Abstract

Nanocellulose (NC) is a biomaterial with prospective use as a futuristic material. NC-based materials have several diverse uses, and their demand is growing every year. However, because of their highly flammable nature, the use of NC in harsh settings is greatly restricted. Hence, it is crucial to minimize the risk of fire caused by NC-based materials to maintain a superior level of performance. To diminish the inherent flammability of these substances, flame-retardant elements are often added as additives to produce flame-retardant nanocomposites. Hence, in this review, we have provided a comprehensive summary of the characteristics of NC and the principles and categorization of flame retardants. Subsequently, we have discussed the methods used for the synthesis and characterization of NC-based flame-retardant materials. It also delves into the historical progressions in these materials, intending to enhance the ability to resist flames. The article investigates the fire resistance properties of several materials based on NC, including aerogels, coatings, films, and textiles. The objective of this review is to provide a comprehensive analysis of the future directions and advancements in multi-functional flame-retardant NC materials, with a focus on their potential applications in harsh situations.

在纳米纤维素材料中添加阻燃剂的战略见解：综述

纳米纤维素（NC）是一种具有未来用途的生物材料。以 NC 为基础的材料有多种用途，其需求量每年都在增长。然而，由于其极易燃烧的特性，NC 在恶劣环境中的使用受到很大限制。因此，最大限度地降低数控材料引发火灾的风险以保持其卓越的性能水平至关重要。为了降低这些物质固有的易燃性，通常会添加阻燃元素作为添加剂，以生产阻燃纳米复合材料。因此，在本综述中，我们全面总结了纳米复合材料的特性以及阻燃剂的原理和分类。随后，我们讨论了用于合成和表征基于 NC 的阻燃材料的方法。文章还深入探讨了这些材料的历史进程，旨在提高其阻燃能力。文章研究了几种基于数控技术的材料的阻燃特性，包括气凝胶、涂层、薄膜和纺织品。本综述旨在全面分析多功能阻燃数控材料的未来发展方向和进展，重点关注其在恶劣环境中的潜在应用。

期刊介绍： Nano-Structures & Nano-Objects is a new journal devoted to all aspects of the synthesis and the properties of this new flourishing domain. The journal is devoted to novel architectures at the nano-level with an emphasis on new synthesis and characterization methods. The journal is focused on the objects rather than on their applications. However, the research for new applications of original nano-structures & nano-objects in various fields such as nano-electronics, energy conversion, catalysis, drug delivery and nano-medicine is also welcome. The scope of Nano-Structures & Nano-Objects involves: -Metal and alloy nanoparticles with complex nanostructures such as shape control, core-shell and dumbells -Oxide nanoparticles and nanostructures, with complex oxide/metal, oxide/surface and oxide /organic interfaces -Inorganic semi-conducting nanoparticles (quantum dots) with an emphasis on new phases, structures, shapes and complexity -Nanostructures involving molecular inorganic species such as nanoparticles of coordination compounds, molecular magnets, spin transition nanoparticles etc. or organic nano-objects, in particular for molecular electronics -Nanostructured materials such as nano-MOFs and nano-zeolites -Hetero-junctions between molecules and nano-objects, between different nano-objects & nanostructures or between nano-objects & nanostructures and surfaces -Methods of characterization specific of the nano size or adapted for the nano size such as X-ray and neutron scattering, light scattering, NMR, Raman, Plasmonics, near field microscopies, various TEM and SEM techniques, magnetic studies, etc .
