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.

Gas Sensing Properties

Electro spinning technology combined with chemical precipitation method and high-temperature calcination was used to prepare SnO2-NiO composite semiconductor nanofibers with different Sn content. Scanning electron microscope (SEM), X-ray diffractometer (XRD) and energy dispersive X-ray spectrometer (EDS) were used to characterize the morphology, structure and content of various elements of the sample. Using ethanol as the target gas, the gas sensing properties of SnO2-NiO nanofibers and the influence of Sn content on the gas sensing properties of composite nanofibers were explored. The research results show that SnO2-NiO composite nanofibers have a three-dimensional network structure, and the SnO2 composite can significantly enhance the gas sensitivity of NiO nanofibers. With increase of SnO2 content, the response sensitivity of composite fibers to ethanol gas increases, and the response sensitivity of composite nanofibers with the highest response to ethanol gas with a volume fraction of 100×10-6 at the optimal working temperature of 160℃ are13.4;It is 8.38 times the maximum response sensitivity of NiO nanofibers. Compared with the common ethanol gas sensor MQ-3 on the market, SnO2-NiO composite nanofibers have a lower optimal working temperature and higher response sensitivity, which has certain practical application value
