“…The flame-retardant effect of MOFs used alone is not outstanding relative to the reported novel flame retardants. 33,34 One of the main reasons is that a large number of flammable ligands contained in their structures do not contribute to the flame-retardant performance. The flame-retardant functional substitution of the original ligands through the ligand replacement strategy provides good insight for improving the flame-retardant capability of MOFs.…”

“…For graphite, the diffraction peak at 2θ = 26.3 corresponds to the (002) reflection, 36 and it shifts to 17.7 after hydrothermal treatment and modification with flame retardant, indicating that the spacing and dispersibility of graphene increased after hydrothermal treatment. 37 Figure . 1c, d show the 31 P and 1 H NMR spectra of phosphorus/nitrogen-containing silane compound D, respectively. The attribution of these peaks is as follows: 1 H NMR (DMSO-d 6 , 400 MHz): δ = 0.33 ppm (q, 2H, Si CH 2 CH 2 ), 1.1 ppm (q, 2H, CH 3 CH 2 O Si ), 1.22 ppm (q, 2H, CH 3 CH 2 CH 2 -), 2.49 ppm (q, 2H, CH 2 CH 2 NH ), 3.52 ppm (q, 2H, CH 3 CH 2 O Si ), 7-8 ppm (m, Ar H).…”

Enhancing the flame retardancy with minimal impact on the mechanical and thermal performances of polymers remains a challenge. This study synthesized a phosphorus/nitrogen‐containing silane compound (D) using polyformaldehyde, KH‐550, and 9,10‐dihydro‐9‐oxa‐10‐phosphaphenanthrene‐10‐oxide (DOPO) as raw materials through the Kabachnik‐Fields reaction. After that, D was grafted onto the surface of graphene after hydrothermal treatment to obtain a nano hybrid flame retardant (D‐GR). And D‐GR/EP composites exhibited good flame resistance (LOI = 30.1% and UL‐94 reaches the V‐1 rating) even if the load on D‐GR was 1 wt%. Indeed, the total heat release, the peak heat release rate (PHRR), and the total smoke release of 1% D‐GR/EP dropped by 13.54%, 28.62%, and 44.32%, respectively, in comparison to pure EP. The mechanical performance of 1% D‐GR/EP was effectively maintained, as indicated by the results of impact, tensile and flexural tests. A systematic evaluation indicated that the accession of D‐GR effectively inhibited smoke and heat releases that are ascribed to the synergistic effect of phosphorus/nitrogen‐containing silane compound and graphene. In this study, a facile method was provided for the synthesis of halogen‐free flame‐retardant epoxy composites with superior performances. The combustion products of the as‐prepared composites complied with green and environmental protection standards.

“…A self-assembly approach based on coordination bonding and electrostatic interactions was used to build copper organophosphate nanosheets evenly on the surface of graphene oxide (GO). This study presented a novel interfacial approach for creating functional nanosheets in polymers with good interface compatibility and great flame-retardant efficacy [ 28 ].…”

BISCO plaster (BRP) is an environmentally friendly material with high mechanical properties and is considered a great elective to conventional materials such as gypsum and cement. Our investigation seeks to examine BISCO plaster (BRP) and a mixture of resin and hardener in three proportions (30%, 45%, and 60%) to achieve our ultimate goal, which is to preserve the environment and achieve the vision of the Kingdom of Saudi Arabia 2030 to reach zero carbon emissions by 2060? Emissions tests were performed, and although the CO2 level was zero, they emitted SO2 sulfur dioxide and NO2 nitrogen dioxide, and 60% was the lowest emission rate. We also used ANSYS 2023 R1 software to compare them with their mechanical properties resulting from tensile and compression testing. In this study, we looked closely at the mechanical characteristics of different materials designed for wall coverings, with particular emphasis on their environmental sustainability. We carried out experiments to gauge the tensile and compressive stress on samples with varying mixing ratios. Our main objective was on crucial mechanical properties such as the modulus of elasticity, ultimate tensile strength, yield strength, yield strain, modulus of resilience, and ductility. Through meticulous scrutiny, we determined that the amalgamation of these mechanical attributes at the 30% mixing ratio provides an optimal combination for attaining structural integrity, adaptability, and resilience in wall coverings. Significantly, this ratio also underscores a commitment to environmentally conscious material selection. Our study offers important new insights into the selection of wall covering materials by providing a detailed understanding of their mechanical behavior under various stress conditions. It aligns with the increasing significance of environmental responsibility in contemporary design and construction. By emphasizing the 30% mixing ratio, our findings establish a foundation for informed decision making, promoting the utilization of sustainable materials that achieve a balance between strength, flexibility, and longevity. This ensures optimal performance in practical applications while simultaneously minimizing the environmental impact.
