  4. 4. Mesoporous Silica Formed with Triblock Copolymers

    University dissertation from Department of Physical Chemistry, Lund University

    Author : Katarina Flodström; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysikalisk kemi; 1H NMR; TEM; SAXS; in situ; mechanism of formation; cubic Ia3d; cubic Im3m; Mesoporous; synthesis; Pluronic; SBA-16; SBA-15; hexagonal p6mm; synchrotron SAXS; Physical chemistry; amphiphilic polymers; silica;

    Abstract : The formation of highly ordered mesoporous silica materials, using PEO-PPO-PEO amphiphilic triblock copolymers (so-called Pluronics) as structure directing agents, has been studied. The materials are formed through the addition of a silica source to a polymer solution of low concentration (2.5 wt ) under acidic conditions. READ MORE
