SELF-ORGANIZATION OF AMPHIPHILIC N-ACYLATED LINEAR POLYETHYLENEIMINES- INVESTIGATION OF A REVERSIBLE MONOLAYER COLLAPSE

Poly-N-4-decyloxybenzoylethyleneimine, highly crystalline in bulk, for ms a stable monolayer at the air-water interface which undergoes a rev ersible collapse into a probable bilayer structure at higher surface p ressures, We achieved transfer both from the monolayer and ''bilayer'' region of the polymer film at the water surface onto hydrophilic and hydrophobized quartz supports. Based on X-ray investigations on the de posited Langmuir-Blodgett films, a possible mechanism for the reversib le collapse is proposed.
