A research team has developed what they call a dip-and-peel strategy for simple and rapid fabrication of two-dimensional ionogel membranes. By dipping sustainable biomass materials in certain solvents, molecules naturally respond by arranging themselves into functional thin films at the edge of the material that can easily be removed using nothing more than a simple set of tweezers.
A typical chemical reaction that most people have observed is the basis for a novel method of producing a flexible gel film that could lead to advancements in sensors, batteries, robotics, and other areas.
