A matte clear anti-fouling anti-corrosion surface coating and uses thereof, and a matte clear anti-fouling anti-corrosion surface layer and a matte clear anti-fouling anti-corrosion metal, wherein the matte clear anti-fouling anti-corrosion surface coating comprises: a fluorine-modified polysilazane and a solvent, wherein the content of the fluorine-modified polysilazane is approximately 5-80% by weight based on the total weight of the matte clear anti-fouling anti-corrosion surface coating. Accordingly, the coating can be applied to a corrosion-prone metal sheet or a corrosion-prone metal plate with a protective priming coat (a coated object). The coating is stain repellent, hydrophobic, anti-graffiti, corrosion resistant, clear, matte clear, resistant to temperature changes, resistant to impact, and tough among other characteristics, and is capable of not changing the original color or gloss of the coated object; the coating can be cured at room temperature for direct uses outdoors, and/or can be heated and cured for uses in factories. Additionally, the coating can also be applied directly on a surface of a metal that is not susceptible to rusting, wherein the coating can be applied directly after the addition of a matting agent, or without the addition of a matting agent and the coating can still be matte clear as described above.

A biocompatible polymer hybrid nanocomposite coating on a surface of a substrate, such as titanium and its alloys. The coating can be achieved by an electrostatic spray coating, preferably using ultra-high molecular weight polyethylene (UHMWPE) as a matrix for the coating. For example, up to 2.95 wt. % carbon nanotubes can be used as reinforcement, as can up to 4.95 wt. % hydroxyapatite. A dispersion of CNTs and HA in the coating is substantially uniform. The tribological performance of such coatings include high hardness, improved scratch resistance, excellent wear resistance, and corrosion resistance compared to pure UHMWPE coatings.
