Resendes Rui,

A double coating, curing method, cured coating, and kit are provided. A first layer of the double coating can be a first cure coating composition, which has a first hydroxy-functional resin, a first crosslinking agent, and a non-polar catalyst. A second layer of a second cure coating composition can have a second hydroxy-functional resin, a second crosslinking agent, and a polar catalyst. The non-polar catalyst catalyzes crosslinking between the second hydroxy-functional resin and crosslinking agent, and not between the first hydroxy-functional resin and crosslinking agent. The polar catalyst catalyzes crosslinking between the first hydroxy-functional resin and crosslinking agent, and not between the second hydroxy-functional resin and crosslinking agent. The polarity of the catalysts can facilitate catalyst migration from one layer to the other. The separate compositions can be shelf-stable and/or the curing can occur at low temperature.

The present application provides switchable, homogeneous paint composition and methods of painting and/or forming films or coatings using the composition. The composition includes a liquid having an aqueous solution and dissolved acid gas (e.g., carbonated water), and a switchable polymer. The switchable polymer converts from a protonated, water-soluble form in the liquid to a water-insoluble unprotonated form following removal or substantial removal of the liquid and acid gas.

Switchable water-based paint or coating compositions

A double coating, curing method, cured coating, and kit are provided. A first layer of the double coating can be a first cure coating composition, which has a first hydroxy-functional resin, a first crosslinking agent, and a first catalyst. A second layer of a second cure coating composition can have a low hydrophilicity acrylic resin as a second hydroxy-functional resin, a second crosslinking agent, and a second catalyst. The first catalyst catalyzes crosslinking between the second hydroxy-functional resin and crosslinking agent, and not between the first hydroxy-functional resin and crosslinking agent. The second catalyst catalyzes crosslinking between the first hydroxy-functional resin and crosslinking agent, and not between the second hydroxy-functional resin and crosslinking agent. The first and/or second hydroxy functional resins can facilitate catalyst migration from one layer to the other. The separate compositions can be shelf-stable and/or the curing can occur at low temperature.

Methods and systems for use of switchable water, which is capable of reversibly switching between an initial ionic strength and an increased ionic strength, is described. The disclosed methods and systems can be used, for example, in distillation-free removal of water from solvents, solutes, or solutions, desalination, clay settling, viscosity switching, etc. Switching from lower to higher ionic strength is readily achieved using low energy methods such as bubbling with C0, CSor COS or treatment with Bronsted acids. Switching from higher to lower ionic strength is readily achieved using low energy methods such as bubbling with air, inert gas, heating, agitating, introducing a vacuum or partial vacuum, or any combination or thereof.

Systems and methods for use of water with switchable ionic strength

The present application provides a composite material that comprises a solid and solid-supported non-polymeric switchable moiety, wherein the switchable moiety comprises a functional group that is switchable between a first form and a second form, said first form being neutral and hydrophobic, and said second form being ionized and hydrophilic. The composite material converts to, or is maintained in, said second form when the switchable moiety is exposed to COat amounts sufficient to maintain the ionized form. The composite material converts to, or is maintained in, said first form when COis removed or reduced to an amount insufficient to maintain the ionized form. COis removed or reduced by exposing the composite material to heat and/or a flushing inert gas such as N, Ar, or air. Envisioned uses of these composite materials includes removing water from non-aqueous solvents, removing water vapor from gaseous mixtures, and cleaning industrial reaction vessels and/or pipelines.

Switchable materials, methods and uses thereof

Shelf-stable low temperature cure coating compositions that include a hydroxy-functional resin, a crosslinking agent, and a catalyst that does not catalyze the crosslinking reaction between hydroxy-functional resin and the crosslinking agent contained therein, but instead between a hydroxy-functional resin and a crosslinking agent contained in a different low temperature cure coating composition. In addition, low temperature cure composite coatings that include: a waterborne basecoat containing a first hydroxy-functional resin, a first crosslinking agent, a first catalyst, and an organic solvent; and a solventborne topcoat containing a second hydroxy-functional resin, a second crosslinking agent, a second catalyst, and water, where the first catalyst migrates into the topcoat from the basecoat and catalyzes the reaction between the second hydroxy-functional resin and crosslinking agent, and the second catalyst migrates into the basecoat from the topcoat and catalyzes the reaction between the first hydroxy-functional resin and crosslinking agent.

The present application provides a polymer composite comprising at least one polymer and a reclaimed pyrolyzed carbon black (pCB), wherein the pCB comprises less than about 10 &#x3bc;g/g of polycyclic aromatic hydrocarbons (PAH). Also provided are polymer composite and consumer-ready formulations of the low PAH pCB and methods of manufacturing such composites and formulations.

Ionomers comprising ionic groups such as, for example, tetraalkylammonium groups and methods of making such ionomers. For example, the ionomers can be produced by ring opening metathesis polymerization of alkene-containing monomers with tetraalkylammonium groups and, optionally, alkene-containing monomers without tetraalkylammonium groups. The ionomers can be used in applications such as, for example, fuel cell applications.

Ionomers and methods of making same and uses thereof

The present application provides precursor compounds useful for deposition of a groupmetal on a substrate, for example, a microelectronic device substrate, as well as methods of synthesizing such precursor compounds. The precursor compounds provided are mono-metallic compounds comprising a diaminocarbene (DAC) having the general formula: 'DAC-M-X', where the diaminocarbene is an optionally substituted, saturated N-heterocyclic diaminocarbene (sNHC) or an optionally substituted acyclic diaminocarbene, M is a groupmetal, such as copper, silver or gold; and X is an anionic ligand. Also provided are methods of synthesizing the precursor compounds, metal deposition methods utilizing such precursor compounds, and to composite materials, such as, e.g., microelectronic device structures, and products formed by use of such precursors and deposition methods.
