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.
