“…This has led to the application of ESD for the deposition of a wide variety of nanomaterials including cells [4][5][6][7] , nanoparticles [8][9][10][11] , and polymers 3,[12][13][14] . Many of these examples include the use of ESD to incorporate active materials into electronic devices 3,8,9,11,12,14 . For example, Varga et al 11 fabricated three-dimensional Pt/CsH 2 PO 4 composites through ESD, which led to a nanostructured electrode layer with high porosity that enhanced electrochemical activity in a fuel cell system.…”

“…Compared with traditional deposition methods, ESD offers numerous advantages, including: (1) generation of monodisperse droplets and uniform deposition; (2) the micro/nano size of particles produced by spray processing makes ESD an effective method for micro/nanoscale coatings; (3) morphologies of thin films are easy to adjust by varying flow rate, applied voltage, and spray temperature; (4) the process only uses small quantities of the precursor solutions and spray material; (5) and, the spray process can be implemented in ambient environment. This has led to the application of ESD for the deposition of a wide variety of nanomaterials including cells 4 – 7 , nanoparticles 8 – 11 , and polymers 3 , 12 – 14 . Many of these examples include the use of ESD to incorporate active materials into electronic devices 3 , 8 , 9 , 11 , 12 , 14 .…”

Electrospray deposition (ESD) applies a high voltage to liquids flowing through narrow capillaries to produce monodisperse generations of droplets down to hundreds of nanometers in diameter, each carrying a small amount of the delivered solute. This deposition method has been combined with insulated stencil masks for fabricating micropatterns by spraying solutions containing nanoparticles, polymers, or biomaterials. To optimize the fabrication process for micro-coatings, a self-limiting electrospray deposition (SLED) method has recently been developed. Here, we combine SLED with a pre-existing patterned polymer film to study SLED’s fundamental behavior in a bilayer geometry. SLED has been observed when glassy insulating materials are sprayed onto conductive substrates, where a thickness-limited film forms as charge accumulates and repels the arrival of additional charged droplets. In this study, polystyrene (PS), Parylene C, and SU-8 thin films of varying thickness on silicon are utilized as insulated spraying substrates. Polyvinylpyrrolidone (PVP), a thermoplastic polymer is sprayed below its glass transition temperature (Tg) to investigate the SLED behavior on the pre-deposited insulating films. Furthermore, to examine the effects of in-plane confinement on the spray, a microhole array patterned onto the PS thin film by laser dewetting was sprayed with dyed PVP in the SLED mode. This was then extended to an unmasked electrode array showing that masked SLED and laser dewetting could be used to target microscale regions of conventionally-patterned electronics.

“…The electrospray technique uses technology that is analogous to that of electrospinning for the production of nanostructures and can be deposited onto any surface (metallic or nonmetallic). This method is used to form nanostructured nanomaterial films on the conductive electrodes/substrates of either fibers or particles using electrostatic force [281][282][283]. This nanofabrication technique is useful for scientific and industrial instruments (i.e., microelectronics, material technologies, micromachining, and nanotechnology).…”
