One micron length scale controls kinetic stability of low energy glasses
Kenneth L. Kearns, M. D. Ediger, Heiko Huth +1
AC nanocalorimetry was used to measure the reversing heat capacity Cp of low energy indomethacin glasses as they isothermally transform into the supercooled liquid. As the film thi…
Comparison of mechanical and molecular measures of mobility during constant strain rate deformation of a PMMA glass
Benjamin Bending, M. D. Ediger
We performed constant strain rate deformation and stress relaxation on a poly(methyl methacrylate) glass at Tg - 19 K, utilizing three strain rates and initiating the stress relaxa…
Highly organized smectic-like packing in vapor-deposited glasses of a liquid crystal
Ankit Gujral, Jaritza Gomez, Jing Jiang +6
Glasses of a model smectic liquid crystal-forming molecule, itraconazole, were prepared by vapor deposition onto substrates with temperatures ranging from Tsubstrate = 0.78 Tg to 1…
Reversing strain deformations probe mechanisms for enhanced segmental mobility of polymer glasses
Kelly Hebert, M. D. Ediger
Optical probe reorientation measurements were performed to monitor changes in segmental dynamics resulting from the nonlinear deformation of a polymer glass. Segmental dynamics wer…
Using Deposition Rate and Substrate Temperature to Manipulate Liquid Crystal-like Order in a Vapor-deposited Hexagonal Columnar Glass
Camille Bishop, Zhenxuan Chen, Michael F. Toney +3
We investigate vapor-deposited glasses of a phenanthroperylene-ester, known to form an equilibrium hexagonal columnar phase, and show that liquid crystal-like order can be manipula…
Multi-step deformation experiment and development of a model for the mechanical behavior of polymeric glasses
Grigori A Medvedev, Enran Xing, Mark D Ediger +1
Traditional models for stress-strain behavior of glassy polymers are based on the assumption that the critical features of the stress-strain response can be explained by changes in…
