Figure 7From: Gas sensing properties of conducting polymer/Au-loaded ZnO nanoparticle composite materials at room temperatureChange in resistance. The resistance of sensors with difference ratio of P3HT:1.00 mol% Au/ZnO NPs (1:0, 1:1, 2:1, 3:1, 4:1, 1:2, and 0:1) toward 25 to 1,000 ppm NH3 at room temperature.Back to article page
