The utilization of carbon nitride to reinforce the mechanical and thermal properties of UV-curable waterborne polyurethane acrylate coatings

Vinyl hydroxyl silicone oil (VHSO) and carbon nitride (C3N4) were use to modify and reinforce the UV-curable waterborne polyurethane acrylate, respectively. The results showed that all the composite films have good hardness, water resistance, mechanical properties and thermal stability, it is promising for a number of applications, e.g., for metal and wood for their surface protection.
