Abstract

Solution-processed two-dimensional (2D) nanoelectronic materials are promising inks for printed applications including flexible electronics, batteries, and sensors. However, the polydisperse nature of nanomaterial dispersions following liquid-phase exfoliation poses manufacturing challenges since incompletely exfoliated materials must be removed to achieve optimal properties. Incumbent separation schemes invariably rely on centrifugation, which is highly energy-intensive and limits scalable manufacturing. In contrast, this talk will explore cross-flow filtration (CFF) as a centrifuge-free processing method that improves the throughput of nanomaterial separations by orders of magnitude [1]. By tuning membrane pore sizes between microfiltration and ultrafiltration, CFF can also be used for efficient recovery of solvents and stabilizing polymers [2]. Further sustainability gains can be achieved by employing bio-derived cellulosic stabilizers and graphite in place of synthetic analogues [3]. In this manner, life cycle assessment and techno-economic analysis reveal that the combination of CFF processing and bio-renewable raw materials leads to significant reductions in greenhouse gas emissions, fossil energy usage, water consumption, and specific production costs. To confirm that CFF produces electronic-grade nanomaterials, the performance of sustainably produced 2D nanoelectronic inks in printed electronic, optoelectronic, and energy technologies will be delineated including photodetectors, optical emitters, supercapacitors, and batteries [4-7].
