An analytical model is presented of the static structure factor for a colloidal dispersion with size and “charge” polydispersities. The model is based on the mean spherical approximation solution of the Ornstein-Zernike equation in a hard-sphere Yukawa fluid mixture. With the use of the model, the size- and “charge”-polydispersity effects are investigated on the structure, and characteristics of the effects are discussed.
