| 摘 要： | 通过生物矿化合成了聚氨酯/Ag2S纳米复合薄膜．通过傅里叶变换红外光谱研究、扫描量热法(DSC)、扫描电镜等方法研究了硫化银纳米粒子对复合薄膜物理性质的影响．用DSC 测定了复合材料的热
稳定性．通过对纳米复合材料荧光性能的研究发现薄膜对Ni(II)的存在非常敏感，少量Ni(II)离子的存在使得荧光光谱强度迅速增加．可以预测此复合薄膜可被开发成水溶液中Ni(II)的传感器．

| Abstract: | A polyurethane/silver sulfide nanocomposite film was synthesized by a biomineralization sim-ulated method. The effect of the Ag2S nanoparticles on the physical properties of the com-posite was studied by Fourier transform infrared, differential scanning calorimetry (DSC), scanning electron microscopy. The thermal stability of the composite was measured by DSC. The fluorescence emission of the nanocomposite films was found to be very sensitive to Ni(II) ions, with a small amount of Ni(II) ions making the emissions increase dramatically. The films are predicted to have the potential to be developed into excellent sensing films of Ni(II) ions in the water. |
