“…Reviewing the literatures in the SCI database by June 6, 2022, there are 19 articles related on flame retardant SMPs including thermoplastics and thermosets (Table S1), 5–23 from which three problems are generally found. First, most SMPs get their flame retardancy from phosphorus‐related flame retardants, however, phosphorus‐related flame retardants have been reported to cause eutrophication of the water bodies 24 ; moreover, they also tend to degrade thermal stability of thermally resistant resins 25,26 .…”

Fabricating thermally resistant and strong shape memory bismaleimide resin with intrinsic halogen-free and phosphorus-free flame retardancy is still an interesting issue with significant challenge. Herein, a new bismaleimide (MSi) containing siloxane structure was synthesized, which was copolymerized with 2,2 0 -diallylbisphenol A to develop three new resins coded as MD-x, x represents the molar ratio of allyl to maleimide. The composition-structure-performance relationship and mechanism of MD-x resins are systematically studied. All MD-x resins not only show self-distinguish feature, but also have high glass transition temperatures (127.4-160.1 C), high impact strengths (12.09-18.77 kJ/m 2 ), high flexural strengths (91.3-97.5 MPa) and excellent shape memory properties, their shape fixation rates and shape recovery rates exceed 93% after three shape memory cycles. These attractive and competitive comprehensive performances demonstrate that the problems for halogen-free and phosphorus-free flame retardant shape memory polymers have been successfully solved, this is derived from the unique structure of MD-x resins.

“…A significant drawback is its poor thermal stabilitythis restricts its service temperature by a significant amount as CFs lose their mechanical integrity at temperatures above 120 °C. Present research focuses on the incorporation of inorganic materials into CFs like zinc oxide, 30 magnesium hydroxide, 31 silicate nano clays, 32 titanium dioxide, 33 and so forth to promote the formation of the char layer. Two techniques are employed in this work, viz.…”

The surge in the usage of wireless electronics and communication devices has engendered a different form of pollution, viz. electromagnetic (EM) pollution, and yet another serious issue, EM interference (EMI). There is a legitimate need to develop strategies and materials to combat this issue, otherwise leading to dreadful consequences. Functional textiles have emerged as the modern materials to help attenuate EM waves due to the numerous advantagesflexibility being the most important. In addition to this, there is an inherent advantage of multiple interfaces in coated fabrics that can engender significant attenuation. Herein, we report a coating having multifunctional propertiescapable of blocking both UV and EM radiation (predominantly of the microwave frequencies) with flame-retarding properties. The layer described here comprises iron titanate (FT) synthesized from its sustainable precursorilmenite sand and carbon nanotubes (CNTs) dispersed in waterborne polyurethane. It is worth noting that FT's use as a multifunctional material is being reported for the first time. It was observed that a single layer of coated fabric shows an EMI shielding effectiveness of −40 dB translating to 99.99% attenuation and similarly a UV blocking of 99.99% in the wavelength range from 200 to 400 nm. The microwave shielding properties of the fabric were demonstrated using a Bluetooth module, where the coated fabric was able to block the incoming Bluetooth signals to the module from a mobile phone. Besides, the coated fabrics exhibited phenomenal enhancement in thermal stabilitya 5% increase in the limiting oxygen index was observed upon the application of the coating. Such exceptional properties tend to complement cotton fabrics' existing utility, thereby extending their use to specialty applications.

“…Magnesium hydroxide (MH) is a non‐toxic, halogen‐free, inexpensive, and pollution‐free inorganic flame retardant, which has attracted much attention because of its safety and environment friendliness 16–19 . It achieves flame retardancy by releasing a large amount of water and diluting the fuel that maintains combustion.…”

Biomass‐based composites with renewability and biodegradability have attracted extensive researches, but their applications are hindered by poor mechanical properties and flame retardancy. Cellulose ester matrix composites (CEMC), a kind of biomass‐based composites, were prepared with inorganic crystals as flame retardant and reinforcement. Cellulose acetate oleate (CAO) prepared by mechanical activation‐assisted solid‐phase reaction was used as thermoplastic matrix. Hydrophobic oleate‐magnesium hydroxide (O‐MH), which was surface‐modified with oleic acid, was embedded into CAO to prepare O‐MH/CAO composites by hot pressing. The introduction of oleoyl contributed to favorable thermoplasticity of cellulose ester, resulting in enhanced thermal stability and mechanical properties of CEMC. The uniform dispersion of O‐MH in the CAO matrix via metal–organic coordination increased the mechanical properties and flame retardancy of O‐MH/CAO composites, ascribing to the toughening effect and combustion inhibition effect induced by O‐MH. This study provides a feasible technology for fabricating the CEMC with outstanding thermal stability and mechanical properties.
