Article treated with silica particles and method for treating a surface of the article
View Patent ↗An article including a substrate, and a base layer formed on a surface of the substrate, and methods for treating the surface of the substrate are provided.
1. An article comprising:
a substrate;
a base layer formed on a surface of the substrate, wherein the base layer has a thickness less than 1 μm, and the base layer is heat-treated on the substrate at a temperature of about 200° C. to about 900° C.; and
a coating layer formed on a surface of the base layer,
wherein the base layer comprises silica particles, wherein an average size of the silica particles is about 20 nm to about 1 μm.
2. The article of claim 1 , wherein the base layer improves an adhesive property of the surface of the substrate.
3. The article of claim 1 , wherein the silica particles comprise porous particles.
4. The article of claim 1 , wherein the base layer comprises silica particles with uniform sizes.
5. The article of claim 1 , wherein about 95% or more of the total silica particles comprise sizes of about 40% to about 160% of a average particle size.
6. The article of claim 1 , wherein the base layer comprises silica particles with different sizes.
7. The article of claim 1 , wherein the less than about 95% of the total particles comprise sizes of about 40% to about 160% of a average particle size.
8. The article of claim 1 , wherein the base layer comprises one or more layers comprising silica particles.
9. The article of claim 1 , wherein the substrate comprises material selected from the group consisting of metals, glass, ceramics, vinyl, masonry, concrete, natural stones, artificial stones and plastics.
10. The article of claim 1 , wherein the coating layer comprises paint.
11. The article of claim 1 , wherein the base layer has a thickness of about 20 nm to about 500 nm.
12. The article of claim 1 , wherein the substrate comprises a ceramic.
13. The article of claim 1 , wherein the substrate is a silicon wafer.
14. The article of claim 1 , wherein the substrate comprises a metal.
15. The article of claim 1 , wherein the substrate comprises plasma-treated plastic.
16. The article of claim 1 , wherein the substrate includes an irregular shape.
17. The article of claim 1 , wherein the base layer is heat-treated on the substrate at a temperature of about 200° C. to about 400° C.
18. An article with improved adhesion characteristics comprising:
a base layer comprising silica particles, wherein an average size of the silica particles is about 20 nm to about 1 μm;
a substrate contacting one side of the base layer, wherein the substrate comprises a metal or a ceramic; and
a coating layer contacting a side of the base layer opposite the substrate, wherein the coating layer comprises paint, wherein the base layer is heat-treated with the substrate at a temperature of about 200° C. to about 900° C.
19. The article of claim 1 , wherein heat-treating the base layer on the substrate provides improved adhesion characteristics.
20. An article with improved adhesion characteristics comprising:
a base layer consisting essentially of silica particles, wherein an average size of the silica particles is about 20 nm to about 1 μm;
a substrate contacting one side of the base layer; and
a coating layer contacting a side of the base layer opposite the substrate, wherein the coating layer comprises paint.
