At the start of this project, the possible choices of metal soaps had already been narrowed to include some of the zinc soaps used in this project. These zinc soaps are mixtures of zinc stearate and zinc palmitate of varying ratios purchased from a supplier. Zinc soap was chosen as result of its common use in various industries as a lubricant and mold release, which implied potential benefits in an electrophotographic printing system. These potential benefits include, but are not limited to, a more efficient transfer from a photoconductive drum and protection of the drum from mechanical and chemical degradation. Nanoindentation of these soaps was implemented in an effort to characterize each soap mixture and compare how the soap types differed from one another. Each sample was indented under a variety of different maximum loads and at different holding times to observe effects on the modulus, hardness, and, creep. The mechanical properties measured were then used to help distinguish differences between each type and provide an insight as to how or why one mixture may be preferable over another. The data could be utilized in conjunction with further testing to be used in a simulation of an interface of interest.
