摘要：
Methods have been developed recently for the preparation of monodisperse ellipsoidal polystyrene particles which also allow the axial ratio to be varied. Electrophoretic examination of these particles raised the possibility of a nonuniform surface charge distribution. Heterocoagulation of small spherical cationic particles onto the surface of the anionic ellipsoidal particles has been used to explore this possibility. (C) 1998 Elsevier Science B.V.
