Abstract Flame retardants (FRs) are applied to select consumer products such as baby clothing, construction materials, electronics and furniture upholstery to slow or prevent fire ignition or growth by physical/chemical mechanisms. The most commonly used FRs have historically been halogenated molecules. However, their bioaccumulation in mammals has been investigated, leading to some of them to be banned. As an alternative FR, this study investigated the potential of carbonaceous nanomaterials (CNMs) such as carbon nanotubes (CNTs) and graphene oxide (GO) coating material on polyester fabric. CNMs mass loadings on fabrics were verified by programmed thermal analysis (PTA) and tested for flame retardancy using a new assessment approach based on National Fire Protection Association (NFPA) method 705. Compared with traditional FRs, select CNMs showed similar flame retardancy at lower mass loadings. The oxygen content of CNMs, as measured by X-ray photoelectron spectroscopy (XPS), emerged as a critical parameter with higher oxygen content resulting in reduced flame retardancy of the coating. Non nano-sized carbonaceous materials such a carbon black did not exhibit the same flame retardant properties as CNMs. Multi-walled carbon nanotubes (MWCNTs) and amine functionalized multi-walled carbon nanotubes (e.g., NH2-MWCNT) required significantly lower mass loadings to achieve flame retardancy similar to traditional FRs and hence are promising alternatives that warrant further investigation.

碳纳米材料在涤纶织物上的阻燃性能

摘要 阻燃剂 (FRs) 用于选择消费品，如婴儿服装、建筑材料、电子产品和家具内饰，以通过物理/化学机制减缓或防止着火或生长。历史上最常用的阻燃剂是卤化分子。然而，已经研究了它们在哺乳动物中的生物积累，导致其中一些被禁止。作为替代 FR，本研究调查了碳纳米材料 (CNM)，如碳纳米管 (CNT) 和氧化石墨烯 (GO) 涂层材料在聚酯织物上的潜力。CNMs 在织物上的质量负载通过程序热分析 (PTA) 进行验证，并使用基于美国国家消防协会 (NFPA) 方法 705 的新评估方法测试阻燃性。 与传统的阻燃剂相比，选择的 CNM 在较低的质量负载下表现出类似的阻燃性。通过 X 射线光电子能谱 (XPS) 测量的 CNM 的氧含量成为一个关键参数，氧含量越高，涂层的阻燃性就越低。非纳米尺寸的碳质材料如炭黑没有表现出与 CNM 相同的阻燃性能。多壁碳纳米管 (MWCNT) 和胺功能化多壁碳纳米管（例如，NH2-MWCNT）需要显着较低的质量负载才能实现类似于传统 FR 的阻燃性，因此是值得进一步研究的有前途的替代品。随着氧含量的增加，涂层的阻燃性降低，成为一个关键参数。非纳米尺寸的碳质材料如炭黑没有表现出与 CNM 相同的阻燃性能。多壁碳纳米管 (MWCNT) 和胺功能化多壁碳纳米管（例如，NH2-MWCNT）需要显着较低的质量负载才能实现类似于传统 FR 的阻燃性，因此是值得进一步研究的有前途的替代品。随着氧含量的增加，涂层的阻燃性降低，成为一个关键参数。非纳米尺寸的碳质材料如炭黑没有表现出与 CNM 相同的阻燃性能。多壁碳纳米管 (MWCNT) 和胺功能化多壁碳纳米管（例如，NH2-MWCNT）需要显着较低的质量负载才能实现类似于传统 FR 的阻燃性，因此是值得进一步研究的有前途的替代品。
