This report builds upon the independent study report submitted in Fall 2022. The objective of this study was to investigate the electric charges on water droplets when submerged in different oils, including, but not limited to, Krytox 104, 105, and silicon oil, to determine the effects of the oil composition on the polarity and intensity of electromagnetic charges of the droplets. Such investigation helps interpreting some previous observations in the Weisensee lab and has the potential to enable contactless water droplet manipulation on lubricant-infused surfaces (LISs). On a personal level, the objective of this independent study was to expand my knowledge on triboelectric charging of droplets and to learn to perform experiments in a professional environment.
