Can you suggest a mechanically strong semipermeable (permeable to liquid and impermeable to gas) material?

I want to separate a stream of liquid and a stream of gas for an experiment. It is best suitable when the material is permeable to gases but impermeable to the liquid. Your valuable suggestions...
