In the realm of NH3 gas-sensing applications, electrically conductive nature Ti3C2Tx MXene, adorned with surface terminations such as −O and −OH groups, renders it a compelling material. However, inherent challenges atmospheric instability selectivity in presence gas mixtures have prompted exploration innovative solutions. This work introduces strategic solution through deposition mixed-matrix membrane (MMM) composed poly(vinylidene fluoride) (PVDF) matrix zeolitic imidazolate framework-67 (ZIF-67) filler. composite acts selective filter, permitting passage specific gas, namely NH3. Leveraging hydrophobic chemically inert PVDF, MMM enhances stability by impeding water molecules from interacting MXene. Furthermore, ZIF-67 is to via acid–base interactions within zeolite group pore size. The sensor embedded filter exhibits modest 1.3% change sensing response 25 ppm compared without filter. result underscores filter's effectiveness conferring diffusivity, particularly at 35% relative humidity (RH) °C. Crucially, attributes PVDF impart heightened even amidst varying RH conditions. These results not only demonstrate effective detection but also highlight sensor's adaptability diverse environmental conditions, offering promising prospects for practical applications.
