Ultraviolet-pH response polymer hydrogel and its use

Abstract

A polymer ultraviolet-pH response p(AA-co-AAAB) copolymer aqueous gel is prepared by synthesizing molecular chain containing azobenzol group intermediate monomer AAAB and preparing p(AA-co-AAAB) copolymer aqueous gel by it. It has stable deformation and excellent ultraviolet response. It can be used for miniature optical devices, optical switches and sensors.

Description

technical field The invention relates to an intelligent polymer material, in particular to a responsive intelligent polymer hydrogel and its application. Background technique Smart materials are a hot spot in the field of new materials research at home and abroad in recent years. The so-called smart material is a material that senses changes in external conditions (sensor function), and through self-judgment and self-conclusion (processor function), consciously self-regulates, modifies and repairs (actuator function). Its main feature is that it can "perceive" different surrounding environments and their changes, and respond accordingly. Therefore, smart materials are usually composed of matrix materials, sensitive components, actuation units, and information processors. Among them, the actuation unit is an extremely important component, and its main function is to respond appropriately by changing its own geometric shape or other properties after sensing environmental st...

AI Technical Summary

Problems solved by technology

The deformation stability and deformation controllability of photodeformable polymer hydrogel materials prepared by this physical method are poor, which limits its application research.

However, there are few reports at home and abroad on the preparation of intelligent photodeformable polymer hydrogel materials by chemical methods, and there are no related reports on photo-pH-induced deformation polymer hydrogel materials.
