Abstract: Forming a dual layer filtration membrane includes disposing a first solution with a homopolymer and a first solvent on a substrate to yield a homopolymer layer on the substrate; disposing a second solution with a block polymer and a second solvent on the homopolymer layer to yield a dual layer liquid film having a block polymer layer on the homopolymer layer; disordering the block polymer layer to yield a disordered block polymer layer; vitrifying the disordered block polymer of the disordered block polymer layer and inducing phase separation and vitrification of the homopolymer of the homopolymer layer; and creating pores in the disordered block polymer layer to yield the dual layer filtration membrane having a porous disordered block polymer layer.

Abstract: Provided herein are polymeric capsules and methods for solvent-free extractive separation of ions from mixed solutions using polymeric capsules. The capsules can comprise a polymeric shell encasing an inner chamber and a lipophilic ligand within the polymeric shell. Methods for making the polymeric capsules are also provided.
