Study of the dynamic fragility of polymer nanocomposites: Correlation with damping

Polymer Composites, Volume 44, Issue 9, Page 5619-5632, September 2023., 2023
The dynamic fragility and activation energy were calculated and analyzed on the basis of the dynamic mechanical data of a series of polymer nanocomposites. A general trend of a decreasing dynamic fragility with increasing Tg was found. No monotonic effect of the nanofiller loading on the fragility was detected. Abstract In this work, an extensive study
