Comparative Studies on Shape-Controlled Polyaniline Nanomaterials for DMMP Detection |
| 초록 |
Along with the increasing threat of chemical terrorism, there has been a growing interest in highly sensitive chemical sensors that can detect toxic gases at very low concentrations. High-performance chemiresistive sensors using PANI nanomaterials were successfully fabricated and their sensing properties were demonstrated. The charge-transport properties of the precisely controlled PANI geometries at the nanometer scale were systematically investigated to identify the optimal sensing conditions to detect the nerve gas agent dimethyl methylphosphonate (DMMP). The real-time response from a DMMP-sensor based on PANI nanofibers was better than those for sensors made with PANI nanoparticles or nanorods. High-performance chemiresistive sensors with a low minimum detection level (MDL, 5 ppb) could be designed through comparative studies of charge-transport properties. |
