The formaldehyde OTFT sensor based on the airbrushed P3HT/ZnO composite thin film

摘要：

　　The pure conducting polymer P3HT film is less sensitive to the formaldehyde (HCHO),and the pure ZnO film needs a high temperature to militate the HCHO,as a result,the P3HT/ZnO composite was fabricated on the organic thin film transistor (OTFT) by spraying to detect the HCHO at room temperature,the electrical properties and sensing properties of all the prepared OTFT devices were measured by Keithley 4200-SCS source measurement unit.What is more,the effect of different P3HT/ZnO composite masses on the response of sensors were tested,all the sensors showed a remarkable response to HCHO,and the optimized composite mass of 1.0ml was obtained.Since most detecting methods for the HCHO vapor require an high temperature,the experiments and results in this paper showed the important significance for the field of HCHO detecting.
