摘要

The copper phthalocyanine (CuPc) thin film gas sensors detect to organic acids that its detection behaviors will be affected morphology with quartz crystal microbalance (QCM) method. The amorphous structure has looser surface and finer particles; therefore, it has smaller surface area. Although it has more active sites to adsorb acid molecular, it gets smaller value of frequency change (f) than α-phase morphology. The β-phase morphology has the largest surface area, so it gets the smallest value of f. The response behavior is more rapid than recovery behavior with any morphology CuPc thin film gas sensors. The film surface of amorphous structure has more porous, it has faster response time and recovery time than other structures. The β-phase morphology can get slowest response and recovery time. The results show that the CuPc thin film gas sensors detect to organic acid behavior, for example methyl acid and ethyl acid, etc.; it was affected to its surface morphology change.
