Abstract
A microporous membrane structure is disclosed that comprises a microporous membrane formed of a synthetic polymer and a substantially continuous porous coating on the membrane. The coating is formed from a urethane-based polymer, and provides a permeable barrier that does not interfere with the function of the membrane, and which will prevent further materials that are applied to or adjacent the membrane from interfering with the function of the membrane when those further materials are applied to the porous coating.
