Induced Crystallization

To date, amphiphilic block copolymers (BCPs) containing poly(vinylidene fluoride-co-hexafluoropropene) (P(VDF-co-HFP)) copolymers are rare. At moderate content of HFP, this fluorocopolymer remains semicrystalline and is able to crystallize. Amphiphilic BCPs, containing a P(VDF-co-HFP) segment could, thus be appealing for the preparation of self-assembled block copolymer morphologies through crystallization-driven self-assembly (CDSA) in selective solvents. Here the synthesis, characterization by 1H and 19F NMR spectroscopies, GPC, TGA, DSC, and XRD; and the self-assembly behavior of a P(VDF-co-HFP)-b-PEG-b-P(VDF-co-HFP) triblock copolymer were studied. The well-defined ABA amphiphilic fluorinated triblock copolymer was self-assembled into nano-objects by varying a series of key parameters such as the solvent and the non -solvent, the self-assembly protocols, and the temperature. A large range of morphologies such as spherical, square, rectangular, fiber-like, and platelet structures with sizes ranging from a few nanometers to micrometers was obtained depending on the self-assembly protocols and solvents systems used. The temperature-induced crystallization-driven self-assembly (TI-CDSA) protocol allowed some control over the shape and size of some of the morphologies.

Assembly Behavior

Self-assembly behavior of an cationic amphiphilic triblock copolymer Q-PVBC -b-PS-b-Q-PVBC in DMF/water and DMF/methanol were studied. Well defined triblock copolymer PVBC-b-PS-b-PVBC was synthesized by RAFT polymerization and the cationic amphiphilic block copolymers Q-PVBC-b-PS-b-Q-PVBC was obtained by the quaternization of hydrophobic precursors with triethylamine. It is concluded that that selective solvents had a great effect on the self-assemble morphologies of the polymer. Comparing to the micelles treating water as the selective solvent, the aggregates using methanol were irregular spheres and had larger diameter.
