Abstract Scope |
Recent advances in thin film synthesis have led to widespread adoption of porous thin films. Applications such as selective membranes for microfiltration systems, encapsulation of biomedical micro/nanodevices, and thermal barrier coatings for microelectronic devices lend themselves well to the study of thin films. Further, polymer thin films can be more advantageous thantheir ceramic and metallic counterpartsfor reasons including a higher surfacearea-to-volume ratio, bioresorbance, and relatively lower costs. However, there is a dearth of information available describing the mechanical response of these materials. This work provides an exploration of the nanomechanical properties of porous polymer films produced by self-limiting electrospray deposition (SLED). This novel technique provides for facile tuning of a variety of microscopic properties of thin films of porous materials, including characteristic length scale, composition, and density, leading to high-throughput analysis that can provide insights to the macroscopic bulk analogs of these materials. |
