Further disclosed herein are methods of producing a coating and applying the coating with a device producing a coating composition jet, and substrates coated by the methods.

The present disclosure relates to a composite membrane and a packaging structure. The composite membrane comprises: a carrier layer; and an information layer, wherein the information layer is disposed on one side of the carrier layer along thickness direction of the composite membrane, and the information layer further comprises a light-transmitting layer, a first pattern layer, and a second pattern layer, which are disposed along the thickness direction of the composite membrane, wherein: the first pattern layer is disposed close to the carrier layer; the light-transmitting layer is disposed on one side of the first pattern facing layer away from the carrier layer; the second pattern layer is disposed on one side of the light-transmitting layer facing away from the carrier layer, and the second pattern layer and the first pattern layer present different visual information of one multi-dimensional object.

A method for manufacturing a closed porous composite material includes 1) preparing a mixture that has 30 to 70 parts by weight of water-dispersed resin, 10 to 300 parts by weight of unexpanded thermal expansion microspheres, and 100 to 550 parts by weight of water, and stirring the mixture thoroughly; 2) preparing a carrier; 3) coating the carrier with the mixture acquired in step 1; 4) heating the carrier so that the unexpanded thermal expansion microspheres expand; and 5) repeating steps 3 and 4 multiple times to acquire a closed porous composite material. The closed porous composite material has a large number of closed cavities and polymer walls separating the closed cavities. The closed cavity is 20 μm to 800 μm in size. The ratio of a total volume of the closed cavities to a total volume of the polymer walls is greater than 16.

The disclosure relates to a thermoset omniphobic composition (such as an omniphobic polyurethane or epoxy composition) which includes a thermoset polymer with first, second, and third backbone segments. The first, second, and third backbone segments can correspond to urethane or urea reaction products of polyisocyanate(s), amine-functional omniphobic polymer(s), and polyol(s), respectively, for omniphobic polyurethanes. Similarly, the first, second, and third backbone segments can correspond to urea or beta-hydroxy amine reaction products of polyamine(s), isocyanate-functional omniphobic polymer(s), and polyepoxide(s), respectively, for omniphobic epoxies. The thermoset omniphobic composition has favorable omniphobic properties, for example as characterized by water and/or oil contact and/or sliding angles. The thermoset omniphobic composition further has favorable barrier properties, for example with respect to water vapor and oxygen transmission as well as water absorption. The thermoset omniphobic composition can be used as a coating on any of a variety of substrates to provide omniphobic properties to a surface of the substrate. Such omniphobic coatings can be scratch resistant, ink/paint resistant, and optically clear.

Components of articles that include an optical element that imparts structural color to the component are provided. Methods of making the components including the optical element, and methods of using the components such as to make an article of manufacture are provided.

One or more aspects of the present disclosure are directed to components having an optical element that imparts structural color to the component or article. The present disclosure is also directed to articles of manufacture including the component having an optical element, and methods for making components and articles having an optical element that imparts structural color.

The present disclosure provides fluid barriers as well as systems and methods of forming fluid barriers. The method includes cleaning, via a blast media, a first side of a component and heating the component to a first temperature. Subsequently, the component is cleaned using a solvent. Subsequent to heating at least the component, a primer coating layer is formed on the first side of the component, and a topcoat layer is formed in contact with the primer coating layer. A primer coating material can be heated to a second temperature prior to formation of the primer coating layer. The first temperature can be different than the second temperature.
