報告摘要🔣：The design of nanostructured materials and their corresponding morphologies has attracted intense attention. Although many technologies have been explored to fabricate nanostructured materials, templated synthesis is one of the most important approaches to fabricate nanostructured materials with precisely controlled structures and morphologies from their constituent components. Here, we aim to use the self-assembly of chiral block copolymers as an emerging and powerful tool to fabricate well-defined nanomaterials with precise control over the structural dimensions and shape, as well as over the composition and corresponding spatial arrangement. Consequently, the fabrication of well-ordered nanoporous polymers can be achieved by using the self-assembly of chiral block copolymers composed of degradable block with gyroid-forming network morphologies as templates for the syntheses of various materials with different entities. Different templated syntheses are developed for the fabrication of nanoporous polymeric, metal oxide and metallic materials. By taking advantage of the well-ordered structural characteristics of the gyroid texture, the properties and applications of 3D regular nanostructures, such as optical properties, catalytic, plasmonic and photonic behavior as well as energy storage of gyroid-forming nanostructures, are demonstrated so as to prove the design concepts of metamaterials.
