摘要: 通过X射线衍射、傅里叶变换红外光谱和差热分析表征聚乙二醇(PEG)/蒙脱石复合物的结构结果表明,PEG以单层或双层平卧于蒙脱石层间;PEG通过转换部分层间水进入蒙脱石层间通道内;大分子量的PEG与蒙脱石层间表面有更强的相互作用.Abstract: Polyethylene glycol(PEG)/montmorillonite composites were characterized by X-ray diffraction, Fourier transform infrared spectrum and differential thermal analysis. The results showed that there were 1 or 2 layers of PEG lying flat between the montmorillonite plates. PEG entered the lamellae by replacing part of the inter-lamellar water. Polyethylene glycol of higher molecular weight showed stronger interaction with the surface of montmorillonite plates.
