Hexachlorocyclophosphazene was prepared using phosphorous pentachloride and ammonium chloride as raw material, hccp was mixed with Montmorillonite which aimed to decrease MMT.'s hydrophilicity. Solid state reserve cell of Mg│reformed MMT.│polymer gel containing water│graphite was assembled, and cell performance was tested. XRD and IR results show: When mass percentage lower than 9.1%, hccp mixed with MMT to form homophase, hccp phase was observed in the mixture when percentage higher than 9.1%, for hccp specific diffraction peak appears in XRD data, and 1220cm-1 which was assigned to P=N double bond 's expand vibration appears in IR data.

合成了六氯环三磷腈,并用六氯环三磷腈与蒙脱石混合对其改性,期望能减小蒙脱石的吸水性能;组装电池Mg |改性蒙脱石|含水凝胶|石墨片,并测试电池的性能。X射线粉末衍射数据和红外光谱数据表明:蒙脱石容纳六氯环三磷腈的质量分数在4.8%-9.1%之间,可与蒙脱石形成单一物相,但混合质量分数大于9.1%时,改性蒙脱石出现六氯环三磷腈的特征衍射峰,和1220 cm-1的六氯环三磷腈P=N双键的特征伸缩振动峰,证明为蒙脱石与六氯环三磷腈的两相混合。
