摘要

Abstract

The hybrid micelles of polystyrene-b-poly((

-isopropyl acrylamide)-

-(4-vinylbenzyl chloride)) block copolymer (PS-

-P(NIPAM-

-VBC)) with Prussian blue (PB) in the corona were prepared by reaction of pentacyano(4-(dimethylamino)-pyridine)ferrate (Fe-DMAP)-attached PS-

-P(NIPAM-

-VBC) with FeCl

. The formation of the PB framework inside the micelles was verified by UV-Vis

FTIR and TGA. The morphology of the hybrid micelles was studied by TEM and compared with that of the neat and Fe-DMAP-attached PS-

-P(NIPAM-

-VBC). It is found that attachment of Fe-DMAP may change the short rod-like micelles of the neat PS-

-P(NIPAM-

-VBC) into spherical ones and lead to a smaller micelle size. The morphology of the hybrid micelles may be altered or remain unchanged after formation of the PB framework

depending on the chain structure of PS-

-P(NIPAM-

-VBC) and starting concentration. The thermoresponsive behavior of different micelles was studied using DLS. It is observed that attachment of Fe-DMAP can improve the hydrophilicity of the P(NIPAM-

-VBC) block

leading to weaker hysteresis of the micelle size during the heating and cooling cycle. However

the crosslinked PB framework in the micellar corona may result in a more evident hysteresis phenomenon and blur the two-stepwise change of the micellar size with temperature.
