  • TEMPERATURE-INSENSITIVE MEMBRANE MATERIALS AND ANALYTE SENSORS CONTAINING THE SAME
    Publication number: 20230365758
    Abstract: Membranes permeable to an analyte may overlay the active sensing region of a sensor to limit the analyte flux and improve the response linearity of the sensor. Temperature variation of the analyte permeability can be problematic in some instances. Polymeric membrane compositions having limited variation in analyte permeability as a function of temperature may comprise: a polymer backbone comprising one or more side chains that comprise a heterocycle; and an amine-free polyether arm appended, via an alkyl spacer or a hydroxy-functionalized alkyl spacer, to the heterocycle of at least a portion of the one or more side chains.
