Abstract

Belonging to the technical field of chemistry and chemical industry production, the invention discloses a method for rapid preparation of a polymer multilayer film. The method can realize rapid preparation of a polymer multilayer film on a planar substrate and a non-planar substrate, and is suitable for industrial production. The method integrates a hypergravity technology and a layer-by-layer self-assembly technology, or in other words, an alternate layered self assembly process is carried out in a hypergravity machine so as to prepare a polymer multilayer film. The method can effectively enhance the preparation speed of a polymer multilayer film without changing the properties of the prepared polymer multilayer film. Being suitable for substrates of different shapes and different materials, the method has strong concentration adaptability, and can realize rapid preparation of a polymer multilayer film under a low concentration. Being suitable for acidic assembling liquids, alkaline assembling liquids and other assembling liquids of different properties, the method of the invention has the characteristics of simple operation process, short operation time, high efficiency, and suitability for industrial production.

Description

technical field [0001] The invention belongs to the technical field of chemical and chemical production, and mainly relates to a method for quickly preparing polymer multilayer films. The method can realize the rapid preparation of polymer multilayer films on planar and non-planar substrates, and the method is suitable for in industrial production. Background technique [0002] Today, with the increasing development of modern technology, materials with a single function can no longer meet people's needs, and composite materials with various improved properties are more and more popular.
