3D printed porous supramolecular sorbents

Abstract

Porous polymers known for their high surface area, adjustable pore size, and adsorption capabilities were explored for cobalt recycling using a supramolecular receptor and a photocurable porous polymer. A porous polymer structure includes a nanoporous polymer matrix having repeating units derived from a receptor monomer and, optionally, a support monomer, wherein the nanoporous polymer matrix comprises a plurality of nanopores having an average pore diameter of 1 to 1000 nanometers. Methods for fabricating porous polymer structures and methods for attaching a target metal species are also described.
