Experimental reflectivity spectra showed the largest difference in reflectivity was obtained at r = 0.6 between prepared CuxN film and Cu film around 650-750 nm, which means the film deposited at r = 0.6 is more suitable for using as optical recording materials.

Introduction With the development of the electronic industry, telecommunication and polymer science, polymer materials have been widely used in electronics, telecommunications, aviation, aerospace , civil, military and defense industries.
But most of the polymer materials can not conduct electricity and have low permeability.
Chemical plating alloys of glass fiber have become a kind of new functional materials, structural materials and irreplaceable for the sustainable development of high-tech materials.
Obviously, alloy coatings were soft magnetic materials.
It described that the alloy coatings of the glass fiber were mainly used as absorbing materials.
