abstract = {Here, we report a one-spot, temperature-controlled AC
electropolymerization strategy for converting graphene oxide and aniline
into a crystalline, processable reduced graphene oxide (rGO)/polyaniline
(PANI) composite for wearable ionic transistor textiles. By tuning the
electropolymerization temperature from 4 degrees C to 55 degrees C under
a low-frequency triangular AC waveform, followed by mild postreduction,
conformal polycrystalline PANI nanodomains are grown directly on rGO
sheets. Low-temperature synthesis yields the highest structural ordering
and the lowest fraction of protonated imine species, directly linking
growth conditions to mixed ionic-electronic transport behavior. The
resulting rGO/PANI composite functions as an electrolyte-gated
transistor with stable operation and amplified gate response.
Furthermore, the composite can be stencil printed onto cotton textiles
to realize ratiometric Na+/K+ sensing at constant ionic strength,
highlighting its potential for scalable, wearable ion-sensing
architectures.},
