Research on the application of preparation of conductive nanofibers on coal gas sensors

Abstract

In recent years, gas sensitivity devices with high sensitivity have been applied to develop coal mine gas sensor. What’s more, the application of electrospinning method in preparing gas sensitivity devices has drawn more and more attention. Utilizing electrospinning method, this paper prepared polyaniline nanofiber membrance, which can be used for the development of new gas sensor. The process parameters were also systemically studied. To be specific, reasonable solution parameters were explored by changing preparation condition; moreover, the impact of process parameters on polyaniline electrospun fibers was explored, thereby improving the controllability of electrospun fiber morphology; finally, the structure and conductive properties of the fiber membrane were characterized by FTIR, WARD, conductivity detection.
