Zusammenfassung:Some embodiments of the present disclosure relate to a composite membrane. In some embodiments, the composite membrane comprises a first fluoropolymer membrane and a second fluoropolymer membrane. In some embodiments a difference between a second surface energy of the second fluoropolymer membrane and a first surface energy of the first fluoropolymer membrane is at least 10 mN/m at 20° C. In some embodiments, the composite membrane has a Z strength of at least 5 psi.
