Abstract

Surfactants in solution may associate into two dimensional aggregates (membranes) which self-organize either in liquid crystalline phases or in liquid isotropic phases made of connected bilayers. When specially designed surfactants or mixture of surfactants are used the elastic modulus of these membranes may be of the order kBT. In this case, thermal fluctuations are important and lead to interesting predictions among which the existence of undulation forces and logarithm corrections to thermodynamical properties, characteristic of fluctuations in two dimensional systems, have been observed experimentally.
