| Abstract Scope |
Electrospray deposition is an advanced additive manufacturing technique that uses high voltage to create an aerosol-like spray of charged nanoparticles from a flowing solution, altering substrate surface properties. This process generates a mono-disperse distribution, uniformly coating conductive substrates. As the solvent evaporates, a solid deposit forms, enabling modifications such as enhanced hydrophobicity, conductivity, or biocompatibility. However, non-conductive materials, which cannot be directly coated, pose a limitation. To overcome this, a “universal solution” was developed, allowing electrospray to be used on non-conductive substrates. The process involves dip-coating the substrate in the universal solution to form a conductive film, enabling electrospray application. The universal solution is then removed by burning, leaving only the desired electrosprayed material on the substrate. This exploration expands the versatility of electrospray deposition for diverse materials. |
