碩士 === 逢甲大學 === 材料科學與工程學系 === 105 === This study is basically involved with four major objectives including (a) fabrication of monodispersed, narrowly size-distributed PS microspheres by dispersion polymerization as well as emulsifier-free polymerization, (b) production of photonic crystals (PhCs) of PS microspheres upon the ITO glasses via solvent evaporation self-assembly (SESA) route and electrophoretic self-assembly (EPSA) route, (c) manufacture of inverse opal structure (IOS) by thermal decomposition of PS materials after electrochemical deposition (ECD) of aluminum-doped zinc oxide (AZO) and zinc oxide (ZnO) into all the available void spaces of original ordered template of opal structure, and (d) characterization of microstructure, surface morphology and capacitance of 3-D ordered templates of PhCs after fabrication of composite electrodes of ZnO/NiO inverse opal structure. We successfully fabricated the 3-D PhCs of PS microspheres, which are of various size-distributed and well-dispersed features via both dispersion polymerization and emulsifier-free polymerization. The results indicated that under various NiO deposition times (1~ 4 min). The ZnO/NiO inverse opal structure electrode obtained at the deposition time of 2 min is associated with a specific capacitance of 43.35 F/g, of which capacitance performance can be retained up to 88% level after 1000 cycles of cyclic voltammetry test.
