“…In addition to the ignition time, the slope and value of the THR curve could also be used as an indicator of slow ignition. 33 The slope of the THR curve of C/W was clearly reduced, in which THR decreased from 47.38 MJ/m 2 to 26.03 MJ/m 2 , suggesting that CaCO 3 is a noncombustible inorganic material that could effectively reduce the heat release of combustible gases by forming a dense protective layer on the surface of the wood as it adheres to the wood surface. 8 The first phase of S/C/W reached a maximum HRR value of 173.42 kW/m 2 , which was 34.48% lower than the first peak value of the control because of the interaction between SA and the cellulose and hemicellulose in the wood, and thus reduced the oxidative decomposition of cellulose and hemicellulose.…”

Inspired by the natural matrix-mediated biomineralization, wood composites were prepared by vacuum impregnation using the gel effect of sodium alginate (SA) on calcium ions, which improved the mechanical properties, flame retardant, and smoke suppression properties of the wood composites. Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and scanning electron microscopy (SEM) confirmed that the SA inducer had promoted the orderly deposition and directional crystallization of calcium carbonate (CaCO 3 ) inside the wood cell walls and intercellular spaces. The density and weight gain rate of the biomimetic mineralized wood showed that CaCO 3 effectively adhered to the interior of wood with SA as an inducer. The compressive and flexural strengths were 15.65% and 37.66% higher than those of the control, respectively. Thermogravimetric analysis (TG) proved that SA alleviated the thermal decomposition and complete combustion of the mineralized wood and improved the thermal stability. Microcalorimetry (MCC) and cone calorimetry (CONE) analyses revealed that the maximum heat release rate (HRR), total heat release (THR), and the total smoke production (TSP) rate of the mineralized wood was reduced by 59.51%, 48.52%, and 51.67%, respectively, compared with those of the control. This research demonstrates the in situ synthesis of CaCO 3 within the cellular microstructure of the poplar which is using it as a biotemplate. With the enhancement of the flame retardant property and others, the wood composite biomimetic mineralized materials modified by CaCO 3 and SA could be utilized more widely in the construction industry or other fields.

Los compuestos de madera-plástico han sido objeto de interés por parte de investigadores por sus propiedades mejoradas, en comparación con los productos basados únicamente en plástico o madera. Sin embargo, durante algunos años se han estudiado los efectos de algunos nanorrellenos sobre estos compuestos. La presente investigación tiene como objetivo la revisión de las investigaciones más relevantes en trabajos publicados en revistas científicas sobre los efectos de los nanorrellenos en los compuestos de madera y plástico. El material bibliográfico consultado se encuentra entre los años 2011 y 2021. En este estudio se discuten los beneficios ambientales, la limitación de las aplicaciones y los efectos de algunas nanopartículas en estos compuestos con plástico virgen y reciclado. Se concluye que los nanocompuestos de madera-plástico son una excelente opción de material con aplicaciones potenciales. No obstante, se sugiere visualizar las alternativas que existen para el uso de nanocompuestos madera-plástico en el diseño de producto.

“…Layer-by-layer (LbL) assembled films have recently been explored as one alternative, with its ambient processing and customizability to achieve desired properties . LbL assembly typically consists of alternating deposition of oppositely charged polyelectrolytes, which are held together via electrostatic interactions, until a desired number of bilayers (BLs) is reached. , With this method, various combinations of polymeric and/or inorganic materials can be used to achieve desired properties, such as gas barrier, − heat shielding, − and fire retardant. ,− …”

Soft furnishing fires contribute to 29% of fire causalities and $8.7 billion in direct property damage annually in the United States. Polyurethane foam (PUF), a common component in soft furnishings known for its comfort and flexibility, can emit toxic gases and propagate fires due to melt dripping when ignited. Various acid salts were added to a layer-by-layer assembled nanocoating, consisting of chitosan and carboxymethyl cellulose, to improve PUF flame retardancy and to understand the influence of salt-doping on flammability. The 20-bilayer phosphoric acid-doped coating exhibits a self-extinguishing behavior, with a 67% reduction in peak heat release rate while maintaining the structural integrity of the foam. By depositing this completely environmentally sourced coating on PUF, the inherent danger of soft furnishing fires can be significantly reduced in a nontoxic manner.
