摘要

本研究通过二苯基磷酸和咪唑的中和反应，以及随后的idpp辅助球磨和环保水净化工艺，制备了一种新型咪唑二苯基磷酸-氮化硼纳米片（IDPP-BNNS）杂化填料。采用IDPP和IDPP- bnns作为固化剂和填料，使环氧树脂具有优异的阻燃、导热、电绝缘等多功能性能。与环氧树脂相比，添加5 vol.% IDPP-BNNS的环氧树脂的峰值放热率（PHRR）和总放热率（THR）分别显著降低了67.9%和71.2%。此外，通过现场测量，其有毒气体和可燃气体的释放百分比显着降低。更重要的是，多功能环氧复合材料具有增强的导热性和优异的电绝缘性能。

Imidazole diphenyl phosphate-boron nitride nanoflakes for significantly enhancing flame retardation and thermal transport performance of epoxy

In this work, a novel imidazole diphenyl phosphate-boron nitride nanoflakes (IDPP-BNNS) hybrid filler is prepared via a neutralization reaction of diphenyl phosphoric acid and imidazole and subsequent IDPP-assisted ball milling and eco-friendly water purification process. IDPP and IDPP-BNNS are used as a curing agent and filler to endow epoxy with superior multifunctional properties of flame retardancy, thermal transport and electrical insulation. Compared to those of epoxy, the peak heat release rate (PHRR) and total heat release (THR) of this epoxy composite with 5 vol.% IDPP-BNNS are significantly reduced by 67.9% and 71.2%, respectively. Moreover, its release percentage of toxic and combustible gases is remarkably reduced by an in-situ measurement. More importantly, the versatile epoxy composite exhibits enhanced thermal conductivity and excellent electrical insulation properties.
