CuPc/ZnO杂化材料的气敏性能研究
Study on the gas sensing properties of CuPc/ZnO hybrid materials
摘要
Abstract
In order to improve the gas sensing property of the organic semiconductor material CuPc, CuPc/ZnO hybrid materials containing different amounts of ZnO were prepared using the solution method. The prepared CuPc/ZnO hybrid materials were characterized with XRD, SEM and other instruments, while their gas sensing properties were also studied. The results show that the CuPc/ZnO hybrid material containing 10% (mass fraction) ZnO shows the best sensitivity to Cl2; Compared with CuPc, its sensitivity to Cl2 with a volume fraction of 10×10-6 increases by 179% at 175 °C which is the optimal working temperature of this material; This material also exhibits a good sensitivity to Cl2 with a lower concentration, for example, its sensitivity to Cl2 with a volume fraction of 1×10-6 is 5.3 at 175 ℃. CuPc/ZnO hybrid materials show good selectivity and response characteristics to Cl2, but their recovery time is relatively long.关键词
