Abstract

The invention belongs to the technical field of functional materials, and particularly relates to a multi-response shape memory polyurethane material which comprises the components in percentage by mass: 6.0-10.0% of thermoplastic polyurethane, 0.5-1.0% of acrylic crosslinking resin, 0.1-1.0% of a nano reinforcing material, 0.2-1.0% of a nano conductive material, 0.1-0.6% of an organic antibacterial material, and the balance being a solvent based on 100% of total mass of the multi-response shape memory polyurethane. Through the modification and enhancement effects of the components on the polyurethane material, the polyurethane material not only has an excellent shape memory function and response performance to stimulation of water, pH and electricity, but also has good conductivity and antibacterial performance, so that the stimulation response range of the shape memory polyurethane material is expanded, the shape memory polyurethane material has a multi-response shape memory function, meets the application requirements of a multifunctional flexible sensor, and widens the application range of the shape memory polyurethane material.

Description

technical field

[0001] The invention belongs to the technical field of functional materials, and in particular relates to a multiple-response shape-memory polyurethane material and a preparation method thereof, a flexible sensor and a conductive textile. Background technique

[0002] With the continuous progress and development of society and science and technology, people's requirements for materials are getting higher and higher, and various new functional materials are applied. Shape memory polymer smart materials with self-diagnosis, self-adaptation, shape recovery and other characteristics are convenient. It is one of the important ones and has broad application prospects. Shape memory polymer (SMP) refers to a polymer with an initial shape that can be restored to its original shape by external stimulation after being deformed and fixed under certain external conditions. It has the advantages of light weight, low price, easy processing, large deformation and Corrosion ...
