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 f...
