The self-assembly of BCPs is mainly controlled by the monomer–monomer interactions, block compositions and molecular architectures. Also, placing BCPs under confinement attracts people’s attention because of their diversity of self-assembled morphologies. Here we use cylinder-forming PS-PLLA BCPs as a model system to study their self-assembly behaviors in a 3D confinement. Polymeric and ceramic inverse opals are served as templates for the 3D confinement. PUA and SiO2 inverse opals are used for the polymeric and ceramic 3D confinement structure, respectively. A variety of factors including hydrophilic property of template, intrinsic template property, and confinement size are performed. After hydrolysis of PLLA block, the hierarchical structure with high surface area should have great potential for filter application.
