초록

In the present study, we synthesize nanoporous silica using an amphiphilic block copolymer as structure-directing template in sol-gel solution. The morphology change of nanoporous silica is monitored as a function of the molar ratio between inorganic species and block copolymer by X-ray diffraction (XRD), transmission (TEM) and BET analysis. Small angle neutron scattering (SANS) technique is employed at various reaction stages during sol-gel processing and provides the detailed information on the self-organization process of the organic and inorganic species into a supramolecular organic-inorganic self-assembly. Nanoporous organic polymeric nanostructures were also synthesized using an amphiphilic block copolymer in a hydrophobic media. The effect of water on the phase structure of block copolymer micelles in the reaction mixtures was explored by SANS technique.
