摘要
Abstract
Polyphosphazene/carbon nanotubes(SWNTs)composites were prepared by using a solution-blending meth-od.SWNTs were randomly distributed on the polyphosphazene matrix to form a conductive phase.The structure and properties of the as-prepared composites were characterized by using Fourier-transform infrared spectrometer,scanning electron microscope,thermogravimetric analyzer,electrical conductivity tester,and vector network analyzer.The re-sults indicated that the electromagnetic shielding effectiveness and electrical conductivity of polyphosphazene/carbon nanotubes composites were related to the loading of carbon nanotubes in the matrix.The electromagnetic shielding effec-tiveness of the composites reached 60.9 dB at a SWNTs content of 15 wt%,its average electrical conductivity reached 0.989 4 S/cm,and its residual char yield was 35.66 wt%at 700℃.关键词
