제목 Universal selection rule for surfactant used in miniemulsion processes for eco-friendly and high performance polymer semiconductor devices.
초록 Commercial interest in the eco-friendly processing of polymer semiconductors is on the rise. To reduce noxious solvent use and to realize water-borne colloids of polymer semiconductors, we developed a universal and eco-friendly miniemulsion process to satisfy four essential criteria: 1) efficient emulsification for synthesizing small and uniform polymer semiconductor particles 2) efficient coalescence of particles to yield high quality thin films with low roughness and high fill-factor, 3) efficient removal of residual surfactant, and 4) high ordering of polymers within particles. We prepare polymer colloids using various anionic, cationic and nonionic surfactants and systematically analyze them to find surfactants and their colloid techniques that can satisfy all three criteria. This colloid fabrication technology is a universal method that can be applied from first-generation polythiophene derivatives to the latest donor-acceptor-based planar backbone polymers.
