摘要: Nous avons prepare des monocouches de Langmuir avec molecules organiques qui forment phases cristal liquide en volume. Tous les polymeres et monomeres utilises presentent le meme type structure un cœur central aromatique rigide contenant plusieurs groupes esters hydrophiles deux ou chaines aliphatiques hydrophobes. Un etalement bi-dimensionnel satisfaisant est obtenu dans la plupart cas, une augmentation monotone pression superficielle fonction concentration monocouche. Aux pressions plus fortes, l'aire minimum correspond a orientation verticale decollement certains initialement contact substrat aqueux. Dans region basses pressions, donnees experimentales tendent prouver que sont orientees parallelement l'interface
