Abstract: Scalable, bottom-up fabrication with prescribed hierarchical control down to the nanoscale or even molecular scale is a key step that needs to be achieved to carry the scientific knowledge from nano-scale experiments into real-world applications. Among the broad themes with nano-scale motifs and templates, membranes, particularly with well-controlled nanoscale pores, have enormous potential for applications as diverse as breathable protective membranes for soldiers and medical providers, water purification 1, and “blue” power generation2. Recent nanofluidic experiments with single or few nanopores in graphene, molybdenum disulfide and hexagonal boron nitride have shown unique fluidic transport properties and the potential for electrokinetic energy conversion with unprecedented power densities. 2–5 In such nanopores, the high-surface charge makes possible a diffusio-osmotic mechanism for ion-selective transport, distinct from the Donnan exclusion that is typical of conventional membranes.

In the first part of my talk, I will discuss efforts related to devising solution-based, field-directed methods for nanomanufacturing vertical boron-nitride (BNNT) and carbon (CNT) nanotube-based membranes and performances for “osmotic “blue” power generation”6–8 . Subsequently, I will introduce self-assembly of block copolymer thin-films in combination with additive manufacturing techniques of ultrasonic and electrospray deposition. Specifically, I will focus on possibilities of encoding the requisite complex macromolecular architecture, without the use of concomitantly more complex building blocks or constraints, sacrificing in part, the appeal of self-assembly as a synthesis strategy. In the final part, I will highlight the future directions of autonomous and adaptive strategies in additive manufacturing and colloidal self-assembly in the broader application themes of 3D tri-continuous solid-state battery architectures, memristor systems and implantable bioartificial kidneys.
