Electrokinetic Properties and Surface Interaction of Nonpolar Fluorocarbon Ink

Short description

Why can we barely read a computer screen if we want to work in the sun and why is this possible with an E-reader, but only for static images? Couldn’t we make an energy-efficient screen that combines the benefits of both technologies? This is one of the questions that led to this research. In this example, the important property of an E-reader is that it is a reflective screen that reflects or absorbs ambient light based on pigment particles. In order to display changing images, millions of electrically charged pigment particles have to move through an apolar liquid. To speed this up, you want the smallest possible displacement.This requires a new construction with a much thinner liquid layer, so that physical effects close to the electrode start to play an important role. This research focuses on these physical effects between the electrode and the charged liquid. This research shows that inverse micelles, roughly the equivalent of ionic charges in polar liquids, play a crucial role in this. By adsorption to the electrode, these inverse micelles cause strong changes in the electric fields, so that the charged pigment particles, which are responsible for the gray value, behave much more complex than previously thought.roughly the equivalent of ionic charges in polar liquids, playing a crucial role in this.
