In this report, we develop a simple and controllable coating strategy to decorate h-BN with a cyclotriphosphazene-containing boronate polymer(CPBP), thus forming [email protected] core-shell nanoplates with different shell thicknesses. By introducing [email protected] into epoxy resin(EP),we have found that the thermal stability, flame retardant and mechanical performances of the as formed nanocomposites greatly relies on the CPBP shell thickness. Also, our design effectively improve the compatibility between h-BN nanoplates and polymer matrix and regulate the corresponding interface. The nanocomposites show the highest limiting oxygen index (LOI) of 28.1 % and reach V-0 rating in the vertical burning test at loading amount of 2.5 wt.%. Also the heat and smoke releases of nanocomposites during burning are significantly reduced. The flexural strengths and modulus of the nanocomposites are at most 42.12 % and 27.85 % higher than that of pure EP. The glass transition temperature and dynamic mechanical property of the nanocomposites are both improved.

在本报告中，我们开发了一种简单且可控制的涂层策略，以用含环三磷腈的硼酸酯聚合物（CPBP）装饰h-BN，从而形成具有不同壳厚度的[电子邮件保护]核壳纳米板。通过将[电子邮件保护的]引入环氧树脂（EP）中，我们发现所形成的纳米复合材料的热稳定性，阻燃性和机械性能在很大程度上取决于CPBP的壳厚度。同样，我们的设计有效地提高了h-BN纳米板与聚合物基质之间的相容性，并调节了相应的界面。纳米复合材料显示出最高的极限氧指数（LOI）为28.1％，并且在垂直燃烧试验中在2.5重量％的负载量下达到V-0等级。燃烧过程中纳米复合材料的热量和烟雾释放也大大减少。纳米复合材料的弯曲强度和模量比纯EP分别高42.12％和27.85％。纳米复合材料的玻璃化转变温度和动态力学性能均得到改善。
