Abstract
En 中文
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°C to 55°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.
