Abstract

The invention discloses a preparation method of a polydopamine concentric ring structure color film, and relates to the technical field of polydopamine structure color films. According to the preparation method of the polydopamine concentric ring structure color film, a fabric serves as a substrate, a dopamine-trihydroxymethyl aminomethane solution serves as a buffer reagent, and under an aerobicand alkalescent condition, dopamine is self-polymerized into PDA particles; when the PDA particles are assembled to form the structure color film, due to oscillation, the PDA particles are assembled along oscillation ripples, therefore, the color film with different colors and concentric ring appearance is formed on the surface of the fabric, and the colorful property of the structure color film is improved; meanwhile, during dopamine polymerization, a certain concentration of a P(GMA-co-PEGMA) adhesive solution is added, so that the structure color film and fabric fibers are cross-linked, andthe color fastness of the structure color film is improved.

Description

technical field [0001] The invention relates to the technical field of polydopamine structural color, in particular to a method for preparing a polydopamine concentric ring structural color film. Background technique [0002] The textile industry has experienced more than one hundred years of rapid development, and its products have played an important role in all aspects of our lives. At present, the coloring of textiles is basically achieved through printing and dyeing. However, the impact of printing and dyeing wastewater on the environment limits the development of the textile industry. With the improvement of environmental protection requirements in various countries and the enhancement of people's environmental protection awareness, the textile printing and dyeing industry urgently needs to develop a green and pollution-free coloring method. [0003] Different from dyeing, structural color is the color produced by objects through physical effects such as scattering, ...
