Polarized raman analysis of polymer chain orientation in ultrafine individual nanofibers with variable low crystallinity
(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 ...
Electrospinning of highly crystalline polymers for strongly oriented fibers
(American Chemical Society, 2020-09-23)
Electrospun nanofibers (NFs) often demonstrate an exponential increase in mechanical and other properties at reduced diameters. Molecular orientation emerges as a key parameter for the performance of amorphous and low ...
Quantifying polymer chain orientation in strong and tough nanofibers with low crystallinity : towards next generation nanostructured superfibers
(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 ...
