摘要：

Two array fashions (hexagonal and square) of P(St-MMA-AA) monodispersed copolymer latex particles and two packing modes (hexagonal and face centered cubic) of the colloidal crystals formed by deposition of the particles on an inclined substrate were studied. The scanning electron microscopic observation for the formed crystals verified that the square array in the formation of colloidal crystals is closely related to the temperature and surface tension of the liquid in which the colloidal crystal forms. The influence of the conditions such as temperature and surfactant on the array fashion of the particles as well as on the packing modes of the crystals has been investigated.
