Mesoporous Monoliths of Inverse Bicontinuous Cubic Phases of Block Copolymer Bilayers |
| 초록 |
Solution self-assembly of block copolymers into inverse bicontinuous cubic mesophases is a promising new approach for creating highly organized porous polymer films and monoliths. Here we report the direct self-assembly of block copolymers having branched hydrophilic blocks into large monoliths consisting of the inverse bicontinuous cubic structures of the block copolymer bilayer. We suggest a ficile and scalable method of solution self-assembly by diffusion of water to the block copolymer solution, which results in the unperturbed formation of mesoporous monoliths with large pore networks weaved in crystalline lattices. The surface functional groups of the internal large pore networks are freely accessible for large guest molecules such as protein complexes. The internal double-diamond networks of large pores within the mesoporous monoliths could be replicated to self-supporting 3-dimensional skeletal structures of crystalline titania and mesoporous silica. |
