The present disclosure provides a method for preparing hollow glass microbeads coated with graphene oxide, which includes: dispersing graphene oxide into deionized water, to form an aqueous graphene oxide solution; placing hollow glass microbeads into the aqueous graphene oxide solution, to achieve a dispersion liquid; and simultaneously performing an ultrasonic vibration treatment and a drying treatment to the dispersion liquid, to achieve the hollow glass microbeads coated with the graphene oxide. Through simultaneously performing the ultrasonic vibration treatment and the drying treatment to the dispersion liquid, the graphene oxide is uniformly coated on the surface of the hollow glass microbeads, and thus the surface properties of the hollow glass microbeads are maintained, because no other additives such as adhesives are required.

To provide a water/oil repellent layer-provided substrate having a water/oil repellent layer excellent in abrasion resistance, a deposition material and a method for producing a water/oil repellent layer-provided substrate.

The water/oil repellent layer-provided substrate of the present invention is a water/oil repellent layer-provided substrate comprising a substrate, an undercoat layer and a water/oil repellent layer in this order, wherein the water/oil repellent layer comprises a condensate of a fluorinated compound having a reactive silyl group, the undercoat layer contains an oxide containing silicon and an alkaline earth metal element, and the ratio of the molar concentration of the alkaline earth metal element in the undercoat layer to the molar concentration of silicon in the undercoat layer is from 0.005 to 5.

A superstrate can include a body having a surface; a buffer layer overlying the surface; and a protective layer overlying the buffer layer, wherein the protective layer has a surface roughness that is equal to or less than a surface roughness of the surface of the body. The protective layer can include a material that can be selectively removed with respect to the buffer layer, and the buffer layer can include a material that can be selectively removed with respect to the body of the superstrate. The superstrate can be used for more planarization or other processing sequences before the body needs to be replaced, as any defects that may form extend into the protective layer or buffer layer and not reach the body. The layers can be removed and replaced by corresponding new layers without significantly adversely affecting the body.
