We report on the fabrication and characterization of homogeneous, monophasic sodium metaphosphate and polyethylene glycol hybrid composites achieved via coacervation in aqueous solution. After separation and drying, an amorphous plastic solid is formed, composed mostly of hydrated sodium phosphate moieties amalgamated with polyethylene glycol chains. These composites are largely X-ray amorphous and can contain up to 8 weight percent of polymer. Impedance spectroscopic measurements reveal DC conductivity values of 12 μS/m at room temperature, an enhancement of three orders of magnitude when compared to glassy sodium metaphosphate, and the presence of the polyethylene glycol is reflected in the equivalent circuit and ionic hopping analyses.
我们报道了通过水溶液中的凝聚作用制备均匀单相偏磷酸钠和聚乙二醇杂化复合材料及其表征。分离并干燥后，形成一种无定形塑料固体，主要由与聚乙二醇链合并的水合磷酸钠部分组成。这些复合材料在很大程度上是X射线无定形的，并且可以包含高达8重量百分比的聚合物。阻抗光谱测量显示室温下的直流电导率值为12 μS/m，与玻璃态偏磷酸钠相比提高了三个数量级，并且聚乙二醇的存在反映在等效电路和离子跳跃分析中。
