Synthesis of a novel DOPO-based polyphosphoramide with high
A novel and highly effective flame retardant (FR), DOPO-TMPM oligomer, was synthesized by a simple condensation of 4-(hydroxymethyl)-2,6,7-trioxa-1-phosphabicyclo[2.2.2]octane 1-oxide...
DOPO-Decorated Two-Dimensional MXene Nanosheets for Flame
The results revealed that PLA/Ti 3 C 2 –DOPO (3 wt %) displayed a V-0 rating in the UL-94 test. The enhancement against fire hazard was reflected by the significant reduction in the peak heat release rate (33.7%), total heat release (47%), peak CO production (58.8%), and total smoke production (41.7%).
Polymers | Free Full-Text | Synthesis of DOPO-Based
9,10-dihydro-9-oxa-10-phosphorus-10-oxide (DOPO) and its derives are one of the most outstanding commercial phosphorus-containing flame retardants used in polymers, due to their high thermal stability, strong chemical durability, and minimal side effects on the mechanical properties of polymer matrix [ 20 ].
An efficient and durable DOPO/H3PO4-based flame retardant
In this study, a novel high-efficiency and durable flame retardant DOPO–ammonium phosphate (DOPO–AP) was synthesized and applied for cotton fabric by a facile process. Nuclear magnetic resonance (NMR 1H, 13C, 31P) spectroscopy confirmed the molecular structure of DOPO–AP. Flame retardancy of the treated cotton was studied by limiting oxygen index (LOI), vertical combustion, scanning
Synthesis of a novel flame retardant based on DOPO
An intumescent flame retardant (DOPO-DAM) containing phosphorus and nitrogen was synthesized viaa two-step process and then, it was incorporated into waterborne polyurethane to serve as a reactive flame retardant for preparing flame-retarded WPU (FR-WPU).
