摘要:It is an efficient way to improve the properties of proton exchange
membranes (PEMs) by the method of chemical cross-linking. The
cross-linked PEMs have the advantages of low water uptake, low methanol
crossover, high thermal and mechanical stability. There are three
methods to perform cross-linking. These are sulfonation of a
cross-linked polymer, cross- linking of a sulfonated polymer, and
cross-linking of a polymer blending system. Different cross-
linkingmethods lead to different cross-linking sites and consequently
different properties of the PEMs. Cross-linking degree, ion exchange
capacity or cross-linker species may have profound effects on
microstructure and properties of the cross-linked membranes. They should
be optimized in order to make the best of the properties of cross-linked
PEMs.
