碩士 === 國立臺灣科技大學 === 纖維工程技術系 === 82 === This thesis discusses the synthesis of Matal phthalocyanine sheet polymers were prepared by the reaction of 3,3',4,4'-benzophenonetetracarboxylic dianhydride , metal ( Co, Cu and Zn ) salt,urea and catalyst at 150∼250℃.UV/VIS spectrum,IR spectrum , elemetal analysis , X-ray diffraction , theral analysis(TGA and DTG) and conductivity measurement were carried out for the characterization. There materials have green or deep blue color and only soluble in sulfuric acide.The UV/VIS spectrum shows three or four peaks.X-ray diffraction shows two peaks and amorphous, The elemetal analysis indicated 10∼30 degree of polymization were occured, the TGA studies inducate exellent thermal stability in nitrogen atmosphere and thermal oxidative stability in air. At last the conductivity measurements show that conductivities are about 10-9 Ω-1 cm-1 at room temperature and increase conductivity from 10-9 Ω-1 cm-1 to 10-6 Ω-1 cm-1 with temperature. These results indicate that these materials are semiconductor in nature.
