Infrastructure that Heals Itself

Self-healing materials have the ability to repair damages on their own due to their mechanical friction and with the efflux of time. Post injury, the molecules of these materials re-adjust to replicate the original material. Initiation of cracks and other types of damages on the microscopic level change the electrical, thermal, and acoustical properties of material, leading to its complete failure. These materials correct these damages with or without human intervention.

The global self-healing materials market is expected to reach $4.1 billion by 2025. Rising demand for high-quality construction materials is due to increase infrastructure projects and urbanization is projected to steer the market growth in the near future.

Concrete segment dominated the market, with revenue exceeding $25 million this past year. Now, looking ahead the market will pick up even more during the forecast period. Reversible polymers accounted for 36% of global consumption in 2016. Self-healing materials minimize the maintenance cost required for repairing damages, which is expected to be a critical factor for market growth.

These specialty products also extend the life span of the material, as well as the base layer or product on which they are applied. Microencapsulated or nano-encapsulated healing agents are present in capsulated constituents, which are released upon rupture. The growth of the market is expected to escalate due to unique properties of the products, yielding long-term financial benefits as compared to conventional composites.

Increased purchasing power and rise in demand for advanced construction materials in Canada and Mexico have increased preference for the use of self-healing composites. The growth of this market will help infrastructure improvements and cut down on repairs.
