Abstract
A polymeric carrier composition including a polymer synthesized from monomers selected from acrylic acids, methylacrylates and urethanes and at least one metal having an oxidation state of +1 or +2, including salts and coordination complexes thereof. The composition may be a suspension having 0.5 to 10% by weight of the polymer prepared from monomers selected from a group consisting of acrylic acids, methylacrylates and urethanes, and a viscosity less than 1,000 cps. The composition is applied to substrates, such as woven fabrics, to create metal-infused articles.

A polymeric carrier composition for use in the manufacture of metal-infused fabric and garments comprising:
- a polymer consisting of polyurethane;
- copper (II) sulfate pentahydrate present at 50 to 70% by weight of the composition;
- and
- at least one water soluble zinc salt or coordination complex having an oxidation state of +1 or +2;
- wherein the composition is a suspension, wherein the polyurethane is synthesized from a polyol and an isocyanate compound, and wherein the zinc is reactive after combination with the polymer.
