Abstract
Studies of the stability properties of 2-docosylamino-5-nitropyridine monol ayers have shown that three-dimensional structures are formed from the mono layer material over a wide surface pressure region between 2 and 25 mN m(-1 ) Constant surface pressure relaxation experiments are analysed on the basi s of the nucleation growth theory. Under all conditions the experimental re sults are described by the instantaneous nucleation mechanism with edge gro wth for the 2D/3D transformation process. This is different to the progress ive nucleation so far observed for the other amphiphilic monolayers. (C) 19 99 Elsevier Science B.V. All rights reserved.
