项目摘要
Dynamic light scattering measurement after shearing the lamellar/sponge coexisting phase reveals that the connected membranes in the lamellar phase significantly influence the viscoelastic behavior of the lamellar phase.Viscoelasticity of vesicle phase made of DMPG lipid systems shows a significant hysteresis in heating and cooling cycle. This temperature dependence can be attributed to the deformability of vesicles. It is found that the highly deformable vesicle shows the shear-thickening behavior, which indicates non-equilibrium phase transition.We designed a diffusive wave spectroscopy apparatus equipped with shear cell. Our apparatus allows measuring the microrheology of non-equilibrium phase induced by shear. We also tried to achieve the microrheology measurement via the dynamic light scattering. Unfortunately, we found that the mircrorheology via the DLS is not yet applicable for the viscoelastic materials because of the appearance of the wavelength dependence of the mean square distance of the probe particle.
剪切片层/海绵共存相后的动态光散射测量表明,片层相中的连接膜对片层相的粘弹性行为有显著影响。DMPG脂质体系的囊泡相粘弹性在加热和冷却循环中表现出明显的滞后性。这种温度依赖性可归因于囊泡的可变形性。发现高变形囊泡表现出剪切增厚行为,表明非平衡相变。设计了一种带有剪切细胞的扩散波谱仪。我们的仪器可以测量由剪切引起的非平衡相的微流变学。我们还尝试通过动态光散射来实现微流变学测量。不幸的是,我们发现通过DLS的微流变学还不适用于粘弹性材料,因为探针粒子的均方距离的波长依赖性的出现。
