Herein, PS-b-P2VP-b-PEO could self-assemble to form a kind of segmented wormlike nanostructures. Two formation mechanisms were observed. Moreover, such segmented wormlike nanostructures disassembled gradually when increasing the temperature.

Assembly Behavior

In this study, we report morphological transition of ABC triblock copolymer dissolved in special solvents that were good for the A block, poor for the B block, and marginal for the C block. The aggregate structure changes from rod to vesicle, and then to spherical superaggregates by changing the hydrophobicity of block B. Chain packing in different micelles is investigated.

Multi-compartment micelles (MCMs) with segregated corona formed from a specifically-tailored linear ABC triblock copolymer can be switched “on” and “off” when sequentially treated with CO2 and N2.

We report the photocontrollable micelle–cluster transition of an ABC-type triblock copolymer in an ionic liquid (IL). Polystyrene-b-poly(ethylene oxide)-b-poly(4-phenylazobenzyl acrylamide-r-N-isopropylacrylamide) (PSt-b-PEO-b-P(AzoBnAm-r-NIPAm)) was synthesised, where PSt is IL-phobic, PEO is IL-philic, and P(AzoBnAm-r-NIPAm) is photo- and thermoresponsive in the IL. At high temperatures, the triblock copolymer forms micelles with PSt cores; furthermore, at low temperatures, micelles self-assemble into clusters induced by the aggregation of P(AzoBnAm-r-NIPAm). Under UV irradiation, the micelles form clusters at lower temperatures than that in the dark because of the change in the solubility of P(AzoBnAm-r-NIPAm) induced by photoisomerisation of the azobenzene groups, indicating that this triblock copolymer has a photocontrollable micelle–cluster transition temperature.
