Abstract

The invention discloses a preparation method of poly(phenol-amine) superhydrophilic particulates. The preparation method of the poly(phenol-amine) superhydrophilic particulates comprises the following steps: firstly adding a micro-nano material into a solution of polyphenol and polyamine, reacting for a period of time, and separating, so that the superhydrophilic particulates are obtained. The preparation method of the poly(phenol-amine) superhydrophilic particulates is simple in process, easy to operate, controllable in technology, mild in conditions, good in repeatability, low in cost and convenient for popularization and application, the obtained poly(phenol-amine) superhydrophilic particulates have good superhydrophilic performance, can be applied to various materials and have a broad application range.

Description

technical field [0001] The invention relates to the field of surface modification of materials and compounding of organic and inorganic materials, in particular to a method for preparing superhydrophilic materials by using polyphenolamines to modify micro-nano materials. Background technique [0002] Wettability is one of the important properties of a solid surface, and the contact angle (CA) is usually used to characterize the wettability of a liquid to a solid. The wettability of solid surfaces is very important for basic research and practical applications. In recent years, superhydrophilic and superhydrophobic surfaces have attracted extensive attention as a very special phenomenon. Super-hydrophilic surface refers to the surface with a contact angle of less than 5° with water. It has important characteristics such as self-cleaning, anti-fog, and improved surface heat exchange efficiency. It can be widely used in many fields such as scientific research, production, and l...
