摘　　要：采用化学镀方法对聚氨酯泡沫进行处理，在其表面均匀包覆一层镍镀层，达到表面金属化改性的目的。分别用扫描电子显微镜（SEM）、X射线衍射仪（XRD）、红外光谱仪（IR）和热重分析仪（TG）对化学镀镍前后聚氨酯泡沫的形貌、结构及热分解行为进行了表征。结果表明：通过化学镀工艺制备的镍镀层由直径为1～2μm的颗粒组成，且呈一定的取向。化学镀镍后聚氨酯泡沫的X射线衍射强度和红外透过率都有所降低。化学镀镍前后聚氨酯泡沫的TG曲线都由两个失重阶段构成，由于化学镀后聚氨酯泡沫表面的镍镀层被氧化，因此在650～1000℃之间，其TG曲线还呈现一定的上升趋势。In order to improve its performance, Ni plating was covered on he surface f olyurethane foam by electroless plating techniques. Then morphology, structure, and thermal decomposing behavior of polyurethane foam before plating and after plating were characterized by scanning electron microscopy （SEM）, X-ray diffraction （XRD）, infrared spectrometer （IR） and thermogrametric analysis （TG）. The results showed that the Ni plating was composed by particles whose diameters were in the range of 1-2μm. Compared with. those before plating, the intensity of XRD and intensity of IR of polyurethane foam after plating were decreased. The TG curves of polyurethane foam both before plating and after plating were composed by two decomposing stages. Because Ni plating was oxidized in the range of 650-1000℃, the weight of polyurethane foam after plating was increased.
