A facile no-template approach for fabricating curved polystyrene (PS) nanosheets by miniemulsion polymerization technique was developed. Two essences of the high hydrophobicity of oil phase and the existence of cross-linking comonomer were found to ensure the stable curved sheet-like morphology. Here, when choosing tetradecane as the hydrophobic oil phase and divinylbenzene as cross-linker, the curved...
The structured nanoparticles of styrene (St) and butadiene (Bd) block copolymers were prepared by RAFT seeded emulsion polymerization of butadiene. It was confirmed that the block copolymers of PSt-b-P(St-co-Bd) was formed with controlled molecular weight and rather low PDI at low composition of the P(St-co-Bd) segment. With more incorporation of butadiene, the branching reaction of polybutadiene...
Modeling and simulations of nitroxide-mediated radical polymerization (NMP) in dispersed systems have been performed to elucidate what factors dictate the magnitude of the segregation effect on bimolecular termination between propagating radicals generated from alkoxyamine activation. The reduction in termination rate due to segregation cannot be predicted merely based on the average number of propagating...
