Abstract:Polymeric membranes are susceptible
to aging and plasticization,
which alters their separation properties since polymeric chain mobility
within the membrane matrix is greatly affected. Hence, the implementation
of these materials in industrial applications has been limited. However,
cross-linking of polymeric membranes is a robust methodology to enhance
their physical and mechanical properties. In this regard, thermal
cross-linking is advantageous over chemical cross-linking since it
could be applied directly … Show more
