General description

Poly(ethyleneimine) (PEI) solution is an amine based chelating ligand that can be prepared by the polymerization of arizidine. It can be impregnated to form an anion exchange membrane for chromatography applications.

Application

PEI can be used as a complexing agent in the fabrication of composite membranes, which can be used in filtration of metals from the aqueous solution.

New methods for materials fabrication at the micro- and nanoscale will drive scientific and technological advances in areas of materials science, chemistry, physics, and biology. The broad diversity of potentially relevant materials, length scales, and architectures underscores the need for flexible patterning approaches. One important example is the fabrication of 3D periodic structures composed of colloidal, polymeric, or semiconductor5 materials.
