Antimicrobial phase-separable glass/polymer articles and methods for making the same

A method of making an antimicrobial article, comprising the steps:

• mixing particles comprising a phase-separable glass with a copper-containing antimicrobial agent with a matrix precursor comprising polymeric particles to define an antimicrobial mix;
• forming the antimicrobial mix into an antimicrobial composite film comprising a matrix and a first plurality of the particles within the matrix at a volume fraction;
• and
• affixing the antimicrobial composite film to a primary surface of a bulk element;
• wherein the matrix comprises a polysulfone;
• and
• wherein the affixing comprises lamination or hot pressing.

A method of making an antimicrobial article, comprising:

• extruding a mixture of polymer and copper-containing phase-separable glass into an antimicrobial composite film;
• and
• affixing the antimicrobial composite film to a primary surface of a bulk element;
• wherein the affixing comprises lamination or hot pressing.
