Scanning electron microscopy,transmission electron microscopy,circular dichroism and small-angle X-ray diffraction were used to analyze the aggregation mode of CSG in the organogel phase.A hierarchical self-assembly model was proposed to explain the transition from molecular to primary and secondary structure.It is shown from our results that CSG can aggregate into a micellar fibril nanostructure with high length-to-width ratio which is bundled and entangled to form a three-dimensional(3D) network that immobilize the fluid component probably by surface tension.Moreover,sol-gel polymerization of tetraethoxysilane was carried out using CSG in the gel phase.
