Flexible, Disposable, and Selective Sensors using ZnO Nanocomposite Barrier for Acid Leakage Detection |
| 초록 |
This paper reports on disposable leakage sensors for the acidic solution based on the composite of ZnO nanoparticle(ZnO NP) and polyurethane(PU). ZnO NP is etched only in acidic solutions and is useful for detecting acidic solutions. Using this phenomenon, the ZnO/PU nanocomposites were coated on carbon-based resistance-type sensors as a barrier. For sensitive detection of acidic solutions from sensors, oxidized multi-walled carbon nanotubes(Ox-MWNTs) were adopted as active layers, and the active layer of the sensor was selectively patterned by drop-casting Ox-MWNTs solution on ultraviolet ozone-treated substrates. Barrier films were also optimized by changing the coating conditions of the ZnO/PU nanocomposites for fast response speed and accurate detection of the sensor, and as a result, the disposable leakage sensor using the barrier film of the ZnO/PU nanocomposite for the acid solution showed good selectivity and reproducibility. |
