Abstract
The invention relates to the field of superhydrophobic materials, particularly to a polyfunctional purine-based compound and a preparation method thereof, and applications of the polyfunctional purine-based compound in preparation of superhydrophobic materials. According to the present invention, the polyfunctional purine-based compound modifies substrate materials so as to substantially improve the adhesion of superhydrophobic materials during application; the polyfunctional purine-based compound has the purine group so as to improve the durability of superhydrophobic materials; by using theproperties and the preparation method of the supramolecule, nanometer oxide materials can be modified with the compound to obtain superhydrophobic materials so as to improve the adhesion and the durability of superhydrophobic materials; and the compound further has a variety of other groups, such that the application range of the superhydrophobic material modified with the compound is wide.
Description
technical field [0001] The invention relates to the field of superhydrophobic materials, in particular to a multifunctional purine compound, its preparation method and its application in the preparation of superhydrophobic materials. Background technique [0002] Superhydrophobic means that the contact angle between the surface of the material and water is >150°. This material has good hydrophobicity and can realize various functions such as anti-fouling, self-cleaning, and waterproof. One of the hotspots of the application. Through the research on the super-hydrophobic parts of plants and animals with super-hydrophobic ability, such as lotus leaves, butterflies, geckos, etc., two important conditions for the surface with super-hydrophobic properties are gradually summarized: first, the surface must have roughness. Micro-nano structure; Second, the surface must be modified with low surface energy substances. [0003] As far as artificially synthesized superhydrophobic m...
