Microstructure of Teflon proton exchange membrane
The Teflon proton exchange membrane is a thin film with a thickness of only 50-180um. Its microstructure is very complex. It provides a channel for proton transfer and serves as a separator to separate the fuel in the anode from the oxidant in the cathode. An excellent material.
Is there just one kind of perfluorinated polymer material? Far from it, there are many.
Let’s look at various film-forming polymers, all of which can be used.
The front ones are all fluorine cross-linked ones, which are put together one by one. There are also cross-linked ones, knotted ones, and various structures.
Every household’s situation is different.
This is its molecular structure. It is this small dot and this small dot that can conduct protons. The content is very small. Therefore, there is still a lot of room for the development of fluorine-containing film-forming materials. We are not talking about development here now. It’s over, far from it.
Teflon proton exchange membrane has the advantages of high tensile strength, high conductivity, and good chemical properties.
After composite reinforcement with PTFE reinforced mesh, the strength is greatly improved and the swelling rate is lower.
According to the usage requirements, the pore diameter can be between 0.1-10um, the thickness can be between 2-100um, and the porosity can reach 50%–80%. It can be operated at a continuous operating temperature of 240°C and an instantaneous temperature of 260°C. .
It is a high-tech enterprise specializing in the research and development, production and sales of Teflon proton exchange membranes. It has a factory area of nearly 8,000 square meters and professional production equipment. It is a partner of the top 500 companies in the United States; we The products produced are all produced from imported raw materials, with finer molecular weight, cleaner quality and better uniformity.
