Abstract: This invention provides multifunctional coatings containing multiple components that usually do not associate with one another, from deposition of waterborne precursor compositions. Some variations provide a multiphase waterborne composition comprising a first-material phase containing a first material and a second-material phase containing a second material chemically different than, but covalently bonded to, the first material, wherein the first material and/or the second material contains ionic species. The first-material phase and the second-material phase are microphase-separated on an average length scale of phase inhomogeneity from 0.1 to 100 microns. The first and second materials may be selected from hydrophobic materials, hydrophilic materials, hygroscopic materials, oleophobic materials, and/or oleophilic materials, for example. Due to the first-material phase and the second-material phase being microphase-separated, the multiphase waterborne composition possesses a simultaneous combination of properties, rather than a combined average. Precursors and methods are also disclosed.

Abstract: Some variations provide an anisotropic thermally conductive polymer composition comprising a plurality of polarizable, thermotropic main-chain liquid-crystal polymer molecules with crystalline domains. The liquid-crystal polymer molecules are in a nematic phase or a smectic phase, and at least 80% of the crystalline domains are aligned along a crystal axis. A method of making an anisotropic thermally conductive polymer composition comprises: synthesizing or obtaining a polymer containing polarizable domains; heating the polymer to form a polymer melt; cooling the polymer melt to form a thermotropic liquid-crystal polymer; exposing the thermotropic liquid-crystal polymer to an electrical field, thereby aligning the polarizable domains along a crystal axis; and recovering the thermotropic liquid-crystal polymer as an anisotropic thermally conductive polymer composition. The polymer composition may be formed into an object characterized by thermal conductivity along the minimum dimension that is at least three times greater than thermal conductivity along the maximum dimension.

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/thermosetswitchable.

Abstract: Low-friction fluorinated coatings are disclosed herein. A preferred low-friction material contains a low-surface-energy fluoropolymer having a surface energy between about 5 mJ/m 2 to about 50 mJ/m 2 , and a hygroscopic material that is covalently connected to the fluoropolymer in a triblock copolymer, such as PEG-PFPE- PEG. The material forms a lubricating surface layer in the presence of humidity. An exemplary copolymer comprises fluoropolymers with average molecular weight from 500 g/mol to 20,000 g/mol, wherein the fluoropolymers are (α,ω)-hydroxyl-terminated and/or (α,ω)-amine-terminated, and wherein the fluoropolymers are present in the triblock structure T-(CH 2 -CH 2 -O)-CH 2 -CF 2 -O-(CF 2 -CF 2 -O) m (CF 2 -O) n -CF 2 -CH 2 -(O-CH 2 -CH 2 ) p -T where T is a hydroxyl or amine terminal group, p = 1 to 50, m = 1 to 100, and n = 1 to 100.

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.
