The Mono- and Multi-Layer Behaviors of 2,4-HDDA Doped with Stearic Acid Including in situ Polymerization

The properties of the mono- and multi-layer of 2,4-HDDA doped with stearic acid including in-situ UV-polymerization were investigated by studying surface pressures(i.e., film miscibility in mixed monolayers) and its transferability onto the substrate(i.e., interactions and film depositions in mixed monolayers). The collapse pressure of monolayers increased in proportion to the amount of SA. For the polymerized monolayer, the isotherms showed only a single inflection point of the surface pressure. For the undoped case it was hard to prepare multilayer, but the transferability was much enhanced by doping SA.
