Abstract
Polymeric membranes are modified via SIS to promote membrane resilience, prolong membrane lifetime, and mitigate fouling. Modified membranes include an inorganic material within an outer portion of the modified membrane and a polymeric core that remains unmodified by the inorganic material. The polymer may be removed leaving an inorganic material patterned from an initial unmodified polymeric membrane.
