High-Quality LB Films of Artificial Dialkyl Lipid

LB films (4 monolayers) of artificial dialkyl lipid were deposited over Au evaporated films on glass substrates. The film quality was examined using the Cu decoration method and optical polarization microscopy. The defect density of the lipid film was much less than that of a monoalkyl film. Moreover, the defect density was so decreased after thermal annealing and rinsing in an alcohol solution that LB films which were almost defect-free were obtained. Microscopic observation revealed a snowflake crystalline pattern after the annealing and rinsing treatments.
