1 Conjugated and Ionic Block Copolymers: Synthesis, Characterization and Solid State Morphology
A series of well-defined block copolymer (BCP) consisting of a conjugated polymer segment and an ionic polymer segment will be synthesized by a combination of two controlled polymerization techniques, i.e., Grignard Metathesis (GRIM) polymerization and Atom Transfer Radical Polymerization (ATRP). The two blocks of targeted BCP are poly[3-(2-ethyl)hexylthiophene] (P3EHT) and poly(sodium 4-styrenesulfonate) (PSSNa). The block copolymer is expected to undergo microphase separation, and the morphology in solid state will be controlled by the polymer composition, processing conditions and interfacial energy (in thin film configuration). The morphology of the block copolymer in bulk and thin film configuration will be investigated. The polymer thin film with certain morphology such as lamellar and hexagonal structures can have potential uses such as Faraday effect sensor and artificial photosynthesis membrane. Lamellar structure in thin film Hexagonally packed cylinders in thin film Zhaoyuan Liu
