PEG/VXG纳米复合材料的新研制方法

New Method for Preparation of PEG/VXG Nanocomposite

介绍了一种新的制备聚合物 /无机层状化合物纳米复合材料的方法 ,即用多钒酸作引发剂 ,在制备五氧化二钒干凝胶的同时 ,将聚乙二醇嵌入到五氧化二钒的层状结构中去 ,该方法简单实用 ,而且可以通过控制聚乙二醇的量来控制纳米复合材料的层间距 ,为更好地了解和控制纳米复合材料的界面结构提供了一条新思路。实验表明 ,PEG/VXG纳米复合材料保持了 VXG的层状结构 ,同时增加了三维方向的有序性 ,且随着 PEG含量的增大 。

A new method for preparation of PEG/VXG nanocomposite was introduced Using decavanadic acid as initiator, PEG was intercalating into the layers of V 2O 5 while VXG was forming The layered distance can be controlled by the content of PEG This is a new idea for studing the interface of nanocomposite The experiment shows that PEG/VXG nanocomposite keeps the layer structure of VXG and increases the layered distance but decreases the ordered zone
