The present teachings relate to various embodiments of a curable ink composition, which once printed and cured form high glass transition temperature polymeric films on a substrate such as, but not limited by, an OLED device substrate. Various embodiments of the curable ink compositions comprise di(meth)acrylate monomers, as well as multifunctional crosslinking agents.

Compositions and techniques for forming organic thin films

The present teachings relate to various embodiments of a curable ink composition, which once printed and cured form polymeric films on a substrate such as, but not limited by, an OLED device substrate. Various embodiments of the curable ink compositions comprise di(meth)acrylate monomers, as well as multifunctional crosslinking agents and curing kinetics control additives.

Methods for increasing the degree of curing and/or reducing the volatile photoinitiator concentration in cured polymeric film, and particularly in cured polymeric films in a multilayered thin film encapsulation stack are provided. Also provided are highly crosslinked and/or low-outgassing thin polymeric films and encapsulation stacks made using the methods.

Two-step process for forming cured polymeric films for electronic device encapsulation

A tool for depositing multilayer coatings onto a substrate. The tool includes a housing defining a vacuum chamber connected to a vacuum source, deposition stations each configured to deposit a layer of multilayer coating on the substrate, a curing station, and a contamination reduction device. At least one of the deposition stations is configured to deposit an inorganic layer, while at least one other deposition station is configured to deposit an organic layer. In one tool configuration, the substrate may travel back and forth through the tool as many times as needed to achieve the desired number of layers of multilayer coating. In another, the tool may include numerous housings adjacently spaced such that the substrate may make a single unidirectional pass. The contamination reduction device may be configured as one or more migration control chambers about at least one of the deposition stations, and further includes cooling devices, such as chillers, to reduce the presence of vaporous layer precursors. The tool is particularly well-suited to depositing multilayer coatings onto flexible substrates, as well as to encapsulating environmentally-sensitive devices placed on the flexible substrate.

A gas and moisture permeation barrier stack deposited by both sputtering and atomic layer deposition techniques. In one embodiment, the barrier stack comprises a bottom barrier layer deposited on a substrate by sputtering and a top barrier layer deposited on the sputtered layer by atomic layer deposition. In one embodiment, the sputtered barrier layer has a water vapor transmission rate of about 10gm/m&#xb7;day or lower, and the top barrier layer improves the water vapor transmission rate of the resulting two-layer barrier stack to about 10gm/m&#xb7;day or lower.

A barrier film composite includes a heat-shrinkable layer having a conformable surface conforming to a surface shape of an object in contact with the heat-shrinkable layer, and a flat surface disposed opposite to the conformable surface; and a barrier layer having a smaller thickness than the heat-shrinkable layer and disposed flat on the flat surface of the heat-shrinkable layer.

An encapsulated device achieves good water vapor transmission rates while reducing the amount of time needed in an inert environment, and thereby reducing the size of the deposition tool used to encapsulate the device. The encapsulated device includes a first barrier layer deposited directly on the device, and a first adhesive and first laminate on the first barrier layer. The laminate comprises a polymeric substrate and a second barrier layer on the substrate. The first barrier layer has a water vapor transmission rate suitable to allow lamination of the laminate on the first barrier layer in a non-inert environment. A method of making an encapsulated device comprises depositing a first barrier layer on the device in an inert environment, applying an adhesive on the first barrier layer in a non-inert environment, and applying a first laminate on the first adhesive in the non-inert environment.

A patterned multilayered barrier film for protecting devices from permeation of moisture and gases includes a substrate, a first layer on the substrate acting as a barrier layer, a second layer on the first layer and acting as a decoupling or planarization layer, and a third layer on the second layer, and acting as a barrier layer. Each of the first and third layers has an area greater than an area of the second layer such that the second layer is completely enclosed between the first and third layers defining an edge perimeter surrounding the second layer that is completely sealed between the first and third layers. The patterned multilayered barrier film may be cut into individual barrier units between portions of the second layer such that portions of the second layer of each individual barrier unit are completely edge-sealed between the first and third layers.

Methods of making an integrated barrier stack and optical enhancement layer for protecting and improving the light out coupling of encapsulated white OLEDs are described. The method includes optimizing the thickness of various layers including one or more of the plasma protective layer, the initial organic layer, the initial inorganic barrier layer, and the inorganic barrier layer and polymeric decoupling layer for the barrier stack. The thickness is optimized for at least one of total efficiency, or intentional color point shift so that the encapsulated OLED has enhanced light outcoupling compared to the bare OLED.

The method includes optimizing the thickness of various layers including the initial inorganic barrier layer and the inorganic barrier layer and polymeric decoupling layer for the barrier stack.

An implantable catheter is provided that may be disinfected without removal from the body of a patient, using a photocatalytic method to activate a reaction on the catheter surface that generates oxidizing agents in the form of Reactive Oxygen Species ('ROS') and thus destroy microorganisms in a biofilm that is present or forming. A catheter system includes the implantable catheter, a light source, and a source of power operably connected to the light source. Methods are also provided for disinfecting the implantable catheter in vivo.

In one embodiment, the present disclosure relates generally to a method for thermally decomposing a complex precursor salt. In one embodiment, the method includes heating a salt in a reactor until a molten salt is formed, adding the complex precursor salt to the molten salt in the reactor and removing a volatile precursor halide formed from thermal decomposition of the complex precursor salt from the reactor.
