Membranes having first and second porous portions, wherein the first portion has a more open pore structure than the second portion, wherein the first porous portion includes channels prepared by removing introduced fibers, as well as methods of making and using the membranes, are disclosed.

High throughput membrane with channels

Hydrophilic porous membranes comprising a random copolymer of:   

Robust polymeric membrane

Asymmetric membranes comprising a first asymmetric porous zone including a first porous asymmetry that increases from the first exterior surface through the first porous zone of the bulk, and a second asymmetric porous zone including a second porous asymmetry that increases from the second exterior surface through the second porous zone of the bulk, wherein the first average pore size is larger than the second average pore size, as well as methods of making and using the membranes, are disclosed.
