A water/oil repellent treatment agent which includes a specific polymer-modified silane having a fluorooxyalkylene structure on the main chain and a hydrolyzable group at the end of the molecular chain, and/or a partial (co)hydrolyzate/condensate thereof, has a percent weight loss following one hour of exposure at 250° C. of 10% or less. The treatment forms a layer having excellent water and oil repellency, scuff resistance and mold release properties even when heated to 250° C. or more.

A coating composition and a method for coating metallic substrates, such as aircraft components exposed to elevated temperatures and/or oxidative conditions. The coating composition includes an aqueous mixture having about 2 vol % to about 50 vol % organosilane, about 0.3 to about 25 vol % metal alkoxide, and about 0.1 to about 30 vol % organic complexing agent. The coating composition may be deposited on a metallic substrate and cured to form a sol-gel coating on the surface of the substrate that is adherent to the substrate, and oxidation and discoloration resistant.

A flexible display device including a hard coating layer, the hard coating layer containing first hard coating oligomers, second hard coating oligomers having greater molecular weights than the first hard coating oligomers, a cross-linker, and a photoinitiator. The first hard coating oligomers may maintain the hardness of the hard coating layer and the second hard coating oligomers may improve the flexibility of the hard coating layer, such that damage to the hard coating layer may be prevented or reduced even when the flexible display device is bent.

A pattern-forming method includes forming on one face side of a substrate, a directed self-assembling film, and removing a part of the directed self-assembling film. The directed self-assembling film is formed from a composition including a block copolymer and a solvent. The block copolymer includes a first block composed of a first repeating unit that includes a silicon atom, a second block composed of a second repeating unit that does not include a silicon atom, and a first group that bonds to at least one end of a main chain and links to the first block. The first group is a monovalent group that forms a compound having ClogP of no less than 2.4 provided that a methyl group is bonded to an atom on a side of the main chain. The first group does not comprise a hetero atom.
