제목 Synthesis Nanoparticles of Polythiophene in the Supercritical Process
초록 Abstract Polythiophene nanoparticles were synthesized by oxidation polymerization in the supercritical CO2 as an alternative solvent for polymerization medium. The polymerization in supercritical CO2 has several advantages. it can make the reaction rate faster because supercritical fluid is six times higher enthalpy more than liquid phase. The control of high temperature is also easy because it is closed system. Because boiling point of thiophene monomer is 84℃, the temperature over boiling point can’t be applied to solution polymerization. Photoemission property of PT/MeOH solution is occur at 350~370nm wavelength. From SEM analysis, particle size of polythiophene was determined to be about 800nm. Oxidation polymerization in the supercritical process is raising expected to noble method by polymerization of polythiophene and applies polymeric methodology for optical and conductive polymers.
