Abstract
Isotherm measurements and structural analysis of LB films have shown t hat a first-order transition appears on compression of a PLA50 monolay er. Transmission electronic microscopy and atomic force microscopy hav e revealed the coexistence of a condensed and an expanded phase. Durin g the growth of the condensed phase, we observed the formation and the fusion of submicrometer domains with an overheight limited to about 1 7 angstrom. This indicated that the expulsed lactic units associate in structured domains.
