Abstract: With the increasing awareness of environmental protection, the development and application of novel halogen-free flame retardants have attracted a lot of attention recently. 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) and its derivatives are regarded as one of the most promising and widely used halogen-free flame retardants among various phosphorus-containing compounds due to its superior reactivity, thermal stability and oxidation resistance. Accordingly, DOPO-containing compounds have been incorporated with versatile polymeric matrices and exhibited advanced flame retardancy performances in gaseous phase and condensed phase.
Keywords: 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide, flame retardant, polymeric materials, application.
