研究了颗粒表面电荷密度对静电稳定二氧化硅胶体和聚合物乳胶分散体固液相变的影响。随着电荷密度的增加，两种体系都表现出可重入跃迁。这不能用汤川势和电荷重整模型来解释。
The influence of the particle surface charge density on the solid-liquid phase transition in electrostatically stabilized colloidal silica and polymer latex dispersions is examined. Both systems show a reentrant transition with increasing charge density. This is not explainable in terms of the Yukawa potential and the charge-renormalization model.
