“…The phosphaphenanthrene‐containing flame retardants mainly refer to 9,10‐dihydro‐9‐oxa‐10‐phosphaphenanthrene‐10‐oxide (DOPO) and its derivatives 18–20 . The existence of P‐H bond makes DOPO be able to react with epoxy, quinone, ketone, aldehyde, carbon–carbon double bond, Schiff base, nitrile, and amino groups without catalysis 21–23 . Therefore, through above reactivity of P‐H bond, DOPO was often used to construct flame‐retardant co‐curing agent for epoxy thermoset 24–26 .…”

A novel high phosphorus‐efficiency phosphaphenanthrene curing agent (VND) was synthesized successfully using bio‐based vanillin, N‐phenyl‐p‐phenylenediamine, and 9,10‐dihydro‐9‐oxa‐10 phosphaphenanthrene‐10‐oxide (DOPO). Then, as co‐curing agent, VND combined with 4, 4′‐diaminodiphenyl methane (DDM) to fabricate flame retardant epoxy thermosets (VND/EP/DDM). The VND/EP/DDM thermosets exhibited excellent flame‐retardant performance and toughness, simultaneously. With only 0.35 wt% phosphorus loading, 6%VND/EP/DDM achieved a LOI value of 39.2%, and passed UL94 V‐0 rating. The three reactive functional groups in VND made itself better interpose in the burning process of thermoset matrix, endowing VND with higher efficiency in facilitating matrix carbonization. Meanwhile, the decomposition volatile tracking disclosed the inhibition effect of VND on oxidative cracking. Through gas‐ and condensed‐phased actions, VND decreased the heat release and smoke production of burning epoxy thermosets, efficiently. In addition, three reactive functional groups in VND also brought itself good toughening effect on thermoset matrix, endowing epoxy thermoset with better anti‐impact performance. The flame retarding and toughening behavior of VND provides a new insight to development advanced flame‐retardant epoxy thermosets.

“…Several research groups have reported that a small amount of the conducting polymer, as fillers, is dispersed in PU matrices. Then, it allows for the fabrication of conductive nanocomposites applicable for electronic devices such as sensors [ 59 , 60 ], actuators [ 61 ], membranes [ 62 , 63 ], coatings [ 14 ], and others [ 15 , 16 , 17 , 18 , 19 ].…”

“…They have outstanding properties, including excellent elasticity, elongation, high impact, tensile strength, high abrasion resistance, good weathering resistance, excellent gloss, color retention, and corrosion resistance properties [ 2 ]. The aforementioned properties allow them to find applications in a variety of industries, including leather [ 3 ], foams [ 4 , 5 , 6 ], furniture, fibers [ 7 , 8 , 9 ], elastomers [ 10 ], adhesives [ 11 ], paints [ 12 , 13 ], coatings [ 14 ], sensors [ 7 ], electronic components [ 15 ], biomedical [ 16 , 17 ], and others [ 18 , 19 ]. In spite of versatile applications, the use of standalone PU often cannot ensure that sufficient thermal and mechanical performances are attained.…”

The purpose of this review article is to outline the extended applications of polyurethane (PU)-based nanocomposites incorporated with conductive polymeric particles as well as to condense an outline on the chemistry and fabrication of polyurethanes (PUs). Additionally, we discuss related research trends of PU-based conducting materials for EMI shielding, sensors, coating, films, and foams, in particular those from the past 10 years. PU is generally an electrical insulator and behaves as a dielectric material. The electrical conductivity of PU is imparted by the addition of metal nanoparticles, and increases with the enhancing aspect ratio and ordering in structure, as happens in the case of conducting polymer fibrils or reduced graphene oxide (rGO). Nanocomposites with good electrical conductivity exhibit noticeable changes based on the remarkable electric properties of nanomaterials such as graphene, RGO, and multi-walled carbon nanotubes (MWCNTs). Recently, conducting polymers, including PANI, PPY, PTh, and their derivatives, have been popularly engaged as incorporated fillers into PU substrates. This review also discusses additional challenges and future-oriented perspectives combined with here-and-now practicableness.

“…Even though many conventional flame retardants exhibit excellent flame resistance, halogen-containing flame retardants are banned due to serious environmental problems. Phosphorus-and nitrogen-containing flame retardants as the second category of optional flame retardants still have some environmental problems, such as eutrophication of water caused by the discharge of phosphorus-containing wastewater into the natural world [11][12][13][14][15][16][17][18][19][20][21]. Therefore, there is an urgent need for an environmentally friendly, efficient, and convenient flame retardant.…”

In this study, a kind of inorganic composite flame retardant (Sep@Fe2O3) was prepared by combining solution deposition and calcination methods using sepiolite microfiber material as carrier. This inorganic compound flame retardant was combined with waterborne polyurethane (WPU) through layer-by-layer method to prepare WPU composites. The SEM and EDS, TEM, and XRD were used to characterize the microscopic morphology and crystal structure of WPU composites. Thermogravimetric analysis tests confirmed the good thermal stability of WPU/Sep@Fe2O3 composites; at the temperature of 600°C, the carbon residual percentage of WPU/Sep, WPU/Fe2O3, and WPU/Sep@Fe2O3 composites is 7.3%, 12.2%, and 13.4%, respectively, higher than that of WPU (1.4%). Vertical combustion tests proved better flame-retardant property of WPU/Sep@Fe2O3 composite-coated cotton than noncoated cotton. The microcalorimeter test proved that the PHRR of WPU/Sep@Fe2O3 composites decreased by 61% compared with that of WPU. In addition, after combining with Sep@Fe2O3, the breaking strength of WPU increased by 35%.
