Shape memory effects in self-healing polymers

Shape Memory Assisted Self-Healing Coating

In this communication, we report the preparation and characterization of new shape memory assisted selfhealing (SMASH) coatings. The coatings feature a phaseseparated morphology with electrospun thermoplastic poly(εcaprolactone) (PCL) fibers randomly distributed in a shape memory epoxy matrix. Mechanical damage to the coating can be self-healed via heating, which simultaneously triggers two eve...

Self-healing Polymers

These images present the dramatic reduction in corrosion of a steel plate coated with a self-healing coating (right) as compared to a conventional coating. Both samples were scratched and placed in 5% NaCl for 5 days. The background is an optical image (2x magnifi cation), in the foreground is an SEM image of the scratch. In the self-healing sample, the scratch has almost completely self-healed...

Self-healing Polymers

Self-healing polymers are a new class of smart materials that have the capability to repair themselves when they are damaged without the need for detection or repair by manual intervention of any kind. Increasing demand for petroleum feed stocks used to produce polymer and the need for polymeric materials with improved performance in challenging applications continue to drive the need for mater...

Shape-memory polymers.

Material scientists predict a prominent role in the future for self-repairing and intelligent materials. Throughout the last few years, this concept has found growing interest as a result of the rise of a new class of polymers. These so-called shape-memory polymers by far surpass well-known metallic shape-memory alloys in their shape-memory properties. As a consequence of the relatively easy ma...
