Abstract：Silicone rubber has excellent properties such as temperature resistance,corrosion resistance,and radiation resistance,and is widely used in electronics,aerospace,automotive industry and many other fields.In the process of long-term use,silicone rubber will be damaged by various factors,resulting in material properties degradation,seriously affecting the reliability and service life of the material.Intrinsic self-healing silicone rubber can be healed through reversible bonds between molecules.Because of the dy-namic reversibility of the bonds,it can be repeatedly broken and reassembled,so the intrinsic self-healing silicone rubber does not need to add any repair agent and can achieve multiple repairs.This article briefly introduces the research progress of intrinsic self-healing silicone rubber from two aspects:preparation con-ditions and healing conditions.It deeply explores the structural design,repair conditions,repair mecha-nisms,advantages and disadvantages of silicone rubber with different crosslinking networks,and pros-pects its future development.
