation Exchange Membrane Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center, The water treatment field is the largest demand end for cation exchange membranes, which can be used for seawater desalination, drinking water purification, and industrial wastewater treatment. The use of cation exchange membranes to treat high-salt wastewater can effectively remove organic pollutants contained in the water to achieve the purpose of fully recovering and recycling water resources. In recent years, the country has attached great importance to the development of the water treatment industry and introduced many policies to support it. Cation exchange membranes can effectively improve the efficiency of industrial wastewater treatment. Driven by market demand, the industry’s prosperity continues to increase.

The world’s leading cation exchange membrane companies are mainly concentrated in European and American countries, including German FuMA-Tech, German Sartorius, American Electropure, American Versogen, etc. The main cation exchange membrane manufacturers in my country include Langfang Yadeshi Environmental Protection Equipment Co., Ltd., Wuxi Metas Applied Materials Technology Co., Ltd., Shandong Tianwei Membrane Technology Co., Ltd., Hangzhou Glinda Electronic Materials Co., Ltd., etc.

In recent years, my country’s research and development of cation exchange membranes has been enthusiastic and has made many new progress. In April 2023, the School of Chemistry and Materials Science of the University of Science and Technology of China officially launched the “Design and Preparation of High Stability Homogeneous Ion Exchange Membrane” project implementation plan. At present, the project research team has successfully developed cation exchange membrane materials, and is expected to be used in the future. Breakthroughs were made in the key preparation technologies of mono/bivalent high selectivity and multifunctional high stability cationic membranes.

Industry analysts said that as an emerging material, cation exchange membranes have broad application prospects in the field of water treatment and will be gradually released in the future with market demand. , the industry development speed will continue to accelerate. In recent years, my country’s research on cation exchange membranes has been highly enthusiastic. In the future, with in-depth research and technological advancement, the application scope of my country’s cation exchange membranes will be further expanded, and high performance will become the mainstream development trend of the industry.
