A hard coating composition comprises a dopamine, a plurality of inorganic oxide particles, and a solvent. The dopamine reduces the film forming time of an anti-fogging coating. A hard coating film using the hard coating composition, and a coated article using the hard coating film are also provided.
摘要:
An abradable coating for application to a gas turbine engine part is formed from a titanium aluminide alloy, a filler material, and porosity. The coating may be applied to a part such as a casing made from a titanium alloy.
摘要:
The invention provides a taper composite metal-matrix composite, inclusive of a taper composite metal which forms a plurality of taper metal nanorods on a flake metal substrate and a photocurable polymer such as photocurable epoxy or photocurable PMMA. A taper composite metal-matrix composite is prepared from a blend comprising taper composite metal and a photocurable polymer to produce electromagnetic wave shielding and adsorbing effect, and diminish the target infrared thermal radiation.

A titanium black dispersion includes titanium black particles, a dispersant, and an organic solvent. When the titanium black dispersion is for a wafer level lens, 90% or more of dispersed objects that consist of the titanium black particles have particle diameters of 30 nm or less, or dispersed objects including the titanium black particles contains Si atoms and the content ratio of Si atoms to Ti atoms (Si/Ti) in the dispersed objects is 0.05 or higher. When the titanium black dispersion is used for formation of a light-shielding film that is provided on one side of a silicon substrate having an image pickup device section on the other side, and that shields against infrared light, 90% or more of dispersed objects that consist of the titanium black particles have particle diameters of 30 nm or less.
摘要:
A composite structure includes at least one resin matrix layer having a resin material and a plurality of fiber elements and a plurality of titanium particles provided in the resin material. A method of toughening a resin matrix layer is also disclosed.
摘要:
A hybrid film-forming composition is prepared by forming an aqueous mixture including an organofunctional silane, a metal chloride, and an acid, and boiling the mixture. A base is added to the aqueous mixture to substantially neutralize the mixture and to form a hydroxide of the metal. A colloidal suspension including the metal hydroxide and a siloxy compound is formed. A peroxide-based solution is added to the suspension to form a suspension including a peroxide of the metal. The suspension is allowed to equilibrate at room temperature. The suspension is boiled at a pressure greater than atmospheric pressure to form a hybrid film-forming composition including the condensation product of a siloxy compound and a metal peroxide. A coating formed from the hybrid film-forming composition may be hydrophobic or hydrophilic.
摘要:
A polyester with a carbon black content of up to 20% by weight, based on the polyester, is condensed, after transesterification of DMT with diol, or after esterification of terephthalic acid with diol, with the aid of a titanium-based catalyst. The carbon black is added in the form of a carbon black dispersion together with the polycondensation catalyst to the transesterification product or esterification product. The carbon black dispersion comprises gas black or furnace black and a dispersing agent, and these are dispersed in diol. The diameter of the carbon black particles is below that of carbon black particles in a polyester using an antimony compound as catalyst.
