Abstract

Self-healing materials have attracted much attention because that they possess the ability to increase the lifetime of materials and reduce the total cost of systems during the process of long-term use; incorporation of functional material enlarges their applications. Graphene, as a promising additive, has received great attention due to its large specific surface area, ultrahigh conductivity, strong antioxidant characteristics, thermal stability, high thermal conductivity, and good mechanical properties. In this brief review, graphene-containing polymer composites with self-healing properties are summarized including their preparations, self-healing conditions, properties, and applications. In addition, future perspectives of graphene/polymer composites are briefly discussed.

Highlights

  • Regenerative abilities allow creatures to repair damaged functions to prolong their life span.Researchers are inspired to design and prepare self-healing materials to increase the lifetime of materials and reduce the total cost of systems during the process of long-term use

  • Graphene oxide was incorporated as corrosion inhibitor and the self-healing ability was attributed to the PEI/PAA multilayers

  • The microwaves absorbed by reduced functionalized graphene oxide (GO) turned into heat and promoted the healing process of the composites based on DA chemistry

Summary

Introduction

Regenerative abilities allow creatures to repair damaged functions to prolong their life span. Polymers 2018, 10, 114 of 25 graphene/polymer composites will endow them with the ability of repairing themselves after damage and enlarge their service life. A lot of studies have been reported on the self-healing of the will endow them with the ability ofto repairing themselves after(Figure damage enlargeittheir service life. TheTherefore, polymericit is matrix and to can be used in the field of mechanics, composites, which combine outstanding properties of graphene with advantages of the polymeric thermology, photology and the electricity. Matrix be used the field of mechanics, thermology, photology and electricity In and this can review, the in current advances in self-healing graphene/polymer composites have been. The current in self-healing composites have been summarized, including their advances preparation methods, graphene/polymer self-healing conditions, properties and summarized, including their preparation methods, conditions, properties and applications.
