US 12,534,580 B2 · Immobilization of insoluble particles in polymer

Abstract

A method of immobilization of an insoluble dopant. In some embodiments, the insoluble dopant comprises a coordination polymer. In some embodiments, the insoluble dopant comprises a vapochromic coordination polymer. The method may comprise dissolving a polymer carrier in a solvent. The polymer carrier may comprise a thermoplastic such as, but not limited to, polylactic acid, polyethylene glycol or polycarbonate. The insoluble dopant (e.g. a coordination polymer such as a vapochromic coordination polymer) may then be mixed into the dissolved polymer. Phase separation of the mixture of the dopant and dissolved polymer may be induced to form a hydrogel. The hydrogel may be employed as is (e.g. as a raw material for hydrogel 3D printing, as a sensing material, etc.) or may undergo further processing (e.g. solidification, grinding, extrusion, etc.) before being employed, for example, as a raw material for 3D printing, as a sensing material, etc.
