摘要: Poly(3,4-ethylenedioxythiophene) nanotubes (PEDOT NTs) flexible membrane was successfully fabricated by vapor deposition polymerization (VDP) mediated electrospinning for ammonia gas detection. PVA nanofibers (NFs) were electrospun as a core part and polyvinyl alcohol (PVA)/PEDOT coaxial nanocables (NCs) prepared VDP method via EDOT monomer adsorption onto the NFs templates. To obtain PEDOT NTs membrane, removed from PVA/PEDOT NCs with distilled water. had conductivities of 71 61 Scm(-1) applied transducer detection in range 1-100 parts per million (ppm) NH(3) gas. They exhibited minimum detectable level ca. 5 fast response time (less than 1s) towards In recovery time, sensor 30s shorter compared to that based on (ca. 50s). addition, performance also undertaken function thickness. Thick (30 microm) enhanced sensitivity thickness order 30 microm>20 microm>10 microm at 60 ppm
