The structure and the mechanical properties of a newly developed highmodulus/high strength cellulose fibre spun from an anisotropic solution in phosphoric acid are discussed and compared with those of existing regenerated cellulose fibres. The crystal structure of the fibre is of the cellulose II modification, and the highly oriented and crystalline fibres have an initial filament modulus of 44GPa,...
Charge-transfer fluorescence probes show a strong response of the intensity and wavelength positions of their spectra to solvent polarity and mobility. Such properties have been applied in the past to follow polymerization kinetics and solvent-induced effects (e.g., swelling) in polymeric materials. An important advantage of charge-transfer fluorescence probes is that they can be measured at extremely...
