利用共混法合成了聚乙二醇-介孔二氧化硅有机-无机复合材料.采用XRD、N_2吸附-脱附、SEM、TEM、红外光谱(FTIR)、DSC-TG等对聚乙二醇-介孔二氧化硅复合材料进行了表征.结果表明,聚乙二醇-介孔二氧化硅仍保持了原来的介孔结构,可以均匀地分散到介孔二氧化硅的基质中.PEG是靠氢键吸附在纳米HMS颗粒表面,两者并没有发生化学反应生成新的化合物.所合成的聚合物具有比较好的耐温性能, HMS提高了聚合物的耐热性.
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.
