Zusammenfassung: | The invention discloses a preparation method and application of multifunctional novel nanoparticles with natural sources. Nano-particles extracted from natural plants are chemically modified to obtain bifunctional particles with antibacterial property and lubricating property. The particles, a photoinitiator and a hydrophilic polymer monomer form a mixed solution, the surface of a high polymer material is coated with the mixed solution, and in-situ polymerization of the monomer is carried out under ultraviolet irradiation to form a gel coating. In the monomer polymerization process, the nanoparticles can enhance the mechanical property of the gel network, and endow the coating with excellent antibacterial property. Meanwhile, the hydrophilicity of the composite gel is further improved due to the high hydration capability of the nanoparticles, and the lubricating property of the coating is enhanced.
