Abstract
Reviews the many crosslinking methods for polyimide membranes that have been described in the literature. Authors summarize important properties of polyimides and their synthesis reactions. They enumerate the important commercialized polyimide types that are now used in membrane technology, the preparation methods available for polyimide membranes and their main applications.
They describe the effects of thermal annealing of polyimide membranes, as prelude to an extensive review of the many crosslinking methods that have been described in literature. Thermal crosslinking, UV crosslinking and a range of chemical crosslinking methods, including diol and diamine crosslinking, are described, focusing on the actual chemistry behind the crosslinking.
