抄録

The phase-separated structures of the mixed Langmuir–Blodgett (LB) films of behenic acid and hybrid carboxylic acid (FmHnA: C_mF_2m+1C_nH_2nCOOH) are investigated by focusing on the effects of the chemical structures of the hydrophobic part of FmHnA and the subphase temperature on the size and shape of the domains. Domains at the micrometer length scale and at the nanometer length scale form when m+n ≤ 16 and m+n ≥ 18, respectively. This is explained by considering the effect of the chemical structures of FmHnA on the line tension. With an increase in subphase temperature the size of the domains increases irrespective of the size of the domains. The size of the domains affects the manner in which the domain shape changes.
