Electrospray deposition (ESD) uses strong electric fields to produce generations of monodisperse droplets from solutions and dispersions that are driven toward grounded substrates. When soft materials delivered, the behavior growing film depends on film’s ability dissipate charge, which is strongly tied its mobility for dielectric materials. Accordingly, there exist three regimes electrospray: electrowetting, charged melt, self-limiting. In self-limiting regime, it has been recently shown...

Electrospray deposition (ESD) was utilized for targeted nutrient and water delivery to the roots of lettuce plants. Compatibility ESD with solutions confirmed; however, detrimental effects electric fields/current on plant growth were observed. To overcome this, a novel approach called "Staticaponics" introduced by separating current mass transport using grounded metal mesh surrounding root zone. This combination along aeroponic hydroponic concepts shown have higher solution use efficiency...

An exploded view of a Li-ion coin cell with an electrosprayed polyimide separator deposited onto NMC electrode.

Electrospray deposition (ESD) has shown great promise for manufacturing micro- and nanostructured coatings at scale on versatile substrates with complex geometries. ESD exhibits a broad spectrum of morphologies depending upon the properties spray fluids. Among them are nanowire forests or foams obtained via in-air gelation electrospray droplets formed from methylcellulose (MC) solutions.

Electrospray deposition (ESD) is employed to produce separator membranes for coin-cell lithium-ion batteries (LIBs) using off-the-shelf polyimide (PI). The PI coatings are deposited directly onto planar NMC electrodes via self-limiting electrospray (SLED). Scanning electron microscopy (SEM), optical microscopy, and spectroscopic microreflectometry implemented in combination evaluate the porosity, thickness, morphology of sprayed films. Electrochemical performance separators analyzed...

Electrospray deposition (ESD) uses strong electric fields applied to solutions and dispersions exiting a capillary produce charged monodisperse droplets driven toward grounded targets. Self-limiting electrospray (SLED) is phenomenon in which highly directed, uniform, even 3D coatings can be achieved by trapping charge the deposited film, redirecting field lines uncoated regions of target. However, when inorganic particles are added SLED sprays, buildup required repel incoming material...

Abstract Melting gels are a class of hybrid organic-inorganic, silica-based sol-gels which solid below their glass transition temperatures, near room temperature, but show thermoplastic behavior when heated. While this phase change can be repeated multiple times, heating the gel past its consolidation typically above 130 °C, initiates an irreversible reaction that produces highly crosslinked glassy organic/inorganic materials via hydrolysis and polycondensation. This ability makes melting...
