Based on the PEG (polyethylene glycol)’s function of bridging flocculation and the MC (methyl cellulose)’s function of formation of liquid crystal in aqueous solution, the morphology of micrometer-sized mesoporous silica spheres with good dispersivity were synthesized by adding the mixture of PEG and MC into the aqueous solution containing F127 and TEOS. It was found that only when PEG was added,...
This paper presents the integrated results of a series of new methods for preparing mesoporous silica spheres as high-performance liquid chromatography (HPLC) packing materials. The separation performance of the mesoporous spheres materials has also been determined. Micrometer-sized silica spheres with uniform spherical morphologies and ordered mesostructures were first successfully synthesized by...
