| Abstract Scope |
Electrospray deposition is a spray coating process that utilizes a high voltage to atomize a flowing solution into charged microdroplets. These self-repulsive droplets evaporate as they travel to a target grounded substrate, depositing the solution solids. In self-limiting electrospray deposition (SLED), manipulation of the electrostatic repulsion, hydrodynamic forces, and evaporation kinetics can be employed to conformally cover complex 2D and 3D architectures. The main challenge associated with SLED is that it is only compatible with a small subset of materials. One solution is the formulation of SLED-compatible “green body” inks containing easily removable binders. Once debinded, the coatings can possess a wide range of properties. Here we consider self-assembly of different 2D materials with different proportions of sublimating and evaporating binders. This proportion changes the amount of capillary driving force during debinding, with the particle concentration dictating the free volume. The resultant final morphologies range from percolated to islanded films. |
