Abstract: 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.

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 preceramic resin precursor formulation comprising: first molecules comprising at least one Si—C bond and/or at least one Si—N bond, wherein the first molecules include at least one silyl hydride group (Si—H) available for hydrosilylation; and second molecules with at least one unsaturated carbon-carbon bond attached to a UV-active functional group. The first molecules and second molecules may be reacted, via hydrosilylation with a homogeneous or heterogeneous metal-containing catalyst, to produce third molecules comprising a hydrosilylation-modified polysilazane that contains the UV-active functional group. Many possible starting formulations are described, and methods are disclosed for carrying out the chemical reactions to generate the hydrosilylation-modified polysilazanes. The hydrosilylation-modified polysilazanes may then be 3D-printed and thermally treating to fabricate a ceramic material.

Abstract: An anti-fouling coating is provided, containing a continuous matrix comprising a first component; a plurality of inclusions comprising a second component, wherein the first component is a low-surface-energy polymer having a surface energy, and the second component is a hygroscopic material containing one or more ionic species. The low-surface-energy polymer and the hygroscopic material are chemically connected ionically or covalently, such as in a segmented copolymer composition comprising fluoropolymer soft segments and ionic species contained within the soft segments. The continuous matrix and the inclusions form a lubricating surface layer in the presence of humidity. Coefficient-of-friction experimental data is presented for various sample coatings. The incorporation of ionic species into the polymer chain backbone increases the hygroscopic behavior of the overall structure. Improvement in lubrication enables material to be cleared from a surface using the natural motion of an automotive or aerospace vehicle.

Abstract: 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.

The disclosed infrared-transparent polymers are low-cost, damage-resistant, and economically scalable to commercially relevant substrate areas (1 ft2 and greater). In some disclosed infrared-transparent polymers, the carbon-free polymer backbone contains a plurality of polymer repeat units of the form
wherein R1 is selected from the group consisting of alkyls, hydroxyl, amino, urea, thiol, thioether, amino alkyls, carboxylates, metals, metal-containing groups, and deuterated forms or combinations thereof; wherein R2 is (independently from R1) selected from the group consisting of alkyls, hydroxyl, amino, urea, thiol, thioether, amino alkyls, carboxylates, metals, metal-containing groups, and deuterated forms or combinations thereof; wherein n is selected from 2 to about 10,000; and wherein the carbon-free polymer backbone is linear, cyclic, branched, or a combination thereof.-

Abstract: 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.
