Abstract

The invention discloses a stimuli-responsive polymer grafted wrinkled intelligent surface, and a preparation method and an application thereof, and relates to the technical field of intelligent surfaces. The preparation method comprises the following step: grafting a stimuli-responsive polymer onto the surface of a sample with a wrinkle structure, wherein the sample with the wrinkle structure is obtained by heating and thermally shrinking a thermal shrinkage sheet with the surface deposited with a metal film; and the stimuli-responsive polymer has a functional group capable of being grafted with the metal film. According to the invention, the stimuli-responsive polymer can be conveniently grafted onto the surface of the sample with the wrinkle structure, so the preparation method is simple. The wrinkled intelligent surface obtained by using the preparation method provided by the invention has switchable wettability, and can realize directional transmission of acid-base droplets. The stimuli-responsive polymer grafted wrinkled intelligent surface provided by the invention can be extensively applied to the fields of micro-fluidic control, biological medicines, separation engineeringand the like, and has wide application prospect.

Description

technical field

[0001] The invention relates to the technical field of smart surfaces, in particular to a stimuli-responsive polymer grafted wrinkled smart surface and its preparation method and application. Background technique

[0002] Smart surfaces refer to a class of surfaces that behave "intelligently" in response to external stimuli. Its appearance caters to people's needs for intelligent materials, arouses widespread interest in academia and industry, and is one of the hotspots in functional materials research at this stage. The stimuli of the external environment mainly include physical stimuli (such as heat, light, electricity, magnetism, force, etc.), chemical stimuli (such as pH, redox agents, gases, etc.) and biochemical stimuli (such as antigens, enzyme proteins, and glucose, etc.). The response behavior triggered by external stimuli usually manifests as drastic changes in the macroscopic properties of the surface, including wettability, permeability, adhesion...
