Figure 8From: Gas sensing properties of conducting polymer/Au-loaded ZnO nanoparticle composite materials at room temperatureSensor response and response time. (a) Sensor response. (b) Response time versus NH3 concentration (25 to 1,000 ppm) of P3HT:unloaded ZnO NPs (4:1), P3HT:1.00 mol% Au/ZnO NPs (4:1), and pure P3HT sensors at room temperature.Back to article page
