A method, comprising:
- placing an HM alginate solution on a hydrophilic porous membrane;
- exposing the HM alginate solution on the hydrophilic porous membrane to a vacuum pressure to produce a hydrophilic porous membrane impregnated with HM alginate;
- exposing the hydrophilic porous membrane impregnated with HM alginate to a cross-linking solution to cross-link the HM alginate and produce a hydrophilic porous membrane impregnated with cross-linked HM alginate;
- and
- lyophilizing the hydrophilic porous membrane impregnated with cross-linked HM alginate to produce a composite membrane.
