Mesoporous inorganic particles have attracted great interests as versatile platforms for applications in catalysis, drug delivery, and energy devices due to their unique properties of mesoscopic porosity with macroscopic shape. Block copolymer (BCP)-directed self-assembly synthesizes a wide variety of inorganic mesoporous materials with tunable pore size and structure. However, the BCP-directed self-assembly approach still remains several problems in controlling the macroscopic morphologies due to the limit of meso scale size.Here we report how well-studied polymer physics can be applied to inorganic materials chemistry. We developed a new approach combining BCP self-assembly and phase behaviors in multicomponent polymer blends to synthesize mesoporous inorganic particles. Microphase separation of (BCP/inorganic precursor)-domains are occurred in macrophase-separated homopolymer majority domain. The pore orientation and particle morphologies are controlled by changing the type of homopolymer matrix. Furthermore, binary homopolymer blends with BCP and inorganic precursors lead to anisotropic morphologies of mesoporous particles. |
