    摘要: Aspects involve a stretchable composite film including a polymer material having at least a portion of the polymer material being densified through covalently-attached fluorination molecules. In certain specific examples, fluorinated molecules are covalently attached to a surface region, in the form of a layer or film (e.g., polymer semiconductor (PSC) film of a transistor substrate) to facilitate operational stability and/or to encapsulation performance (e.g., stretchability-related performance). In certain other specific examples, the surface region and a fluorinated layer are used in a cooperative configuration to provide stability in the PSC film in one or more harsh environments characterized by one or more of humid air, and immersion of the PSC film in a bio-based fluid.

    摘要: The present invention provides a photocurable composition containing an ultraviolet absorber, which has high photocurability and yields a cured material having a high cutting capacity against ultraviolet rays from the outside, a low yellow index, and colorlessness and transparency. The present invention relates to a sheet-shaped photocurable composition which includes the following components (A) to (D), and when a cured material obtained after photocuring the photocurable composition has a thickness of 150 μm, a yellow index of the cured material is 4.0 or less and a light transmittance of the cured material at a wavelength of 385 nm is 5.0% or less: a component (A): a (meth)acrylate compound, a component (B): a film forming resin, a component (C): a photoinitiator, and a component (D): an ultraviolet absorber.
