Abstract:
The effect of poly(ethylene glycol) (PEG) chain length on textural properties had been investigated. It is shown that mesoporous and microporous silica materials can be prepared based on PEG and TEOS. At fixed molar concentration of polymer using the PEG-1300 mesoporous silica material is formed but when increasing molecular weight to 3000 - microporous silica material. With further increasing of the molecular weight of PEG to 20000 the micropore volume and total adsorption pore volume remain almost unchanged, so starting with a specific length of the PEG macromolecule the effect of molecular weight on the texture of the formed SiO2 becomes negligible. Based on the approach taken and the results we proved the possibility of purposeful control of the texture of silica materials.
