Direct specific research areas have been focused on smart damping adhesive (SDA) applications as gaskets, o-rings seals, caulks and conformal coatings [10]. One of the important concepts in creating a practical smart adhesive solution is the concept of layering films, sprays or laminate surfaces to build-up a composite solution as a smart adhesive. **Figure 12** shows an SDA pad that can thermally warm

### **3.1 Smart adhesives summary**

Smart Adhesives have the potential to grow into a significant industry segment of Adhesives, Coatings, bonding agents, layers and hybrid chemistry solutions that do not yet exist today. In the future it is possible that we will achieve layered adhesive solutions that can sense, monitor, communicate, and potentially self-heal. There are many uses of thermal, electrical and physical displacement that will become features in adhesives that will extend the life and functionality of the mating objects as well as the adhesive itself.

The advancements in microencapsulation, film layering, polymer research and hybrid material matrix design is moving exponentially and will likely be a part of your future.
