42 Claims

1. An antimicrobial structure comprising:

(a) a solid structural phase comprising a solid structural material, wherein said solid structural material is a solid structural polymer selected from the group consisting of a non-fluorinated carbon-based polymer, a silicone, a fluorinated polymer, and combinations thereof;

(b) a continuous transport phase that is interspersed within said solid structural phase, wherein said continuous transport phase comprises a solid transport material, and wherein said continuous transport phase contains an antimicrobial agent and a transport-phase liquid that at least partially dissolves said antimicrobial agent; and

wherein said antimicrobial agent is electrically or electrochemically rechargeable when a voltage is applied between said first and second electrodes,

and wherein said solid structural phase and said continuous transport phase are separated by an average phase-separation length from about 100 nanometers to about 500 microns.
