The Langmuir film of a side chain liquid crystalline polysiloxane with chiral end groups at the air/water interface has been observed using Atomic Force Microscope (AFM). The domains of the polysiloxane formed at the interface and the aggregation and rearrangement process of the film have been studied. The nano-scale dispersed particles can form one-layer structure and bilayer overlapped structure in succession when compressing. The models are proposed to explain the formation, aggregation and rearrangement of these nanoscale domains of the polysiloxane liquid crystals.
