Flammability and thermal analysis of thermoplastic polyurethane/DOPO
DOPO derivatives are considered as a suitable alternative to halogenated flame-retardants due to their flame extinguishing behavior in the gas phase and condensed phase [ 26 ]. Recently, the synergistic interaction between nanoparticle and DOPO derivatives is discussed [ 27 ].

A Furan-based Phosphaphenanthrene-containing Derivative as a Highly
In order to reduce greenhouse gas emissions, developing flame retardants from bio-based resources has aroused extensive interest in recent years. In this work, we utilized furfural (biomass) and 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) to synthesize a bio-based co-curing agent (FGD) to combine with 4,4’-diaminodiphenyl methane (DDM) for obtaining a low-phosphorus loading
Fire-retardant high-performance epoxy-based materials
This class of compounds can be mainly categorized into silicones, silica, organosilanes, silsesquioxanes, and silicates, functioning in FR systems as additives or other forms [52,90]. ... The...
Recent Developments in Organophosphorus Flame Retardants
Recently, aromatic DOPO based phosphinate flame retardants have been developed with relatively higher thermal stabilities (>250 °C). Such compounds have potential as flame retardants for high...
- Are Dopo derivatives flame retardants?
- Despite a growing interest in DOPO derivatives as flame retardants there exist no comprehensive review, which summarizes in detail their synthesis and application in epoxy systems since 2011 (last decade) [, , , , , ].
- What is a non-reactive Dopo based flame retardant?
- Non-reactive DOPO-based flame retardants have been widely used in aviation where a relatively lower loading is required to achieve improved fire behavior and allow a good compromise between flame retardancy and mechanical performances in epoxy systems , , , .
- What are reactive Dopo based flame retardants for epoxy resins?
- This review focuses on recent advances in reactive DOPO–based flame retardants for epoxy resins, including reactive monomers, curing agents and hybrid structures. There are also highlighted fire retardant mechanisms of the DOPO derivatives and thermal and mechanical features of the epoxy systems.
- What are non-reactive Dopo derivatives?
- Non-reactive DOPO derivatives allow effective hybrid flame retardant mechanism and, in some hybrid –DOPO derivatives, good mechanical performances for the resin can be realized. This review focuses primarily on the technological advances in the last ten years (2011 onwards) on non-reactive DOPO derivatives for epoxy systems.
- Does a Dopo derivative improve flame resistance?
- In this study, a DOPO derivative containing phosphorus and nitrogen in the molecular structure with amino as terminal group (DOPO-NH 2) was incorporated into PLA to improve the flame resistance. The addition of this DOPO derivative on the thermal stability, flame retardancy and mechanical properties of PLA was investigated.
- How does Dopo exhibit a flame retardant mechanism?
- DOPO exhibits mainly gas phase flame retardant mechanism through the release of free radical scavangers generated during material combustion. It may also exhibit condensed phase by dehydration to form carbonaceous protective layers .
