摘　　要：以改性聚丙烯酰胺、甲苯二异氰酸酯和聚醚多元醇为主要原料,采用一步发泡法,制备具有酰胺基(-NHCO-)的聚氨酯功能泡塑,并利用扫描电子显微镜(SEM)、傅里叶变换红外光谱仪(FT-IR)等对其性能进行表征。用该泡塑对溶菌酶/牛血清白蛋白混合液进行分离,通过SDS-PAGE电泳对其分离效果进行检测。结果表明,当制备泡塑的原料质量比为m(聚醚)∶m(甲苯二异氰酸酯)∶m(聚丙烯酰胺)∶m(丙酮)∶m(三乙烯二胺)∶m(二丁基二月桂酸锡)∶m(硅油)∶m(水)=100∶150∶25∶20∶0.6∶0.4∶1∶0.1时,合成的泡塑孔隙率高,孔泡均匀,内外孔连通,溶胀度为18%,溶损率为0.036%,且具有功能基团酰胺基,对混合蛋白液具有良好的分离效果。Abstract： A kind of functional polyurethane foam was prepared by means of modified PAM, TD1 and polyether ~ main materials by one step bubble method. The production was characterized by scanning electron microsco ,DS（SEM）and Fourier transform infrared spectroscopy（FT IR）. The foam was used to separate the proteins mixure （l,ys and BSA）. The results showed that when the formula of functional polyurethane foam is as folows： the mass ratio among polyether, TDI, PAM, acetone, TEDA, DBTDL, Si and H2O, is 100：150 ： 25 ： 20 ： 0.6 ： 0.4 ： 1 ： 0.1, the foam＇s swelling capacity and the solution-loss rate in water is measured to be 18% and 0.036% respectively. The foam has acylamide, and can separate the mixed proteins well. Key words, functional polyurethane foam; acylamide; protein
