Disclosed is a method for mechanically anchoring polymers on the surface of a porous substrate by trapping polymer chains within the pores of the substrate under capillary forces. Surface modification of the porous substrate is achieved by anchoring one end of the polymer chains within the pores while one or more other ends of the polymer chains dangle from the surface of the porous substrate. The method provides a unique way of modifying the surface of a material without chemical reactions or precursor-substrate interactions.

This application provides a plate, a method for manufacturing same, and an electronic device. The method includes: forming a resin layer on a surface of a matrix, where the matrix is formed from organic matter, and a material forming the resin layer is different from a material forming the matrix; immersing the matrix in a first solution, the first solution containing a dye; and lifting the matrix formed with the resin layer out of the solution, where a height by which the matrix is lifted out of the solution per minute is not greater than 180 mm.

A method for transferring a graphene film is provided. The method includes spin-coating a cera alba containing solution onto a surface of the graphene film on a metal substrate to form a cera alba layer as a supporting layer, so as to obtain a first stack having the cera alba layer, the graphene film and the metal substrate in sequence; removing the metal substrate with an etching solution to obtain a second stack having the cera alba layer and the graphene film, transferring the second stack onto a target substrate to obtain a third stack having the second stack and the target substrate, and drying the third stack; removing the cera alba layer with an organic solvent. By using natural non-toxic harmless cera alba as a supporting material, it is possible to obtain the graphene film with a clean and intact surface and low sheet resistance.

Provided are a composition, a film, and a film forming method. The composition includes: silica particles; a silicone-based surfactant; and a solvent, in which a content of the silicone-based surfactant in the composition is 0.01 to 0.30 mass % or a content of the silicone-based surfactant is 0.05 to 5.00 mass % with respect to a total solid content of the composition.

Methods are provided for selectively depositing a material on a first surface of a substrate relative to a second, different surface of the substrate. The selectively deposited material can be, for example, a metal, metal oxide, or dielectric material.

A free radical curable automotive body primer is provided that has a color change corresponding to the progress of the cure process until a dry to sand condition has been attained and an internal colored guide coat that does not change color given its exposure to ambient air and as a result, has a different color on the surface of the primer than when in bulk, allowing for the detection and removal of low spots or other imperfections from a vehicle body by additional sanding of the inventive primer to remove oxidized guide coat colorant surface regions. The cure color change is achieved through resort to at least one color changing dye that reacts with a free radical cure initiator during the vehicle body priming process and changes color to indicate when the primer composition has achieved a level of cure so as to be dry enough to sand.

One variation of a method for fabricating a dermal heatsink includes: fabricating a substrate defining an interior surface, an exterior surface opposite the interior surface, and an open network of pores extending between the interior surface and the exterior surface; activating surfaces of the substrate and walls of the open network of pores; applying a coating over the substrate to form a heatsink, the coating comprising a porous, hydrophilic material and defining a void network; removing an excess of the coating from the substrate to clear blockages within the open network of pores by the coating; hydrating the heatsink during a curing period; heating the heatsink during the curing period to increase porosity of the coating applied over surfaces of the substrate; and rinsing the heatsink with an acid to decarbonate the coating along walls of the open network of pores in the substrate.

Fluorescent rare earth glass frits are suitable for laser marking. A marking composition including fluorescent glass frits is disclosed that is capable of emitting fluorescence under irradiation of ultraviolet rays. A method of forming marks or indicia on a substrate using the fluorescent rare earth glass frits is also disclosed.
