Abstract

The advancement of wearable ion sensors necessitates ion-selective electrodes (ISEs) with high sensitivity and rapid response kinetics. This study introduces a porous conductive film based on a carbon nanocoil (CNC)/Ti 3 C 2 T x composite for ISE design. The Ti 3 C 2 T x nanoflakes, exhibiting metallically conductive behavior and abundant surface functional groups, form the film’s structural backbone, ensuring stability and superior electrical conductivity. Concurrently, the helical morphology of CNCs induces a porous architecture, significantly enhancing the ion transport efficiency and ion-to-electron transduction pathways. Consequently, the sensor demonstrates high sensitivity (62.3 mV/decade) and a fast response (0.08 s).
