Synthesis, Characterization, and Optical Performance of a Novel Fluorescent Waterborne Polyurethane

Abstract: A fluorescent fluorescent waterborne polyurethane (FWPU) was synthesized by conjugating fluorescer, isodium 4,4 -bis[4-anilino-6-hydroxyethylamino-6-(2-choloronilino-1,3,5-triazin-2-yl)amino]stilbene-2,2 -disulphonate (RSW), into polyurethane backbone as a chain extender. The expected structure of FWPU was confirmed by Fourier transform infrared, 1 H nuclear magnetic resonance, and UV−vis spectrophotometer, and the effect of fluorescer content, temperature, as well as quencher on the fluorescence performances … Show more
