Embodiment Construction

[0026] The following describes in detail the embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary, and are intended to explain the present invention and should not be construed as limiting the present invention.

[0027] The present invention is achieved based on the following findings of the inventors:

[0028] In recent years, polymer-based composite materials with self-healing function are difficult to meet the requirements of material life, durability, anti-intrusion and other properties and capabilities in various fields of engineering, so they cannot be widely used. The inventors have found through in-depth research that this is because most of the above polymers are formed on the basis of polymer materials with reversible chemical bonds. For example, using hydrogen bonds, reversible covalent bonds (such as Diels-Alder reaction), ion...

Abstract

The invention provides a magnetically-induced heating self-repairing thermoplastic nanocomposite material, and particularly provides a thermoplastic polymer product with the self-repairing function. The thermoplastic polymer product comprises a body and gamma-Fe2O3 nano-particles. The body is formed by a thermoplastic polymer. The gamma-Fe2O3 nano-particles are dispersed into the body. Accordingly, the gamma-Fe2O3 nano-particles induce the thermoplastic polymer body to complete the self-repairing function, the good chemical and mechanical performances are provided for the polymer product through the thermoplastic polymer body, and then the performance of the polymer product with the self-repairing function can be improved, so that the using effect of the polymer product is improved.

Description

technical field [0001] The present invention relates to the field of materials, in particular, to a magnetically induced self-healing thermoplastic nanocomposite material, and more particularly, to a thermoplastic polymer product with a self-healing function and a method for making the thermoplastic polymer product self-healing . Background technique [0002] Engineering materials are prone to fatigue aging and accidental damage due to long-term load resistance and external intrusion under complex working conditions. The aging and damage process of most materials mostly starts with the appearance of local defects, and rapidly develops into serious aging damage with the defect area as the weak point. Therefore, reducing and suppressing the internal defects of engineering materials and repairing the micro-defect areas of the materials have become an important means to improve the anti-intrusion performance and service life of the materials. [0003] Therefore, materials with...
