Recent research suggests that ultraviolet illumination is essential for the creation of monolayers of Undecylenic Acid Methyl Ester (UDAME), as it is believed that the UV illumination initiates the radical-chain polymerization. Samples created without UV illumination, however, also show signs of a monolayer. In this study, samples were analyzed using atomic force microscopy and X-ray reflectivity to ascertain the characteristics of the film. A two-hour dark exposure, as opposed to two-hour UV

A sample prepared with a total exposure of five minutes to UDAME also showed signs of a film, though not a monolayer. This suggests that further work is necessary to fully understand UDAME monolayer formation.
