| 논문초록 | Recently, we have utilized several unique amphiphilic block copolymers as templates, such as PE-PEO, PEO-PCL, PE-PEO-PCL, and PEO-PCL-PLLA to successfully fabricate a series of mesoporous materials, for example, mesoporous silicas, mesoporous phenolic resins and mesoporous carbons by a convenient EISA method. Firstly, we took PE-PEO as model block copolymer to study the TEOS-to-template or HCl-to-template weight ratio effect during the EISA process, view from the thermal dynamic point and kinetic reason, respectively. In addition, we expended the research method to the other block copolymer systems, especially for the unusual ABC type triblock copolymers, we obtained the hierarchical mesostructure by single template. These specific mesostructures could be observed easily by small angle X-ray scattering (SAXS), transmission electron microscopy (TEM) and isotherm N2 experiment. Moreover, blending technique could also be used in the templating process during EISA, the clear method could easily control the morphology and pore size of the mesoporous materials. |
