DLC (Diamond Like Carbon) coated plastic as well as preparation method and application thereof

The invention relates to the technical field of high polymer materials, and discloses DLC (Diamond Like Carbon) coated plastic as well as a preparation method and application thereof. Comprising a plastic base material and a DLC film coated on the surface of the plastic base material. According to the DLC coated plastic, the hardness of the plastic base material can be remarkably enhanced after the plastic base material is coated with the DLC, the plastic can achieve the performance of a metal material, meanwhile, the abrasion resistance of the DLC is high, the durability of the DLC coated plastic can be remarkably improved, the service life of the DLC coated plastic is prolonged, and meanwhile the application range of the DLC coated plastic is widened; uvioresistant polyformaldehyde resin is adopted as a raw material to prepare a plastic base material, then the plastic base material is subjected to surface modification through ultraviolet irradiation, so that the surface of the plastic base material can reac
