Preparation method for material for high-sensitively intelligent regulating humidity

Abstract

The invention discloses a preparation method for a material for high-sensitively intelligent regulating humidity. The method comprises the following steps: 1) compounding ethyl hydride oxindole; 2) compounding nitrogen hydroxyethyl clopyrane; 3) compounding acroloyl spiropyrane monomer; 4) compounding spiropyrane-based copolymer; and 5) preparing the material in the manner of electrostatic spinning. An intelligent humidity-regulating material prepared according to the preparation method for the material for high-sensitively intelligent regulating humidity disclosed by the invention can automatically store moisture in air under the condition of ultraviolet light or darkness, can automatically release water into air under the condition of visible light or at daytime and is ultrahigh in sensitivity, so that the function of intelligently regulating humidity can be achieved.

Description

technical field [0001] The invention relates to the field of humidity control materials, in particular to a preparation method of a highly sensitive and intelligent humidity control material. Background technique [0002] Due to global warming and its inland location and latitude, the climate in the central and western regions of the Inner Mongolia Autonomous Region is getting drier, and the desert distribution accounts for about 37.8% of the total desert area in the country, tending to expand and develop. The dry climate can not only cause many discomforts in human body functions, such as dry mouth, decreased immunity of the respiratory system, nosebleeds, astringent eyes, etc.; it will also cause serious damage to the ecological environment of the local area and surrounding cities. influences. Therefore, it is more and more important to research and develop a new method and new material for effectively regulating air humidity. [0003] Scholars at home and abroad have ca...

Problems solved by technology

At present, there have been a large number of scientific research results on humidity-regulating materials, but most of them focus on the hygroscopicity of materials as the main function, lack of effective methods for moisture release, and for intelligent materials that use external stimuli to control the moisture absorption-release performance The development of

In addition, most of the methods and technologies for preparing hygroscopic materials have shortcomings such as numerous steps, complicated preparation techniques, and unfavorable large-area preparation, which make it difficult to meet practical applications.
