Inspired by Nature
In nature, damage to an organism elicits an automatic healing response. Here at AMI, we apply this same concept to synthetic material design. The result is a new class of SMART materials — self-healing polymeric systems that are capable of autonomically repairing themselves after damage.
The Only Truly Self-healing System
AMI’s self-healing technology repairs damage to coatings when it occurs, which extends lifetime and performance. Our systems offer maximum protection, responding to damage without the need for detection by manual intervention.
Our self-healing microcapsule systems can be incorporated into a coating as the coating itself is created. Only when the surface of this coating is compromised will the nearby microcapsules be activated, releasing their self-healing agents into the damaged area. When the healing agents mix, a polymerization reaction occurs that heals the damaged area.
- Microencapsulated healing agents
- Compatible with most coating systems
- Robust microcapsules engineered to activate only when coating is damaged
- Microcapsules customizable to specific applications
- An expandable technology platform
The Science of Self-Healing
A truly self-healing material is capable of repairing itself in its intrinsic environment — and it does this without any external intervention as soon as the damage occurs. AMI is developing this self-healing technology for use in materials that are not easily accessible for maintenance.
Regardless of the source, damage to a material ultimately results in mechanical failure. This renders the material incapable of performing in its intended application. AMI’s self-healing materials are designed to repair damage that begins at the micron scale, effectively stopping the propagation of the damage and extending the lifetime of the material.
When mechanical damage occurs in one of our self-healing materials, the microcapsules are ruptured, causing healing agents to be released to the site of the damage. These agents mix and polymerize, which heals the damage and restores structural continuity. The microcapsules are designed to be robust enough to survive the manufacturing process and the deployment of the material in its intended application.
The advantage of the microencapsulation approach to developing self-healing materials is versatility. A range of self-healing chemistries can be microencapsulated to maximize compatibility with matrix materials. On top of this, the size of the microcapsules and the thickness of their shell walls can be customized for various coating thicknesses and chemical environments. Additional functionality specific to our customers’ applications and markets can be added to the self-healing material to provide a truly unique and customized solution.
