Polymer composite coatings lend themselves to a multitude of advanced engineering applications. From catalysis and biosensors to battery separation membranes and nanofiltration devices for wastewater treatment, polymer films offer numerous benefits for these types of application. The ability to generate porous high surface area-to-volume, light weight, yet mechanically robust films has traditionally been limited to phase inversion for free standing films and roll-to-roll techniques for supported films. These methods are often reproducible and low cost but are mostly limited to 2D planar surfaces. In this work, electrospray deposition (ESD) is used to fabricate porous polymer composite films with tunable microstructures and mechanical properties across a broad range of deformation regimes and strain rates. The structure of this review is as follows: (1) A review of ESD and self-limiting electrospray deposition (SLED) is provided. (2) Experimental parameters and materials used in each chapter are defined. (3) Self-limiting ability of co-polymer compositions are evaluated and characterized mechanically, and limitations are discussed. (4) Various mechanical models are explored, and the structure-property relationships across various strain rates are analyzed using quartz crystal microbalance with dissipation (QCM-D). (5) ESD of polyimide (PI) is conducted to fabricate Li-ion battery (LIB) separators in coin-cell batteries, and their electrochemical performance are evaluated (6) Enhancements to the tunability of SLED films are explored including (a) addition of ionic charge carriers to obtain nanoparticles and (b) co-solvent blending to control film thickness and porosity. (7) Finally, this work concludes with the assessment of relevant applications to solid state batteries (SSBs) and an outlook for future research.
