Embodiment Construction

[0026] Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the figures 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 realized based on the following discoveries of the inventors:

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

Abstract

Provided is a thermoplastic polymer product having self-healing functionality. The thermoplastic polymer product comprises: a main body comprising a thermoplastic polymer; and γ-Fe2O3 nano particles configured to scatter in the main body.

Description

technical field [0001] The present invention relates to the field of materials, in particular, to a magnetically induced self-repairing thermoplastic nanocomposite material, more specifically, to a thermoplastic polymer product with self-repair function and a method for making the thermoplastic polymer product self-repair . Background technique [0002] Engineering materials are prone to fatigue aging and accidental damage due to long-term resistance to load and external intrusion under complex working conditions. However, the aging and damage process of most materials 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 materials has become an important means to improve the anti-intrusion performance and service life of materials. [0003] Therefore, materials with self-heal...
