Irregularities in the Synthesis of an Undecylenic Acid Methyl Ester (UDAME) Monolayer on a Silicon (111) Substrate

Public Deposited

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 illumination, showed the characteristics of a film expected from the UV treatment. 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.
