  • Surface modification method based on polymerization and cross-linking solidification of dopamine and/or derivatives thereof
    Patent number: 10633554
    Abstract: The present invention provides a surface modification method based on the polymerization and cross-linking solidification of dopamine and/or its derivatives, which belongs to the technical field about composite material fabrication. The principle of dopamine polymerization and the formation process of polydopamine coating layer are the foundation of the present invention. This innovative method is established after deeply analyzing the failure mechanism of polydopamine coating layer in severe environments, such as organic solvents and acidic/alkalic environments. The critical work is finding out an eligible cross-linking agent which could react with the active functional groups in polydopamine. After cross-linking reaction, the soluble low-molecular-weight dopamine oligomers could be transformed into the insoluble three-dimensional stereographic networks.
