Invention Summary

A method of making blended, isoporous graded films from block copolymers.

Technology Overview

Using block copolymers (BCPs) in preparing asymmetric ultrafiltration (UF) membranes can yield isoporous materials with highly ordered surfaces and permselectivity
Integrating BCP self-assembly with non-solvent-induced phase inversion (SNIPS) gives rise to membranes with tailored pore sizes
Unmet need: the SNIPS process has not been applied to mixtures of two or more chemically distinct BCPs
Cornell researchers have developed asymmetric membranes having isoporous surface structure from two chemically distinct block copolymers
Membranes fabricated in this way enable different pore surface chemistries within the single membrane without the need for post-fabrication steps
The use of distinct BCPs may enable new capabilities in selectively (e.g., in complex protein separations)
