Abstract: Some variations provide a device for assembling a plurality of particles into particle assemblies, comprising: (a) a microfluidic droplet-generating region; (b) a first inlet to the droplet-generating region, configured to feed a first fluid containing particles and a solvent for the particles; (c) a second inlet to the droplet-generating region, configured to feed a second fluid that is not fully miscible with the first fluid; (d) a droplet outlet from the droplet-generating region, configured to withdraw droplets of the first fluid dispersed in the second fluid; and (e) a droplet-dissolving region configured to remove solvent from the droplets, thereby forming particle assemblies. Some variations also provide an assembly of nanoparticles, wherein the assembly has a volume from 1 micron3? to 1 mm3?, a packing fraction from 20% to 100%, and/or an average relative surface roughness less than 1%, wherein the assembly is not disposed on a substrate.

Abstract: This disclosure describes incorporation of a liquid additive within one or more phases of a multiphase polymer coating. The structure of the microphase-separated network provides reservoirs for liquid in discrete and/or continuous phases. Some variations provide an anti-fouling segmented copolymer composition comprising: (a) one or more first soft segments selected from fluoropolymers; (b) one or more second soft segments selected from polyesters or polyethers; (c) one or more isocyanate species; (d) one or more polyol or polyamine chain extenders or crosslinkers; and (e) a liquid additive disposed in the first soft segments and/or the second soft segments. The first soft segments and the second soft segments are microphase-separated on a microphase-separation length scale from 0.1 microns to 500 microns. These solid/liquid hybrid materials improve physical properties associated with the coating in applications such as anti-fouling (e.g., anti-ice or anti-bug) surfaces, ion conduction, and corrosion resistance.

Abstract: Some variations provide a low-adhesion coating comprising a continuous matrix containing a first component, a plurality of inclusions containing a second component, and a solid-state lubricant distributed within the coating, wherein one of the first component or the second component is a low-surface-energy polymer, and the other of the first component or the second component is a hygroscopic material. The solid-state lubricant may be selected from graphite, graphene, molybdenum disulfide, tungsten disulfide, hexagonal boron nitride, or poly(tetrafluoroethylene) or other fluoropolymers. The solid-state lubricant particles may be coated with a metal selected from cadmium, lead, tin, zinc, copper, nickel, or alloys containing one or more of these metals. The solid-state lubricant is typically characterized by an average particle size from about 0.1 microns to about 500 microns. The solid-state lubricant is preferably distributed throughout the coating.

Abstract: Durable, impact-resistant structural coatings with dewetting and anti-icing properties are disclosed. The coatings possess a self-similar structure with two feature sizes that are tuned to affect the wetting of water and freezing of water on the surface. Dewetting and anti-icing performance is simultaneously achieved in a structural coating comprising multiple layers, with each layer including (a) a continuous matrix; (b) porous voids, dispersed within the matrix, to inhibit wetting of water; and (c) nanoparticles, on pore surfaces, that inhibit heterogeneous nucleation of water. These structural coatings utilize low-cost and lightweight materials that can be rapidly sprayed over large areas. If the surface is damaged during use, fresh material will expose a coating surface that is identical to that which was removed, for extended lifetime.
