Embodiment 1

[0023] Preparation of nano-gold particles: All glass containers were rinsed with aqua regia, and then washed with distilled water for several times; 12.5ml of protective agent hexadecyltrimethylammonium bromide (0.004g / ml) was diluted and added to 5g of chloroauric acid (1wt% aqueous solution) diluted to 100ml mixed solution, mixed evenly with a glass rod and transferred to a three-necked flask, heated to boiling, quickly injected 15ml of sodium borohydride (0.00113g / ml), waited for 10 minutes, stopped heating and continued stirring Fill the bottle after a few minutes; cool to room temperature and store in the dark at 4°C. Mix and stir nano-gold particles and graphene oxide at a mass ratio of 1:10 to prepare nano-gold / graphene oxide composite material, and mix nano-gold / graphene oxide composite material with 0.1wt% of polyurethane material into polyurethane material to obtain nano-gold / graphene oxide self-healing materials such as figure 1 shown. Materials after surface da...

Abstract

The invention discloses a preparation method for a nano gold / graphene oxide self-repairing material. A nano gold / graphene oxide composite material can be prepared by mixing and stirring nano-gold particles and graphene oxide at a ratio of 1 : 5-10; and a nano gold / graphene oxide self-repairing material can be prepared by mixing the nano gold / graphene oxide composite material accounting for 0.05-0.5 wt% of a thermoplastic resin material into the thermoplastic resin material. A repairing method for the nano gold / graphene oxide self-repairing material is also disclosed. The repairing method includes irradiating the nano gold / graphene oxide self-repairing material with a laser. The material and repairing method have characteristics of low energy consumption during repairing and low cost, and are simple and economic in repairing means and easy to realize industrialization.

Description

technical field [0001] The invention relates to a preparation and repair method of a self-repair material, in particular to a preparation and repair method of a nano-gold / graphene oxide self-repair material. Background technique [0002] Thermoplastic resin materials are widely used in various industries, and it has become an indispensable element in industrial production, especially in the fields of automobile and electronics manufacturing. However, after a long period of use, thermoplastic resin materials will produce micro-cracks of different scales due to weathering and wear, and these cracks will continue to expand and gather, and eventually become cracks. Once the thermoplastic resin material is destroyed, its various properties will be significantly affected. [0003] Self-healing materials based on microcapsules exhibit a strong ability to repair damage. However, this technique also has some limitations. First, embedding microcapsules in resin materials will reduc...
