Non-Linear Modeling of the Dynamic Response of Single-Wall Carbon Nanotube SWNT Composites to NO2 Gas in Air

Article Preview

Abstract:

The objective of this study is to develop a mathematical model, which can describe the response of a single-wall carbon nanotube (SWNT) as a resistive NO2 sensor, based on the acquired experimental data. The obtained non-linear regression attempts to simulate and predict the sensor response taking into account the effect of different variables such as NO2 concentration and operating temperature. The results show that the developed mathematical equation expresses the sensor response as a function of time, gas concentration, and temperature with an R-squared value ranging between 0.65 and 0.97.
