摘要： Some variations provide a multiphase polymer composition comprising a first polymer material and a second polymer material that are chemically distinct, wherein the first polymer material and the second polymer material are microphase-separated on a microphase-separation length scale from about 0.1 microns to about 500 microns, wherein the multiphase polymer composition comprises first solid functional particles selectively dispersed within the first polymer material, and wherein the first solid functional particles are chemically distinct from the first polymer material and the second polymer material. Some embodiments provide an anti-corrosion composition comprising first corrosion-inhibitor particles or precursors selectively dispersed within the first polymer material, wherein the multiphase polymer composition optionally further comprises second corrosion-inhibitor particles or precursors selectively dispersed within the second polymer material. These multiphase polymer compositions may be used for other applications, such as self-cleaning, self-healing, or flame-retardant coatings. Methods of making and using these multiphase polymer compositions are disclosed.

摘要： We have demonstrated reversibly reducing metal-ion crosslinkages in polymer systems, by harnessing light, creating a dynamic and reversible bond. The reduction induces chemical and physical changes in the polymer materials. Some variations provide a polymer composition comprising: a polymer matrix containing one or more ionic species; one or more photosensitizers; and one or more metal ions capable of reversibly changing from a first oxidation state to a second oxidation state when in the presence of the photosensitizers and light. Some embodiments employ urethane-based ionomers capable of changing their crosslinked state under the influence of a change in counterion valance, using light or chemical reducing agents. This invention provides films, coatings, or objects that are reversible, re-mendable, self-healing, mechanically adjustable, and/or thermoplastic/thermoset-switchable.

摘要： This invention provides metal-foam electrodes for batteries and fuel cells. In some variations, an electrode includes a first metal layer disposed on a second metal layer, wherein the first metal layer comprises an electrically conductive, open-cell metal foam with an average cell diameter of about 25 μm or less. The structure also includes smaller pores between the cells. The electrode forms a one piece monolithic structure and allows thicker electrodes than are possible with current electrode-fabrication techniques. These electrodes are formed from an all-fluidic plating solution. The disclosed structures increase energy density in batteries and power density in fuel cells.

摘要： Thermal barrier materials are provided that possess low heat capacity and low thermal conductivity, while at the same time, high structural integrity and robustness. In some embodiments, the disclosed coating comprises metal-containing spheres that are sintered or glued together and/or embedded in a matrix. The coating has at least 60% void volume fraction and closed porosity. The coating thickness is from 50 microns to 500 microns, and the metal spheres have an average diameter that is from about 5% to about 30% of the coating thickness. In some embodiments, the metal spheres have an average diameter that is 4-10 times smaller than the coating thickness. Thermal barrier materials with these coatings can be beneficial in engine applications, for example.

摘要： Some variations provide a method of forming a transparent icephobic coating, comprising: obtaining a hardenable precursor comprising a first component and a plurality of inclusions containing a second component, wherein one of the first component or the second component is a low-surface-energy polymer, and the other is a hygroscopic material; applying mechanical shear and/or sonication to the hardenable precursor; disposing the hardenable precursor onto a substrate; and curing the hardenable precursor to form a transparent icephobic coating. The coating contains a hardened continuous matrix containing regions of the first component separated from regions of the second component on an average length scale of phase inhomogeneity from 10 nanometers to 10 microns, such as less than 1 micron, or less than 100 nanometers. The transparent icephobic coating may be characterized by a light transmittance of at least 50% at wavelengths from 400 nm to 800 nm, through a 100-micron coating.

摘要： 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.
