Doping된 Poly(3-vinylperylene)의 제조 및 전기적 특성 = Preparation and Electrical Properties of Doped Poly(3-vinylperylene)

다국어 초록 (Multilingual Abstract)

Poly(3-vinylperylene) has been prepared by radical polymerization of 3-vinylperylene, and characterized by spectroscopic methods, mol. wt. determination, and differential scanning calorimetry. Doped polymers have been prepared by electrolytic polymerization of 3-vinylperylene, electrochemical doping of poly(3-vinylperylene) and chemical doping of poly(3-vinylperylene). The pendant perylenyl groups of the doped polymers were observed to contain oxidized radical cations, as identified by IR, ESR, and electronic absorption spectrum. The electrochemically-doped poly(3-vinylperylene) with doping degrees of 71∼86%, prepared by both electrochemical doping of poly(3-vinylperylene) and chemical doping of poly(3-vinylperylene), exhibited room temperature conductivities of 10??∼10⁴ S cm¹ with activation energies of 0.3∼0.4eV. The chemically-doped poly(3-vinylperylene) obtained on exposure to iodine vapor exhibited room temperature conductivity up to 10?? S cm?? with a doping degree of 32%. The electrical conduction for these polymers is of thermally activated process, which is illustrated in arrhenius plots for electrical conductivities of doped polymers.
