摘要:

The ordering of polystyrene colloidal particles floating on the surface of glycol film, forming a two-dimensional system,was studied via an optical microscope. We have observed that the interfacial colloidal particles crystallized to form a two-dimensional triangular lattice with lots of point defects and grain boundaries. The interactions between the interfacial colloidal particles are also analyzed.
