摘　　要：采用溶液共混和液-固相转变法(L-S)制备了用于高效液相色谱(HPLC)柱填料的共聚尼龙/醋酸纤维素共混物(PA-130/CA)。以小分子量化合物为探针分子,用HPLC数据表征了PA-130/CA合金膜材料的界面性能,并研究了其合金膜材料的相容性和热稳定性。结果表明:PA-130与CA有很好的相容性;该合金膜的热稳定性比纯CA膜的有所提高;质量比为30/70的PA-130/CA合金膜对不离解极性有机物的分离效率更高。The copolyamide（PA-130）/cellulose acetate （CA） blends were prepared by means of solution blending and liquid-solid phase transformation （L-S）as column packing material of high performance liquid chromatography（HPLC）, and small molecular weight compound as probe molecule was employed. The interracial properties of PA-130/CA alloy membrane materials were characterized by HPLC. The compatibility and thermal stability of the alloy membrane materials were studied. The results indicate that there is good compatibility between PA-130 and CA. The thermal stability of the alloy membrane materials is improved. The PA-130/CA alloy membrane material （30/70） is optimal in the separation efficiency for non-dissociable polar organic solute.
