| 제목 | Developments of the sensing electrode for organic solvent leak sensor using graphene nanopowder |
| 초록 | Methyl ethyl ketone (MEK), methanol, toluene, xylene, dichloroethylene, dichloroethane, acetone, dichlorobenzene, methyl acetate, chlorobenzene, chloroform, etc are organic solvents. All of them are environmental pollutants and harmful to humans. But it is an extremely needful material for manufacturing industry. So, the organic solvent treatment facility requires a sensor that can determine whether or not the organic solvent leaks. In this study, the sensing electrode of organic solvent leak sensor was fabricated through the different porosity by addition of graphene nanopowders into a polytetrafluoroethylene. This electrode has displayed to be both conductive and hydrophobic conditions, it has also been shown to interact with a variety of organic molecules and perform as a sensor for their presence. The electrical conductivity of the electrode decreases rapidly upon exposure to hydrocarbons, with half-lives typically measured in seconds. It was found that the response times vary systematically within each class of hydrocarbons tested, offering the possibility of determining composition. A conductivity-based sensor was developed and optimized for the presence of liquid phase hydrocarbons. Poly Fluid leak detection represents a problem that has attracted the interest of researchers. Indeed, in water or gas supplies, chemical or thermal plants, sea-lines or cooling/heating systems leakage rates can cause important economic losses and sometimes. |
