摘要

The majority of flexible electronic devices are currently constructed using petroleum-based materials that are challenging to degrade. The pursuit of sustainable and environmentally friendly materials has become a significant area of interest for the scientific and industrial communities. In this study, bacterial cellulose (BC) was modified using zeolitic imidazolate framework 67 (ZIF67) with cobalt as the metal center, and the ZIF67/BC electrode was synthesized through stirring at room temperature. In ZIF67/BC, electrons can be transported via hopping between cobalt ions as well as via bridging through organic ligands to form a conductive network. The electrochemical performance of ZIF67/BC was evaluated using electrochemical testing, and the application potential of the electrode for detecting dibutyl phthalate (DBP) was assessed. The electrochemical redox peak current of the ZIF67/BC electrode material reached 406.1 μA, exhibiting good electrical conductivity. Additionally, the π-π stacking interaction between ZIF67 and DBP serves as a signal response mechanism to affect electron transfer. The electrochemical sensor demonstrated a linear detection range of 0–10 μM for DBP, with a detection limit of 36.63 nM and a recovery rate of 92.49%–109.57%. This study will contribute to the advancement of environmentally friendly flexible electronic devices.
