Abstract: |
Hexadecachloro zinc phthalocyanine (ZnPcCl16) was synthesized by introducing the method of ammonium molybdate solid phase catalysis, and PANI doped with HClO4 was also synthesized according to literature, and their products and films were characterized by IR, UV-vis spectroscopy and SEM. These organic semiconductor materials were mixed at different ratios (ZnPcCl16)x(PANI)1-x (0.1≤x≤0.9) to get a hybrid compound and were made films on the Pt flat electrodes by vacuum evaporation, where the electrodes were fabricated by means of micromachining technique. The gas sensitivity of the films was investigated by exposing to Cl2, NO2 and NH3 of different concentration in order to determine the best sensitivity of the hybrid sensing materials. The result indicates that the films with x＝0.7 have a relatively good sensitivity to chlorine gas.
