Templating Effect of Amion Monolayers on the Formation of Anionic Clay Sheets at an Air-Water Interface

Monolayers have been reported to play a template role in the formation of minerals at interfaces. For example, the oriemted nucleation of calcite is controlled by self-assembled monolayers (SAMs) of to-terminated alkanethiols ((CH₂)_nX)^1].This presentation shows the templating effect of a Langnuir monolayer of stearic acid (SA) during the preparation a thin film of anionic clay, The work is an extension of our previous works on the formation of a hybrid film of a clay and a metal complex by the Langmuir-Blodgett (LB) method^2].
