“…In addition, ZIF-8 has large specific surface area, high porosity and a large number of active sites (Zn metal sites and 2-methylimidazole organic ligands) [47,48]. So strong electrostatic interaction occurs when ZIF-8 comes into contact with acetone gas [49]. Acetone molecules are easily adsorbed in the pores of ZIF-8, thus affecting the dielectric constant of the whole gas sensing layer ZIF-8/PAN NM.…”

Znic-based metal-organic framework materials (ZIF-8) show great potential and excellent performance in the fields of sensing and catalysis. However, powdered MOF makes it easy to lose in the process of application. Herein, we use a simple blending electrostatic spinning method to combine ZIF-8 particles with polyacrylonitrile (PAN) nanofibers. ZIF-8/PAN composite nanofiber membrane. The ZIF-8/PAN nanofiber membrane is characterized by SEM, XRD, FTIR and N2 adsorption-desorption. The results show that the ZIF-8/PAN nanofiber membrane has the characteristic peaks of XRD and FTIR, which are consistent with those of simulated ZIF-8. The specific surface area of ZIF-8/PAN nanofiber membrane increases from 13.5371 m2/g to 711.4171 m2/g due to the introduction of ZIF-8 particles. The sensor using the nanofiber membrane as the gas sensing layer shows good response and linear correlation to different concentrations of acetone gas. The minimum detection limit of the sensor for acetone is 51.9 ppm. The blank control shows that the response of the sensor to acetone is mainly due to the introduction of ZIF-8 particles. In addition, the sensor also shows a good cyclic response to acetone.
