| Summary: | 碩士 === 國立臺灣大學 === 高分子科學與工程學研究所 === 92 === In this study, we synthesize of conducting/insulating di-block copolymers via anionic polymerization. In which, we use poly 1,3-cyclohexadiene as a precursor via dehydrogenation to form poly para-phenylene with conjugated structure. We use two kinds of properties of designs on insulating segments：polystyrene for nonpolar ；poly-2-vinylpyridine for polar.
With the characterizations of di-block copolymers to realize its properties. The analysis of synthesis and composition：Gel Permeation Chromatogapher（GPC）、Fourier Transform Infrared Spectrometer（FTIR）、FT-NMR. Thermogravimetric analysis（TGA） and differential scanning calorimetry（DSC） for the analysis of thermal properties. Testing for its photoelectronic properties by UV-Vis Spectrophotometer（UV）、photoluminescence（PL） and Milliohm meter.
We synthesize the conducting（PPP）/hydrophilic（P2VP） amphiphilic block copolymer, moreover, try to adhere to the nanoparticles（CdS） to turn into polymer/inorganic hybrid materials. We observe the adhesion of CdS nanoparticles with TEM.
