Abstract
A conductive quasi-solution useful for making a homogeneously conductive single-phase polyurethane, comprising a transition metal salt, a carrier solution, and a dispersing agent, wherein said conductive quasi-solution has a transition metal salt concentration between 10 and 30% by weight, and methods of making thermoset and thermoplastic polyurethane polymers therewith.
Claims1
A method of making a homogeneously conductive single-phase polyurethane, comprising
- preparing a conductive quasi-solution comprising a transition metal salt, a carrier solution, and a dispersing agent, wherein said transition metal salt is present in a concentration between 10 and 30% by weight;
- and
- mixing an amount of said conductive quasi-solution with a diisocyanate and a polyurethane precursor selected from polyols and polyamines to form a homogeneously conductive single-phase polyurethane.
