The present disclosure is drawn to printed foam panels for electronic devices. In one example, a printed foam panel for an electronic device can include a substrate, a primer layer on the substrate, a foam pattern on the primer layer, and a clear coating layer on the foam pattern. The foam pattern can cover a first portion of the substrate and leave a second portion uncovered. The foam pattern can include a printed pattern of a foaming composition including a photoacid generator compound and a metal carbonate activated to form the foam pattern.

According to one embodiment, a system for manufacturing a fully impregnated thermoplastic prepreg includes a mechanism for moving a fabric or mat and a drying mechanism that removes residual moisture from at least one surface of the fabric or mat. The system also includes a resin application mechanism that applies a reactive resin to the fabric or mat and a press mechanism that presses the coated fabric or mat to ensure that the resin fully saturates the fabric or mat. The system further includes a curing oven through which the coated fabric or mat is moved to polymerize the resin and thereby form a thermoplastic polymer so that upon exiting the oven, the fabric or mat is fully impregnated with the thermoplastic polymer. During at least a portion of the process, humidity in the vicinity of the coated fabric or mat is maintained at substantially zero.

Films including a water-soluble layer and a vapor-deposited organic coating are disclosed. The films can optionally further include a vapor-deposited inorganic layer. The films exhibit enhanced barrier properties.

A method of preparing a composition for forming a release coating is disclosed. The method comprises preparing a reaction product comprising a polyorganohydrogensiloxane compound having cyclic SiH-functional branching groups interconnected by linear polydiorganosiloxane segments (the “branched cyclic polyorganohydrogensiloxane compound”), by combining together (A) a hydroxyl terminated polydiorganosiloxane and (B) a cyclic polyorganohydrogensiloxane, in the presence of (C) a boron containing Lewis acid and a solvent. A release coating composition including the reaction product comprising the branched cyclic polyorganohydrogensiloxane is also disclosed. The reaction product may be combined with or prepared in the presence of a polyorganohydrogensiloxane diluent and stripped of solvent to prepare the composition as a blend of the branched cyclic polyorganohydrogensiloxane and the polyorganohydrogensiloxane diluent for use in solventless-curable compositions.

The present invention relates to a UV curable water-based polyelectrolyte composition and a method for producing a polyelectrolyte film using the same, which provides a polyelectrolyte composition comprising: at least one polyelectrolyte selected from Formulas 1 to 3; an acrylate-based material; a cross-linker; a photoinitiator; and a solvent.

Methods of curtain coating substrates are disclosed. In some embodiments, the methods include applying two or more liquid layers simultaneously to a substrate, wherein the multiple layers include a bottom liquid layer comprising a shear thinning liquid, and another liquid layer comprising a viscoelastic liquid. In some embodiments, the disclosed methods include formulating a bottom layer liquid comprising a shear thinning liquid, formulating another layer liquid comprising a viscoelastic liquid, pumping the bottom layer liquid and the other layer liquid through coating dies simultaneously and onto a moving substrate such that the bottom layer liquid impinges on the substrate thereby forming a bottom layer, and the other layer liquid forms another liquid layer above the bottom liquid layer. The inclusion of a bottom liquid layer comprising a shear thinning liquid and other layer comprising a viscoelastic liquid provides for enlargement of the curtain coating window.

The present invention discloses an organic polymer film and a manufacturing method thereof. The organic polymer film is mainly manufactured by the following steps. Firstly, the step (A) provides a xylene precursor and a substrate, and the step (B) places the substrate inside of a plasma equipment. After that, the step (C) evacuates the plasma equipment while introducing a carrier gas which carries vapor of the xylene precursor, and the step (D) turns on a pulse power supply system of the plasma equipment, generating a short pulse for plasma ignition. Finally, the step (E) forms the organic polymer film on the substrate. In the aforementioned steps, the frequency of the short pulse plasma is between 1 Hz˜10,000 Hz, and the pulse period of the short pulse plasma is between 1 μs˜60 μs.

A golf ball comprising a subassembly such as a cover and a coating layer disposed entirely about an outer surface of the subassembly; wherein the coating layer has a first color region, a second color region, and a transition color region that is transitionally disposed between the first color region and the second color region. The first color region has a first color appearance; the second color region has a second color appearance that is different than the first color appearance; and the transition color region has a transitional color appearance that is comprised of the first color appearance and the second color appearance. The transitional color region may be disposed circumferentially about the outer surface of the cover.

A method for rendering material surfaces inert is provided. Exemplary surfaces include ceramic, metal or plastic surfaces. The method is accomplished with functionalized perfluorinated compounds for the formation of hyperhydrophobic structures on the surfaces to create inert surfaces. The inert surfaces produced or can be produced in this way have an extremely low surface energy, are resistant to deposits of substances or cells and have a very low coefficient of friction. Practical uses of the inert surfaces are also provided.
