NOVELTY - Fluorocarbon polymers is widely used in industry due to their weather resistance, corrosion resistance, self-cleaning, and anti-sticky properties. However, such as polytetrafluoroethylene (PTFE), a problem of too soft and heat resistance at high temperature need to improve. This patent improve a anti-scratch and corrosion resistant non-stick coating structure is characterized the properties of scratch resistance, high temperature resistance, corrosion resistance, non-sticking, etc. The structure reacts the fluorocarbonated graphene with the nanometer silicon dioxide colloid into a composite material, and the composite material coating on the surface of a substrate, and then re-forming the composite into a hardened layer of the composite by a heating process or catalytic action, applying process control to make the surface layer of fluorocarbonized graphene different due to the difference of surface energy and cohesion Innumerable uniform small bumps, which have a non-stick hydrophobic function due to the lotus effect. The middle layer has graphene and silicon dioxide particles to form a high hardness of the composite material with homogeneous large bumps. Under middle layer, a bottom layer of polycrystalline silicon dioxide bond with substrate to form a high-adhesive layer to present a high-quality coating layer.
