Preparation and Ammonia Sensing Properties of PANI-TSA/PA6 Core-Shell Nanofibers by Electrospinning

Abstract

PANI-TSA/PA6 core-shell nanofibers were prepared via the electrospinning process with a PA6/formic acid solution and the chemical polymerization of PANI doped with p-toluene sulfonic acid (TSA) on the surface of the PA6 nanofibers. Their structure and morphology were examined by FE-SEM and FTIR and the fabrication mechanism and ammonia sensing properties of the PANI-TSA/PA6 nanofibers were also investigated. All the results showed that, composite nanofibers with PANI-TSA shell and PA6 core had been prepared successfully, which showed a good potential in ammonia sensitivity application.
