摘　　要：使用双丙酮丙烯酰胺(DAAM)为交联单体,以氧化石墨烯(GO)对酪素进行接枝改性,得到了力学性能好,耐湿擦等级高的改性酪素。探讨了GO用量对酪素改性效果的影响。采用FT-IR和AFM对制备的GO进行了表证,表明制得的GO富有含氧基团(C=O、-OH、-COOH、C-O-C等)且具有较好的稳定性;力学性能测试表明,当DAAM用量为30%、GO用量为0.5%时,改性酪素的拉伸强度、断裂伸长率以及耐湿擦性能均达到最优。The modified casein with good mechanical properties and high grade wet rub tastness was prepared by using diaeetone acrylamide （DAAM） as a crosslinking monomer and graphene oxide （GO） as an additive, and the influence of GO dosage on performances of the modified casein was discussed. The results indicated that a lot of oxygen-containing groups existed in GO molecular structure and GO dispersion had a good stability. The results of mechanical property test show that the optimal tensile strength, elongation at break and wet rub resistance are obtained when the DAAM dosage is 30% and GO is 0.5%
