Dr. Kenneth Pestka II and recent Longwood physics graduate Jonathan Buckley (16) publish paper in Scientific Reports.

The paper titled, “Elastic evolution of a self-healing ionomer observed via acoustic and ultrasonic resonant spectroscopy,” by Dr. Kenneth Pestka II and Longwood physics graduate Jonathan Buckley (16) along with collaborators Stephen Kalista Jr. and Nicholas Bowers was published today in Nature Publishing Group’s open access journal Scientific Reports.

The manuscript presents a relatively new approach, time dependent resonant spectroscopy, and solves an outstanding problem of healing timescales in a self-healing poly (ethylene co-methacrylic acid) ionomer. The article also presents a new experimental discovery of persistent time dependent spectral evolution in this unusual material. The results are likely to lead to an increased interest in the experimental approach, with application to other polymeric and ionomeric materials. The results also provide details needed to improved theoretical models of these and other related self-healing materials.
