  • IMMOBILIZATION OF INSOLUBLE PARTICLES IN POLYMER
    Publication number: 20220403119
    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.

  • Process and method for fabricating wearable and flexible microfluidic devices and systems
    Patent number: 10285640
    Abstract: A new fabrication process for flexible and wearable microfluidic channel structures and devices is provided. Microfluidic channel structures and devices can be printed on textiles and in particular on flexible fabrics, such as clothing, for applications in wearable microfluidic sensors and systems. The wearable and flexible microfluidic devices are fabricated from water-insoluble plastisol polymers, which may be screen-printable, and sheets of paper may be used as a sacrificial substrate during production.
