【摘要】 目的 :为探讨复合材料的结构及功能提供基础数据。方法 :采用X -射线衍射 (XRD)分析超声波振荡聚乙二醇(PEG) /蒙脱石 (MMT)插层复合物的结构。结果 :较大分子量的PEG与蒙脱石插层后的层间距更大。结论 :较高相对分子质量的PEG与蒙脱石层间距有较强的结合能力更多还原

【Abstract】 Objective:To supply basic data for the study of intercalated composites’ structure and functoin. Methods:Adopt XRD to analyze the structure of polyethylene glycol(PEG)/montmorillonite composites prepared by ultrasonic technology. Results:It showed that the interval-distance is larger when the molecular weight(MW) of PEG is higher. Conclusion:Higher MW of PEG has the stronger reciprocity with interbedded montmorillonite.更多还原
