cracked-mobile-screens Concordia researchers from the OH Research Group in the Faculty of Arts and Science are looking at ways to “self-heal” cellphones, and their research could have broader implications as well.

Excellent Results at Room Temperature


The team created self-healing polymer networks through very simple synthetic routes. The developed materials demonstrated excellent results at room temperature.

These materials can quickly repair damages and cracks due to the self-healing mechanism,” says Pothana Gandhi Nellepalli, Horizon postdoctoral fellow.

One of the major difficulties in these types of projects is to maintain a balance between the mechanical and self-healing properties,” explains PhD candidate Twinkal Patel. This research stands out from similar work on the topic because of its focus on temperature.

Our goal is to not compromise the toughness of the network while adding dynamic ability to self-heal damage and scratches. We focus on achieving complete healing of scratches at just room temperature. This feature sets our research apart from others.”

As a result, these materials save consumer’s time and money while also extending the lifespan of the material used and reducing environmental burden.”

Future Use of Technology


This technology allows a device to store energy and convert it into electricity when repeated movement is applied — think of LED lights that are activated when you pass by.

“In the future, I would like to use self-healing polymer networks for improving the battery life of triboelectric nanogenerators,” Patel adds.

This same technology could definitely be used to extend the lifespan of cellphone batteries. In the future, we would be able to charge them just by walking.”
