摘　　要： 以大豆分离蛋白质为反应原料,戊二醛为交联剂,与不同添加量的埃洛石复合,合成制备出弹性模量达219Pa的SPI-HNTs纳米复合凝胶材料。采用模块化智能型高级流变仪证实了埃洛石与大豆分离蛋白形成的次级网络的存在,通过对比不同埃洛石添加量对SPI-HNTs纳米复合凝胶材料流变性能的影响,发现埃洛石与大豆分离蛋白质形成的次级交联网络对纳米复合凝胶的弹性模量和损耗角正切的影响规律,通过与合成的无化学交联剂的SPI-HNTs纳米复合物对比和FT-IR分析,揭示了埃洛石与大豆分离蛋白质间的次级网络对凝胶材料的增强机理。并且探讨了不同戊二醛添加量对SPI-HNTs纳米复合凝胶材料的弹性模量和损耗角正切的变化规律。 With soy protein as reaction material,glutaraldehyde as crosslinking agent,and different additives of halloysite nanotubes were composited,the sample of nano composited gel materials obtained excellent elastic modulus over 219Pa.Modular senior rheological instrument confirmed that secondary network was formed between halloysite nanotubes and soybean protein.Through comparing the effect of different adding amount of halloysite nanotubes on rheological properties of gel materials,the impact law of secondary network on modulus and tanδ of gel materials was found.By comparing rheological properties of no chemical crosslinking compound of SPI-HNTs nano compound and FTIR analysis,the enhancement mechanism from secondary network between halloysite nanotubes and soybean protein was revealed.Finally,the change rule of elastic modulus and tanδ about different additives of glutaraldehyde on gel materials was discussed.
