LB膜の構造と物性

抄録

The molecular aggregation structure in a monolayer on the water surface is different from the generally accepted concept. The surface pressure- area isotherm for a monolayer represents two kinds of aggregating processes of isolated domains formed right after spreading a solution on the water surface. Formation of crystalline or amorphous monolayers depends on the subphase temperature below and above the melting point of the monolayer, respectively, being irrespective of the magnitude of surface pressure. To obtain the LB film with well organized and ordered structure, the monolayer composed of amphiphile with a larger intermolecular force has to be deposited onto the substrate at the surface pressure where the monolayer is homogeneous.
