The adsorption of a liquid crystal dopant to a surface can have a significant impact on its properties such as electro-optic response and lubrication. Both the interesting properties of fluorinated liquid crystal molecules themselves and their interaction with hydrocarbons and surfaces through, for example, the oleophobic effect make them prime candidates as dopants for surface modification through adsorption. We propose an experiment to understand the driving force behind the surface adsorption and induced structure within a mixture of bulk cyanobiphenyls at both fluorinated and non-fluorinated surfaces by neutron reflection. This would lead to a better understanding of the fundamental forces in the system and aid in the design of new systems with improved surface properties.
