  • Publication number: 20230097289
    Abstract: Some variations provide a sensing system configured to measure the concentration of an antimicrobial agent in a polymer, comprising: a polymer containing (i) a discrete solid structural phase comprising a solid structural polymer and (ii) a continuous transport phase comprising a solid transport polymer and capable of containing the antimicrobial agent; and an antimicrobial-agent sensor that chemically senses the antimicrobial agent. The antimicrobial-agent sensor is disposed on a surface of, and in mass transport with, the polymer. The antimicrobial-agent sensor contains a responsive material disposed on or within a carrier material. The responsive material is chemically reactive with the antimicrobial agent and exhibits an observable and quantifiable property change upon chemically reacting with the antimicrobial agent. The observable and quantifiable property change may involve chromaticity, optical transparency, ionic conductivity, or electronic conductivity, for example.
