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 (Sensors, 15, 3830, 2015). The sensing electrode was fabricated through the addition of graphene nanopowders to a polytetrafluoroethylene with different porosity. This electrode was shown to be both conductive and hydrophobic, while also being able 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 observed that the response times vary systematically within each class of hydrocarbons tested, offering the possibility of determining composition (ACS Sens, 2, 757, 2017). |
