Polarized raman analysis of polymer chain orientation in ultrafine individual nanofibers with variable low crystallinity
Papkov, Dimitry; Pellerin, Christian; Dzenis, Yuris A. (American Chemical Society, 2018-10-26)Recent mechanical studies of ultrafine electrospun polymer nanofibers showed they can simultaneously possess high strength and toughness attributed to high degree of chain alignment coupled with low crystallinity. Quantitative analysis of macromolecular ... -
Quantifying polymer chain orientation in strong and tough nanofibers with low crystallinity : towards next generation nanostructured superfibers
Papkov, Dimitry; Delpouve, Nicolas; Delbreilh, Laurent; Araujo, Steven; Stockdale, Taylor; Mamedov, Sergey; Maleckis, Kaspars; Zou, Yan; Andalib, Mohammad Nahid; Dargent, Eric; Vinayak, Dravid; Holt, Martin V.; Pellerin, Christian; Dzenis, Yuris A. (American Chemical Society, 2019-04-19)Advanced fibers revolutionized structural materials in the second half of the 20th century. However, all high-strength fibers developed to date are brittle. Recently, pioneering simultaneous ultrahigh strength and toughness were discovered in fine (<250 ...
