Composite fluid separation membranes |
| abstract |
Membranes which have a non-porous intermediate layer (8) between a separating layer (2) and a porous support (4) are taught wherein the in situ-formed non-porous intermediate layer (8) positioned between a porous support (4) and an in s i tu-formed separating layer (2), results in composite fluid separation membranes having improved permeability for the separation of fluids. The highly permeable intermediate layer (8) provides spacing between the separating layer (2) and the porous support (4) which creates a funnel effect (12, 14) for the fluid from the separating layer (2) to the pores (6) of the porous substrate (4). |
