The objective of this independent study is to investigate the electric charges on water droplets when submerged in different lubricants including, but not limited to, Krytox 104, 105, and silicon oil, to determine the effects of lubricant oils 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 on LISs and to learn to perform experiments in a professional environment.
