摘要： This invention provides monomer formulations suitable for making preceramic polymers, which can be converted into ceramic matrix composites and other ceramic structures. The monomer formulations is used for 3D printing and comprise (a) a monomer molecule containing (i) non-carbon atoms and (ii) two or more functional groups selected from the group consisting of aliphatic ether, cyclic ether, vinyl ether, epoxide, cycloaliphatic epoxide, oxetane, and combinations, analogues, or derivatives thereof; (b) a cationic photoinitiator or photoacid generator; and (c) a 3D-printing resolution agent selected from the group consisting of UV absorbers, fluorescent molecules, optical brighteners, and combinations thereof.

摘要： This disclosure provides coatings that eliminate the problem of persistent oil or grease smudges deposited on transparent coatings. Some variations provide an oil-smudge-resistant material comprising discrete inclusions dispersed within a continuous matrix, wherein one of the discrete inclusions and the continuous matrix is an oleophobic material, and the other is an oleophilic material. Specific embodiments incorporate segmented polyurethanes with oleophobic fluoropolymers and oleophilic hydrocarbons. Some embodiments utilize inorganic oleophilic particles in an oleophobic matrix. Some embodiments condense urethane-silane crosslinkers with other silanes to form discrete domains of oleophobic or oleophilic silanes within a continuous matrix of oleophilic or oleophobic polymer. Waterborne coatings are provided in which one of the discrete inclusions and the continuous matrix is derived from an aqueous dispersion of a linear crosslinkable polyurethane containing charged groups, and the other is derived from a crosslinking agent containing charged groups.

摘要： 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.
