제목 A novel flame retardant DOPO-derivatives in a chitosan aerogel: a synergistic effect of containing nitrogen, phosphorus and silicon.
초록 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) is one of the widely used flame retardant materials due to its own environmentally friendly property. This halogen-free DOPO additives can not only prevent emitting the hazardous substances, but also increase the thermal stability. DOPO-vinyltrimethoxysilane (DOPO-VTS) was synthesized and added to the chitosan aerogel in attempt to improving the flame retardancy of the polymer aerogel. The DOPO-VTS was characterized by 1H, 31P NMR (nuclear magnetic resonance) and FT-IR (Fourier-transform infrared spectroscopy). This synthesized DOPO-VTS chitosan aerogel was investigated by SEM (scanning electron microscope), TGA (thermal gravimetric analysis), and BET (Brunauer-Emmett-Teller) to differentiate the pure chitosan aerogel and DOPO-VTS chitosan aerogel. Besides, the flame retardant properties can be proved to microcalorimeters and flammability tests and the outcomes verify the improved flame retardancy of DOPO-VTS chitosan aerogel.
