In this work, we newly synthesized the core-shell nanorod composites with a single-walled carbon nanotube (SWCNT) in the core and polypyrrole (PPy)/phenyl lactic acid (PLA) shells, SWCNT@PPy@PLA doped with C4F with high sensitivity and humidity resistance via a simple one-port emulsion polymerization. And we also coated HPMC-MG/MF on polypyrrole (PPy)/phenyl lactic acid (PLA) shells, SWCNT@PPy@PLA. It was confirmed that coated HPMC-MG/MF on SWCNT@PPy@PLA and SWCNT@PPy@PLA doped with C4F were more stable when comparing the humidity stability of SWCNT@PPy@PLA and SWCNT@PPy@PLA doped with C4F, and SWCNT@PPy@PLA and coated HPMC-MG/MF on SWCNT@PPy@PLA. Finally, SWCNT@PPy@PLA core–shell nanorods, as sensing materials, showed detection at room temperature down to concentration levels as low as 100 ppb and have practical applications in the field of gas sensors, such as in environmental monitoring and clinical diagnostics.
