An
approach to overcome drawbacks of well-established transducer
materials for all-solid-state ion-selective electrodes is proposed;
it is based on the formulation of the nanocomposite of multiwalled
carbon nanotubes (MWCNTs) and poly(3-octylthiophene-2,5-diyl) (POT),
in which the polymer is used as a dispersing agent for carbon nanotubes.
Thus, the obtained material is characterized with unique properties
that are important for its application as solid contact in ion-selective
electrodes, including high: electronic conductivity, capacitance,
and lipophilicity. Performance of the obtained all-solid-state electrodes
was studied using a standard approach as well as Raman spectroscopy
to allow insight into distribution of the transducer material within
the sensor phases: the membrane and the transducer. Application of
the composite prevents unwanted partition of POT to the membrane phase,
thus eliminating the risk of alteration of the sensor performance
due to uncontrolled change in the membrane composition.
