英文摘要: The project aims at the ionic liquid-assisted controlled synthesis of poly(9,9-dioctylfluorene) in droplet-based microreactors. A mathematical model for droplet formation and size prediction will be proposed based on the force-balance model. Based on a defined screening criteria, a series of functional ionic liquids will be designed to investigate the effect of ionic liquids' structure and basic properties on the synthesis of poly(9,9-dioctylfluorene). The influences of experimental conditions on the controlled synthesis of poly(9,9-dioctylfluorene) and reaction kinetics will also be studied. A mathematical model for droplet-based microreactor will be established and mathematical expressions for molecular parameters will be provided. The project will provide important technical supports for the controlled synthesis of poly(9,9-dioctylfluorene) and other conducting polymers, and be a solid base for continuous synthesis of conducting polymers at the kg/day level. The project is of significant academic values and promising prospects.
