Abstract Scope |
In self-limiting electrospray deposition (SLED), specific manipulation of the electrostatic repulsion, hydrodynamic forces, and evaporation kinetics can be employed to conformally cover 3D architectures or targeted microscale electrodes with microcoatings. The generated coatings are hierarchical, possessing either nanoshell or nanowire microstructure. Having demonstrated the mechanism of the self-limiting effect, we have developed the ability to incorporate materials that would be otherwise incompatible with SLED into composite coatings. In this way, we have created a wide variety of functional systems, including: (1) bioactive, (2) plasmonic, and (3) electronically-active 2D materials coatings. This approach adds these functionalities to surfaces printed through other techniques either globally or selectively, such as incorporating sensing mechanisms or enhancing electrical properties. We envision this approach as a means to decouple the serial high fidelity lithographic step or rapid printing process of architectures from their final application, eliminating barriers to the manufacturing of nanomaterial-enabled devices. |
