Surface pressure-area isotherms of Langmuir films of C-70/arachidic ac
id mixed films were measured at the water (pH=2)-air interface, at sev
eral temperatures and concentrations. Our results for the case of 25 d
egrees C and 1:1 mixtures, differ from those presented by Jehoulet, et
al. (1992), and are closer to the results for C-60/arachidic acid mix
ed films presented by those authors.
