چکیده
|
In this study, fluorescent polyurethane was synthesized by using 5,7-dihydroxy-4-methylcoumarin as the chain extender. the chemical structure of the resulting polyurethane was confirmed by fourier-transform infrared spectroscopy. tensile analysis was used to measure the young’s modulus and strain at break of the fluorescent polyurethane, and the fluorescence emission was observed under uv light.
