Researchers make self-healing polymers for cracked cell phone screens

When you occur to’re adore most cell phone customers, at one level you would perchance per chance well even bear experienced a cracked disguise disguise.

This pesky anxiety will even be anxious to are living with, and it’s expensive to repair.

Two Concordia researchers from the Oh Research Neighborhood in the College of Arts and Science are taking a seek at ways to “self-heal” your cell phone, and their review could well also bear broader implications as smartly.

Turning down the warmth

“Among the predominant difficulties in all these tasks is to purchase a balance between the mechanical and self-healing properties,” explains Ph.D. candidate Twinkal Patel (BSc 17), first creator on the paper “Self-Healable Reprocessable Triboelectric Nanogenerators Fabricated with Vitrimeric Poly(hindered Urea) Networks,” printed in ACS Nano.

Patel says this review stands out from an analogous work on the topic resulting from its focal level on temperature.

“Our purpose is to no longer compromise the toughness of the network while adding dynamic ability to self-heal hurt and scratches. We focal level on achieving full healing of scratches at precise room temperature. This characteristic sets our review other than others.”

Saving time and money

The crew created self-healing polymer networks thru very simple synthetic routes. The developed supplies demonstrated pleasing outcomes at room temperature.

“These supplies can mercurial restore damages and cracks on account of the self-healing mechanism,” says Pothana Gandhi Nellepalli, Horizon postdoctoral fellow and co-creator on the paper.

“This ability that, these supplies assign patrons time and money while also extending the lifespan of the topic topic feeble and reducing environmental burden.”

Lifestyles in the Oh lab

Patel is rapid to credit the mission’s success to the Oh Research Neighborhood, led by John Oh, professor and Canada Research Chair (Tier II) in Nanobioscience in the Department of Chemistry and Biochemistry.

“Working right here has been a immense journey. At some level of my time right here I in actuality bear met fabulous and supportive individuals who bear made this lab in actuality feel adore a second family,” she says.

“I’m very thankful for the mentorship I purchased from my supervisor to publish my first paper. I in actuality feel performed to seek the laborious work I’ve performed be printed.”

What else can this technology enact?

“In due direction, I would adore to exhaust self-healing polymer networks for bettering the battery lifetime of triboelectric nanogenerators,” Patel provides.

This technology permits a application to store energy and convert it into electricity when repeated inch is utilized—mediate LED lights which are activated at the same time as you occur to circulation by.

“This same technology could well also positively be feeble to extend the lifespan of cell phone batteries. In due direction, we would be ready to charge them precise by walking.”
