In the sequential method for preparing a double- network membranes, the second network will be created in the presence of the first one
Can both network be from the same polymer solution ??
It is possible to make a semi-IPN using the same solution by immersion. However, "DN is characterized by a special network structure consisting of two types of polymer components with different physical natures"
