Isoporous block copolymers of cross-linked structures, and methods of preparing, which are resistant to harsh solvent conditions from organic, acidic or basic materials are disclosed.

Chemically resistant isoporous crosslinked block copolymer structure

A method for forming an isoporous graded film comprising multiblock copolymers and isoporous graded films. The films have a surface layer and a bulk layer. The surface layer can have at least 1×10pores/mand a pore size distribution (d/d)) of less than 3. The bulk layer has an asymmetric structure. The films can be used in filtration applications.

Multiblock copolymer films, methods of making same, and uses thereof

The invention provides systems and methods for substantially improving the compaction resistance of isoporous block copolymer (BCP) film by adding a high molecular weight hydrophilic additive in the casting dope formulation. Systems and methods disclosed also disclose several other multifunctional enhancements to film properties including: low fouling propensity, improved permeability, improved permeability retention upon drying, and ability to tune the substructure and pore size of these novel BCP films. These porous BCP films are useful in filtration and separations applications and are amenable to standard manufacturing practices.

Isoporous self-assembled block copolymer films containing high molecular weight hydrophilic additives and methods of making the same

Multiblock polymer materials, methods of preparing, and using to separate proteins, nucleic acids, other biological or other biomolecules, compounds, or solutes, with high fluxes through electrostatic interactions where the self-assembled block polymer materials contain at least one of macro, meso, or micro pores, and at least some of the pores are isoporous, and at least one polymer block contains stationary electrostatic charge, or reactive functional groups to provide large surface areas that are charged in isoporous structure.

Charged isoporous materials for electrostatic separations

Multi-block isoporous structures for non-aqueous and/or harsh chemical media having at least one of high separation specificity, chemical resistance, and antifouling properties, methods of manufacturing and use, for replacements or alternatives to existing separation membrane technologies.

Chemically resistant fluorinated multiblock polymer structures, methods of manufacturing and use

A mesoporous isoporous asymmetric material includes at least one diblock or multiblock copolymer, wherein the material has a transition layer having a thickness of at least 300 nm and a low macrovoid density, and the material has a sub-structure adjacent to said transition layer and said sub-structure comprises a high macrovoid density. A method for producing mesoporous isoporous asymmetric materials having macrovoids can include: dissolving at least one diblock or multiblock copolymer in a solution, the solution having one or more solvents and one or more nonsolvents, to form a polymer solution; dispensing the polymer solution onto a substrate or mold, or through a die or template; removing at least a portion of solvent and/or nonsolvent from the polymer solution to form a concentrated polymer solution; and exposing the concentrated polymer solution to a nonsolvent causing precipitation of at least a portion of the polymer from the concentrated polymer solution.

Isoporous mesoporous asymmetric block copolymer materials with macrovoids and method of making the same

Compositions and methods are described for self-assembled polymer materials having at least one of macro, meso, or micro pores.

Ligand bound MBP membranes, uses and method of manufacturing

A method for forming an isoporous graded film comprising multiblock copolymers and isoporous graded films. The films have a surface layer and a bulk layer. The surface layer can have at least 1&#xd7;10pores/mand a pore size distribution (d/d)) of less than 3. The bulk layer has an asymmetric structure. The films can be used in filtration applications.
