The authors have studied the tensio-active properties of acrylate diesters at the oil-water interface. Measurements of the interfacial tension indicate that the molecules are subsequently adsorbed at the interface. The amphiphatic compounds in the monolayer can be polymerized and cross-linked by UV irradiation. The gelation process of the two-dimensional system has been studied by measuring the shear mechanical properties. The authors observed a clear transition from a viscous solution to a cross-linked gel state. The two-dimensional films behave like rubber elastic systems. The elasticity depends strongly on the concentration of the cross-linking agent. The polymerisation of mixed films of monoacrylates and diacrylates can be used to build up two-dimensional structures with defined rheological properties.
