Atomic Force Microscope observation of Langmuir film of side chain liquid crystalline polysiloxane

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