Abstract：
The flame-retardant paper has gradually evolved into a necessary material in various industries as a result of the rising importance of fire safety, energy efficiency, and environmental preservation. Traditional cellulose paper requires the addition of a large amount of flame retardants to achieve flame retardancy, which poses a serious threat to mechanical quality and the environment. Therefore, there is an urgent need to develop inorganic fiber flame-retardant paper with good flexibility, high thermal stability, and inherent flame retardancy. Herein, inspired by the \"brick-and-mortar\" layered structure of nature nacre, we developed a layered composite paper with a unique alternating arrangement of organic-inorganic fibers by synergistically integrating environmentally sustainable basalt fiber (BF) and high-performance aramid nanofibers (ANFs) through a vacuum-assisted filtration process. The as-prepared ANFs/BF composite paper exhibited low thermal conductivity (0.024 W m-1 K-1), high tensile strength (54.22 MPa), and excellent flexibility. Thanks to its excellent thermal stability, the mechanical strength remains at a high level (92%) after heat treatment at 300 °C for 60 min. Furthermore, the peak heat release rate and smoke generation of ANFs/BF composite paper decreased by 44.6 and 95.3%, respectively. Therefore, the composite paper is promising for applications as a protective layer in flexible electronic devices, cables, and fire-retardant and high-temperature fields.
摘要：
随着消防安全重要性的不断提高,阻燃纸逐渐发展成为各行各业的必备材料,能源效率,和环境保护。传统的纤维素纸需要添加大量的阻燃剂来实现阻燃性，这对机械质量和环境构成了严重威胁。因此,迫切需要开发具有良好柔韧性的无机纤维阻燃纸，热稳定性高,和固有的阻燃性。在这里，灵感来自“砖与砂浆”分层结构的自然珍珠母，我们通过真空辅助过滤工艺协同整合环境可持续玄武岩纤维（BF）和高性能芳纶纳米纤维（ANF），开发了一种有机-无机纤维独特交替排列的层状复合纸。所制备的ANFs/BF复合纸具有较低的热导率（0.024Wm-1K-1），高抗拉强度（54.22MPa），和出色的灵活性。由于其优异的热稳定性，在300°C下热处理60分钟后，机械强度保持在高水平（92％）。此外，ANFs/BF复合纸的峰值放热率和发烟率分别下降了44.6%和95.3%,分别。因此,该复合纸有望作为柔性电子设备的保护层应用，电缆,以及阻燃和高温领域。
