Abstract

The invention discloses a polymer-based composite material sensing civil engineering structure super-deformation, and a preparation method and an application thereof. The polymer-based composite material is prepared from the raw materials of polyacrylamide, montmorillonite, water, methyl cellulose, polyvinyl pyrrolidone and a carbon-based material. With the adhesiveness of polyacrylamide after absorbing water, montmorillonite is added in polyacrylamide, such that a polymer-based material with adjustable flexibility and large deformation is prepared; and the carbon-based material is doped in the polymer substrate, such that the composite material with good conductivity is prepared. According to the strain-sensing composite material provided by the invention, polymer is adopted as a substrate, and the material is flexible, such that the material can sense the super-deformation of a civil engineering structure. The raw materials needed in the preparation are easy to obtain. The preparation method and needed instrument are easy to realize.

Description

technical field

[0001] The invention relates to a deformation-sensing polymer-based composite material and its preparation method and application, in particular to a polymer-based composite material capable of sensing super-large deformation of civil engineering structures, its preparation method and application. Background technique

[0002] Civil engineering structures involve all aspects of human life, and the monitoring of structures is of great significance. Civil engineering structures refer to various engineering facilities built on the ground or underground, on land or in water, directly or indirectly serving human life, production, military affairs, and scientific research, such as houses, roads, dams, bridges, power stations, airports, and protective engineering . In recent years, a large number of buildings, bridges and other public facilities have caused irreversible major life and economic losses due to structural damage. If the structure can be well monitored,...
