| Abstract | This thesis is devoted to the development of microfluidic processes for the controlled self-assembly of quantum dot compound micelles (QDCMs). Microfluidic processes are developed to combine the constituents (cadmium sulfide quantum dots, and block copolymer stabilizing chains) with water to facilitate self-assembly of the composite particles, QDCMs, through initial phase separation, subsequent growth, and eventual quenching. Two genres of microfluidic reactors are developed. The on-chip evolution of QDCM formation and growth is resolved through fluorescence microscopy; QDCM size distributions and associated statistics are determined through off-chip analysis by transmission electron microscopy (TEM). In a flow-focusing reactor, control over the mean size of QDCMs is demonstrated through both the water concentration and the growth time (or reactor channel length). Controlled QDCM self-assembly is also demonstrated in a multiphase gas-liquid reactor. In contrast to the flow-focusing reactor, increasing the multiphase reactor channel length results in a decrease in QDCM size and polydispersity. |
