The self-healing function of reactive gel catalysts in flexible electronic devices

Introduction

With the continuous advancement of technology, flexible electronic devices have gradually become a research hotspot. Flexible electronic devices have the advantages of bendable, stretchable, and lightweight, and are widely used in wearable devices, medical monitoring, smart packaging and other fields. However, flexible electronic devices are susceptible to mechanical damage during use, resulting in reduced performance and even failure. In order to solve this problem, self-healing materials came into being. As a new self-repair material, reactive gel catalysts have great application potential in flexible electronic devices due to their excellent self-repair performance and good mechanical properties.

Overview of reactive gel catalyst

Definition and Characteristics

Reactive gel catalyst is a smart material with self-healing function that can be automatically repaired by chemical reactions after damage. Its main characteristics include:

Self-repair ability: After mechanical damage, it can automatically repair through chemical reactions to restore the original performance.
Good mechanical properties: It has high strength and toughness, and can withstand certain mechanical stresses.
Environmental Adaptation: Able to maintain stable performance under different environmental conditions.

Working Principle

The self-healing function of reactive gel catalysts depends mainly on their internal chemical reactions. When the material is damaged, the catalyst activates internal chemical reactions, creating new chemical bonds, which repairs the damaged site. This process usually includes the following steps:

Dause Detection: After the material is mechanically damaged, the internal catalyst is activated.
Chemical reaction: The catalyst initiates internal chemical reactions and generates new chemical bonds.
Repair completed: New chemical bonds are formed, the damaged part is repaired, and the material restores its original performance.
