Synthesis and Characterization of Polyethy Leneglycol-mesoporous Silica Composites

Abstract

Abstract: Polyethy leneglycol-mesoporous silica was synthesized successfully using impregnation method.The samples were characterized by XRD,N_2 ab-desorption,SEM、infrared spectroscopy(FTIR),DSC-TG. The results of XRD demonstrated that polyethy leneglycol-Mesoporous silica composites kept mesostructure. The results of SEM showed that Polyethy leneglycol-mesoporous silica can be dispersed into mesoporous silical material. The infrared adsorption spectrum analysis showed that the adsorption between the polyethylene glycol and HMS was formed by hydrogen bonding, between which no chemical reactions occurred. From the TG analysis can be seen that the polymer has good heat resistance, HMS enhanced the heat-resistant of the polymer.

Key words: impregnation method;polyethy leneglycol;mesoporous silica
