Abstract
Theoretical calculations were performed to predict how the light scattering intensity would change with changes in concentration in the gel state. The theory of light scattering was applied to a random distribution of hard spheres. The spherical particles with constant diameter were embedded in a medium having a different refractive index. The light-scattering intensities obtained as a function of concentration showed that in dilute solutions the scattered light intensity increases with concentration. However, in concentrated solution greater than 0.1 or 0.2 volume fraction, the light-scattering intensity decreases with increase in concentration.
摘要
进行了理论计算，以预测在凝胶状态下光散射强度将如何随浓度变化而改变。光散射理论应用于硬球的随机分布。将直径恒定的球形颗粒嵌入具有不同折射率的介质中。作为浓度函数获得的光散射强度表明，在稀溶液中，散射光强度随浓度增加而增加。然而，在体积分数大于0.1或0.2的浓溶液中，光散射强度随浓度增加而降低。
