激光散射可用于探测包括胶体、凝胶、乳液和囊泡在内的各种系统的结构和动力学。 小的长度尺度结构,如界面、浓度或密度波动,导致折射率的变化,这反过来又散射光。通过分析从材料散射的光的时间依赖性和在不同方向上散射的光的强度,可以测量各种有用的材料特性。 在颗粒分散体中,这些性质包括粒度、分子量、流动性和颗粒间相互作用的强度,而在凝胶和其他更连续的系统中,性质包括形态和粘弹性模量。
英文摘要
Laser light scattering can be used to probe the structure and dynamics of a wide range of systems including colloids, gels, emulsions and vesicles. Small length scale structures, such as interfaces, concentration or density fluctuations, result in variations in the index of refraction which, in turn, scatter light. By analyzing the time dependence of light scattered from a material and the intensity of light scattered in different directions, a variety of useful material properties can be measured. In particle dispersions, such properties include particle size, molecular weight, mobility and the strength of interparticle interactions, while in gels and other more continuous systems properties include morphology and viscoelastic moduli.
