Disclosed is a method and apparatus for providing polyiodide resin-enhanced personal protective equipment (PPE) including but not limited to face masks, gloves, gowns and respirators. The disclosed method comprises the application of a polyiodinated ink polymer in or on one or more targeted surfaces of PPE to create a molecular sub-microscopic protective barrier between the equipment and the user. The disclosed system provides a PPE device capable of direct contact kill of organisms. In addition, the system provides for a sustained kill of organisms for up to 96 hours. The resultant PPE device is broadly effective against viral, bacterial, fungicidal and other microbial agents.

This disclosure includes a polymer blend comprising. The polymer blend includes at least 60% by weight olefin-based polymer, and a diblock copolymer comprising an non-polar block and a polar block, wherein the diblock copolymer has a number average molecular weight number (M.sub.n) less than 5000 g/mol as determined by proton nuclear magnetic resonance (.sup.1H NMR); and wherein the non-polar block and the polar block are connected by a thiol linkage.
