We present the versatile well-controlled capsule structure with functions, which is based on the self-assembled block copolymer micelles. Charged block copolymer micelles (BCMs) can incorporate functional materials into the hydrophobic cores of the micelles in water. Charged BCMs containing hydrophobic organic dyes can be deposited in the layer-by-layer fashion with BCMs with complementary charge on both flat and colloidal substrates. Specifically, in the case of multilayer films assembled with cationic and PS-b-PAA, because of aggregation between adsorbed micelles, the size of porous domains is dependent on the charge density of corona chains, molecular weight, and the number of bilayers of BCMs. Based on the growth of multilayers, we investigated the morphology of film surface deposited with both hairy and crew-cut BCMs. Our approach highlights the potential to incorporate a range of functional materials into the assembled BCMs to yield multifunctional polymeric hollow capsules. |
