제목 Iron Oxyhydroxide Nanoneedle Decoarated Hybrid Polypyrrole Nanoparicles for Chemical Nerve Gas Agent Sensing
초록 Multidimensional FeOOH nanoneedle-decorated hybrid polypyrrole nanoparticles (PFFs) were fabricated using dual-nozzle electrospray and heat stirring process. To decorate metal oxide nanoneedles on the polypyrrole (PPy) surface, metal oxide particle-decorated PPys (E_PPy) were fabricated as starting materials. The E_PPy particles were prepared by dual-nozzle electrospray in the NaOH contained collector solution. Multidimensional hybrid PFFs were then formed by heat stirring reaction in the aqueous metal precursor contained solutions. These hybrid PPFs were applied to nerve gas agent (DMMP) chemical sensor at room temperature with excellent sensitivity. The minimum detectable level (MDL) was as low as 0.1 ppb, which is higher than that for a chemical sensor based on hybrid materials.
